Despite the variety of starting systems for gas turbine engines, they all have a starter that provides preliminary rotation of the engine rotor, an energy source necessary for the starter to operate, devices that supply fuel and ignite the combustible mixture in the combustion chambers, and units that automate the starting process. The name of starting systems is determined by the type of starter and power source.

The following basic requirements are imposed on launch systems, which are aimed at ensuring:

reliable and stable engine starting on the ground in the ambient temperature range from -60 to +60 °C. It is allowed to preheat the turbojet engine at a temperature below - 40 °C, and the high-pressure engine - below - 25 °C;

reliable engine starting in flight over the entire range of flight speeds and altitudes;

duration of gas turbine engine startup not exceeding 120 s, and for piston engines 3...5 s;

automation of the starting process, i.e., automatic switching on and off of all devices and units during the engine starting process;

autonomy of the launch system, minimal energy consumption per launch;

multiple launch capabilities;

simplicity of design, minimal overall dimensions and weight, convenience, reliability and safety in operation.

Currently, the most widely used starting systems are those that use electric and air starters to pre-crank the engine rotor. Accordingly, the systems were named electric and air. Starter energy sources can be on-board, airfield or combined.

Automation of the engine starting process can be carried out according to a time program, regardless of external conditions, according to the engine rotor speed, and according to a combined program, where some operations are performed according to time, and others according to rotation frequency.

When choosing the type of starting system for a particular engine, many factors are taken into account, the most significant of which are: starter power, weight, overall dimensions and reliability of the starting system.

Electric engine starting systems are those systems that use electric motors as starters. Electric starters are used to start the gas turbine engine direct action, in which there is a direct connection through a mechanical transmission with the engine rotor. Electric starters are designed for short-term operation. IN Lately Starter-generators are widely used, which, when starting the engine, perform the function of starters, and after starting - the function of generators.

Electric starting systems are quite reliable in operation, easy to operate, make it easy to automate the starting process, and are also simple and easy to maintain. They are used to start engines that have relatively small moments of inertia, or when the time it takes them to reach idle mode is relatively long. To start engines with high torques, inertia, or with a reduced time to reach idle mode, an increase in starter power is required. Electrical systems are characterized by a significant increase in their mass and overall dimensions with increasing starter power, which is caused by both an increase in the mass of the starters themselves and the power supplies. Under these conditions, the mass characteristics of electrical systems can be significantly worse than other launch systems.

Getting Things Done is often translated into Russian as “putting things in order,” although it would be more accurate to “bring things to the end.” Agree, it is more important not to stuff tasks into lists, but to complete them. This is exactly why you need to make lists, determine priorities and come up with a schedule.

And why is this necessary?

What is the difference between a GTD and a task list?

Is this system really right for me?

As David Allen told Lifehacker, a system can be equally effective or equally useless for both a teenager and a CEO. large company. You need to have a certain mindset, love to organize and plan.

Okay, so what exactly should you do?

1. Collect information and record everything. Write down tasks, ideas, and recurring tasks in a notepad or app. At the same time, the list should always be at your fingertips so that you can’t say: “I’ll add this later.” Even the smallest and most insignificant task should be written down if you are not doing it right now.
2. Write explanations. There should be no tasks like “Prepare for vacation.” Break down big tasks into specific, manageable actions (submit such and such documents to the visa center, buy a towel and sunglasses, download maps to your phone). With a typical task list, we spend more time deciphering than completing. And yes, if you can delegate, delegate.
3. Set your priorities. For each item in the list, provide a specific date and deadline. Add reminders if necessary. Essentially, this is working with both a list and a calendar. At this stage, you should have confidence that you will definitely not forget anything.
4. Update your lists. To-do lists quickly become outdated: something loses its relevance, something is postponed to the future. The system should work for you. So make sure you always have a list of specific actions so you can get started without delay.
5. Take action. When everything is organized, you can begin to implement your plans. Select a case from the desired category, see what specific actions are required of you, and work. This way you can implement big projects.

Should all things be written down in one list?

Are there any special tools?

There are fans of the file system. One common folder is created on the desktop, in it there are several thematic ones, and each one stores the corresponding lists and necessary materials.

In general, choose what is convenient for you.

The main requirement: the tool should always be at your fingertips so that you can transfer the task from your head to paper or to an application. For example, when your boss comes to you and instructs you new task, and at this time you are working on something else.

How to get more value from GTD?

And yes, no system can do everything for you, so don’t get too carried away with making lists, don’t forget to take action. GTD is a tool that helps you get rid of stress and not forget anything. But how you manage your time is up to you.

Our reader Oleg Bondarenko shares his proven GTD system for organizing his affairs and his whole life. It's no secret that we know almost everything about GTD and similar mechanics, but we are rarely able to use them for a long time. We are sure that the success story in this field will be interesting to you.

I divide incoming tasks, ideas, thoughts as follows:

• Anything that can be shoved right away onto another performer, I immediately shove it off. I add a reminder task “Check execution”.
• What can you do right now in 5-15 minutes? I sit down and do it.
• What requires more time or cannot be done right now. This also includes reminder tasks like “Check the status of the XXX project.” I immediately enter it into the list of tasks on my phone or Google Tasks - everything is synchronized.
• What is interesting and may be promising. I throw them in a bunch into Evernote. I review it about once a week and sort it into notebooks. Something grows into tasks.

More details on point 3.

To successfully maintain a list of tasks, strict formalization and minimization of costs for managing and obtaining data are necessary. This is achieved as follows.

Each task has a structured name like: Project | Object | Action

Project– this is a large grouping of tasks, an abbreviated code like HOME, OFFICE, CLIENT1, ... For each Project there should be an average of 1-10 tasks. If there are consistently more tasks for the Project, I allocate part of it to an additional Project. Thus, task grouping is always one-level. As practice has shown, a more visual grouping of tasks in the form of a multi-level tree is actually unnecessarily labor-intensive and reduces motivation to use the system effectively.

Searching for tasks within a Project is performed using basic functions: searching or sorting – my favorite method.

An object- this is an object or person on whom an action needs to be performed. Everything is simple here.

Action– an elementary action that must be performed on an Object.

Another critical point: every task contains execution date. If you are not sure about the due date of a task, set the current one. If you set the current date and do nothing else, tomorrow the task will be on the overdue list and you will have to make a decision on it. For example, put it in notes about life.

Sometimes, for a certain Project, a list of tasks emerges, the timing and sequence of execution of which is not clear at the moment. In this case, I create a general task of the form: Project Tasks. In the comments I list the list of tasks. Over time, the situation becomes clearer, something is crossed out, something is completed, something grows into a separate task. In any case, even from such a group record, I determine the date when it is necessary to contact it and conduct an audit.

And one last thing. In my practice, approximately 50% of tasks are not completed(or cannot be executed) on the selected date. Much does not depend on me. Tasks like “Check project status” are generally lengthy and require periodic attention. Something is being clarified and supplemented. Such tasks are constantly postponed to later dates. This is normal (by the way, this is a huge plus of electronic organizers). Manual labor regarding rescheduling, it is also useful in the sense that it sometimes prompts important thoughts.

Today I will talk about chips GTD technologies that will allow you can accomplish more, get tired less, increase the efficiency of your own work, reduce stress and increase life satisfaction.

Do you know that your consciousness will constantly remind you of those things and tasks that you thought about doing, but left unattended?

Surely, thousands of unfinished tasks, unprocessed processes are already hanging like a dead weight in your brain, which consume your internal resources, strength, energy, and you don’t even know about it. All this creates stress and deprives you of energy. You perform worse on new tasks because your head is full of old ones.

I talk about how to finally clear your head of all this information and improve your work and life in this article.

You've most likely heard the acronym "GTD", which stands for Getting-Things-Done. This philosophy or technology has become very popular due, in part, to media coverage. Newspaper journalist the Guardian named David Allen, the author of the GTD philosophy, as the person who is called upon to bring order to the universe.

GTD is not just a time management system necessary for busy top managers with no personal life. This is a system for optimizing and organizing not only work, but thinking, consciousness, giving instructions on how to “cleanse” the consciousness of unnecessary mental burden, open up space for creativity, new ideas and create psychological prerequisites for comfortable and organized work. This system is designed for both a businessman with a million projects and a housewife who needs to take care of children, leaving time for reading fiction, and for a student who is preparing to enter college.

Despite the fact that this phenomenon is well-known, not everyone knows what it is and how it can help you personally. Therefore, today I will literally tell you what it is. After reading this article, you will be able to bring order into your life and thinking today and almost immediately see positive results from these life innovations.

What prompted me to start organizing my affairs?

Feelings of anxiety and guilt do not arise from too much work. It appears automatically when you break agreements with yourself.
~David Allen

Not long ago I was faced with the need to organize my own work schedule, in which I discovered a lot of bottlenecks. About 10 years ago, due to my problems with concentration, it was extremely difficult for me to do any work for a long time. Over time, I began to work on improving my focus and discipline. I began to learn to relax and... It bore fruit.

I was able to create my own project, promote it, quit my hired job and start working for myself, as I had dreamed of. I had a sense of progress in terms of working on myself, which was enhanced by the stark contrast between my present and my past. Some time ago I could not cope with studying at the institute and simple hired work, but now I worked in a disciplined manner for the good of own project and the people he benefits by working day after day, independently, and not “under pressure.”

Only then did I notice that this was not the limit. The feeling of success temporarily hid from me the problems that had arisen in the organization of my work.

I have a wide variety of work: letters in the mail, articles on the website, comments, work with students of the “NO PANIC” course, etc. and so on. All this requires good organization. I realized about its absence from the fact that a lot of unread letters had accumulated in the mail, but marked as “important”. Word files with “plans for 2015” and “tasks for February 2016” were scattered all over the hard drive. In the drawers were notebooks with notes, ideas, and, again, descriptions of the tasks that I must complete. Needless to say, I very rarely opened these files and consulted these lists. And this happened not so much because of my lack of discipline, but because it all had some kind of awkward appearance, causing an internal feeling of the futility of all these planning exercises.

I realized that I still don’t have time to do a lot, although I could do more.

In general, attempts to make an organized list of tasks and, most importantly, follow it, failed time after time.

Of course, I completed urgent daily tasks, but at the same time I felt how many “tasks” and “ideas” were in limbo. All this resulted in me feeling less satisfaction from work. There were days when I allowed myself to finish early. I went outside, got on my bike, but instead of enjoying the free time that I wouldn’t have had if I worked in an office, I was haunted by the feeling that I hadn’t done something, that I hadn’t done something. managed. Perfectionist attitudes began to emerge in my thoughts: “I should be doing more”, “I’m not working hard enough”. But I understood that the problem was not in the amount of work, but in its organization.

So I decided to start organizing my entire workspace. I picked it up great book David Allen - Getting Things Done. I've heard about the GTD system for a long time, but only now I decided to take a closer look at it.

What is GTD?

“Unfinished business actually remains unfinished in two places: in reality and in your head. The unfinished business in your head absorbs the energy of your attention because it haunts your conscience.”
~Brahma Kumaris

When I first got this book, I expected to read in it some banal time management tips that I had seen in other sources, like “divide things into important and unimportant”, “delegate what can be delegated.”

“Say, ten years ago you promised yourself to clean out your closet, but today you haven’t done it... we can say that in this case you have been cleaning the closet 24 hours a day for the last 10 years!”

But the author speaks of this standard “Time Management” approach as limited and, in many ways, ineffective. I liked that David Allen is no longer addressing considerations "effective work", and to possibilities and limitations of human consciousness. To organize our own affairs so that they do not conflict with the peculiarities of our thinking. The GTD approach is entirely based on insights into how our brain works, how it accumulates information, and how it processes unsolved problems.

The most basic psychological premise of this philosophy is the fact that any life tasks, be it completing an important project or a trip to a monastery for a meditation course, are perceived by our brain as unresolved and kept in memory, causing mental stress, if we do not formalize these tasks in the form of specific next actions within the framework of an external information storage system.

Don't be alarmed and don't re-read this paragraph! Now I will explain what all this means. Good example is given in the book itself, “Getting Things in Order.” Let's say, ten years ago you promised yourself to clean out your closet, but today you haven't done it. How did your brain store and process information about this task all these ten years?

The fact is that psychologists are sure that our consciousness, in the context of setting tasks, has no ideas about the past and future. These ideas exist only conceptually, but they are not present in the information processing algorithms themselves within consciousness.

If you promise yourself to take your car to the service next week and at the same time try to keep this commitment in memory, then your mind will believe that you should do it right now, today, constantly reminding you of this. And tomorrow it will also count the same.

The task will be in the “immediate solution required” status every day until you go to the service center.

Going back to the cluttered closet example, in this case you have been cleaning your closet 24 hours a day for the last 10 years! Your consciousness regarded this task as unfinished, leaving a place for it in your memory space, creating tension and dissatisfaction due to unfinished work.

And in order to free your memory and free your mind from unfinished processes, reminders of which consume your mental resources (just as background processes on a computer consume processor and memory resources, making the machine slower), you need to take two key actions.

1. Transfer a task from internal memory (your brain) to external memory (your computer, notebook, tablet, phone)
2. Decide what the next specific action will be regarding the task at hand. For example, the global task “fix the car” may consist of many simple actions. The very first action may be: “find suitable spare parts on the Internet.”

In this case, your consciousness will free up your internal memory and stop constantly reminding you of what you haven’t done yet. After all, you have transferred all these tasks to an external system.

These are, in principle, the key points of GTD technology on which everything relies. If you understand this principle, then you already have a general understanding of what GTD is. This system effective management affairs, creating ideas, which is based both on external organization tasks within the framework of records, calendars, reminder systems, and for internal optimization of the work of consciousness.

Moreover, these two levels are interconnected. External order serves as a prerequisite and tool for an organized and “pure” consciousness. And a clear mind allows you to work more efficiently* and get less tired.

(*Although I use the word “work”, it does not refer exclusively to professional activities. In this context, work concerns any business at all. Planning a vacation is also work. Just like thinking about the problem of a relationship with your other half).

Tip 1 - Decide what the next action will be

“When you plan your activity (implementation intention) and decide what actions you will perform in what context, you almost automatically tune in to the desired behavior instead of mustering all your will into a fist and forcing yourself to do something.”
~D. Allen

If you read a book "How to get things in order", then you will understand that this is just the most Golden Rule. The author constantly returns to him. Moreover, he is obsessed with teaching the whole world to think about the next action!

Yes, the rule is important, but it takes time and discipline for it to become a habit.

The fact is that we, as a rule, talk about problems in a general and abstract way. “We need to make sure that the child learns better”, “I need to become calmer in order to participate less in conflicts”. Of course, you need to keep the big picture in mind, but in order to bring things to completion, you need to move to the next level of planning, namely, think about the next action.

In the examples we have considered, this could be:

• “Find articles on the Internet about developing willpower, discipline and fighting laziness. Or find in bookstore book on this topic."
• “Read about what relaxation techniques there are.”
• “Schedule a time to talk with your son about his academic problems.”

The next action does not have to be a physical action. “Think about whether I need to go to college at all” is also an action. You can just think about the task, you don’t have to start. But by taking just this step, you will already free up part of your brain.

We cannot solve all the problems in our lives. Therefore, it is important to understand that the decision to “do nothing” is also a decision.

This event allows you not only to relieve your mind, but also to recharge yourself with motivation. Many tasks, when we imagine them in our minds, seem impossible or very difficult. “Oh my God, I’ll have to dismantle my entire summer cottage, it’s a job without end!” But it will be much easier for us to start it if we outline a plan in the form of the following actions: “Find the right tools on the Internet”. This is easier, isn't it? And when we do this, we will feel the satisfaction of being one step closer to the final goal.

Tip 2 - Transfer to an external system

As you may remember from this article, relying on memory is not only unreliable, but also inefficient in terms of using your brain's resources. Therefore, David Allen strongly recommends moving all tasks to an external system to free up memory.

An external system can be a tablet, phone, notepad, computer, notebook. Any convenient medium you can work with.

By the way, this is what my task list looks like after pre-processing. I removed a lot of unnecessary things from there, things that I had already done or decided not to do at all. That is, at the very first stage and before applying the “two-minute rule” (more about it below), it was much larger.

It wouldn’t hurt to say that the task list should be organized, convenient, and accessible from anywhere at any time. Need it keep up to date and modify as necessary. You need to contact him to check with him about the progress of your projects.

(That is, not like it was for me (and maybe for you too): piles of sheets and notebooks in different places in my workspace that I never touched.)

And of course!!! Every task should be written down as a next action!

Tip 3 - Organize tasks by context

“It doesn’t take much strength to do something. It takes a lot more effort to decide what to do.”
~ David Allen

I didn't notice that the book gave any direct advice on how to prioritize tasks. David Allen is confident that the importance of various tasks for our consciousness is not so critical, since both large and small worries take up space in our consciousness and we need to do them all (or decide not to do them). A trivial task not done, information about which is stored in the mind, can distract you from more “important” matters. However, it does provide an excellent method for organizing tasks by context or energy level.

I once partially came to this method myself intuitively, but then I forgot about it due to the fact that I did not formalize it and did not make it a habit. For example, there is a large list of tasks. Some tasks require a lot of energy to complete.

For me this is “Responses to comments and support for students”, “Articles”.

For some, it’s not enough, for example, “paying for hosting”, “working with electronic invoices”. I can easily do this when I don't have enough time for articles.

Decisions about “what should I do now” Firstly, they took a lot of energy from me, and, secondly, they negatively affected my motivation. I couldn't find an activity that best suited my energy level and as a result I quit work, ending the workday with the notorious feeling that I hadn't accomplished something. Now, if I have little strength and a lot of time, I can simply do the work that does not require a lot of energy. I can just look at the list with the title "low energy" and make something out of it. Everything ingenious is simple!

You can also organize the list of tasks by context, for example, “at the computer”, “in the store” etc. Many other ways to organize are presented in the book.

Chip 4 - “Two Minute Rule”

A rather simple, but extremely effective rule. If we organize our to-dos into a list of reminders, we may be overwhelmed by the size of the list. Luckily, there is a good and easy way to give it a thorough cleaning.

No need to write it down: “Reply to a friend’s letter when you have free time”, if this answer takes you less than 2 minutes!

Just answer right now and free your mind and task list from this matter. When, after reading D. Allen's book, I began to clear out my mailbox, I discovered many unanswered letters there. Of course, once upon a time, I ticked them off as important tasks, but then I forgot about them.

As a result, after conducting the review, I answered a lot of old letters, and it didn’t take me that much time. Some of my readers received a response from me after a year! Please don't be offended by me, this is the result of an overcrowded mailbox and poor organization of affairs. Now I try to answer immediately if I understand that the process of reading and processing the letter will take at least 5 minutes. 2 minutes is not strict, let everyone determine the maximum time period for themselves.

In general, the “two minute rule” is formulated as follows. If, while processing your task list, you find something that will take less than 2 minutes to complete, just do it.

Tip 5 - Write down ideas

Surely you have noticed that the most best ideas they come to you about your work when you are not working! Therefore, D. Allen advises to always have something on hand that will help you save ideas: a notepad, an electronic tablet, etc. The point here is not only that it will help you not to forget valuable ideas and free your memory from information. Yes, this is also important.

Allen believes that “form determines principles.” According to him, a person “There may be a subconscious reluctance to think about anything because you don’t have a place to write down ideas.”

I tested this on myself. When I traveled in India, I always carried either a notepad or a phone with me so I could write down thoughts and ideas. And my consciousness was simply gushing with them. I wrote down my thoughts while shaking on the seats of Indian trains, on the tops of picturesque hills, in the ruins of ancient temples, lying under the Sun or under the fan in a hotel room.

I was calm, firstly, from the fact that I had where to record the ideas that arose, and, secondly, thanks to the fact that I did not need to keep the ideas in my memory with all my might, I knew that I could always return to them .

Of course, it is important not only to form the habit of writing down your ideas, but to review this list regularly.

By the way, I now also write down quotes and valuable rules from other people, rather than trying to keep them in my memory.

Tip 6 - Don't separate life and work

"Uncollected open questions equalized in terms of the stress they cause and the attention they require."
~David Allen

As I already wrote, for our brain there is not much difference between the tasks: “finish a work project”, “discuss a problem in a relationship with my wife”. Both tasks occupy our memory and consume mental resources, no matter where we are, in the office, at home or on vacation.

And the practical conclusion from this principle became a great discovery for me. Previously, when I started work, I put off thinking about personal and life problems for later. “After all, I’m working now! I am busy!"- I thought.

But in fact, the fact that these tasks are “hanging” in my mind can prevent me from working focused and effective (here I mean work in the usual sense, like professional activity). And the worst thing we can do is leave them hanging. Therefore, sometimes it makes sense to solve some urgent family matters, routine tasks, even think about “philosophical questions” that really bother you before you sit down to work.

It is clear that there are problems here. You can immerse yourself in this thinking for so long that you never start working. Therefore, it is necessary to approach this principle carefully and consciously. Another good solution would be to write down on your to-do list: "think about the meaning of life" and free your head from reminders of this.

Tip 7 - Benefits for psychotherapy

“The fruitless and endless repetition of a thought in your head reduces the ability to analyze and act.”
~David Allen

I couldn’t help but think about applying this technology to the field of psychology and psychotherapy, the prevention of neuroses, obsessive states, and destructive attitudes.

There are different methods of getting rid of obsessive, negative thoughts. Some psychologists recommend subjecting such thoughts to careful logical analysis. Others use calming and realistic affirmations.

Although I use these approaches in my practice of helping people with panic attacks, I understand that the capabilities of our logic in a state of anxiety and panic are very limited, and there is always a chance that such an analysis will be turned against the one who uses it. So I basically recommend just patiently not reacting to intrusive thoughts.

But I also think that the principle of “identify the next action” and “focus on the goal” can be used very well in relation to intrusive thoughts and negative attitudes.

Let's say you suffer from hypochondria.

You think: “I have a terrible and fatal disease.”
Okay, now think: “What’s the next action?”
“We should probably go get checked. But I already went to the doctors this week, the tests didn’t show anything bad!”
Everything fell into place, didn't it?

Or do you have social phobia:

“People don’t accept me, I’m a worthless person”

What's the next action?

"I will work to improve my social qualities and I’ll start with...” or/and “I will learn to accept myself as I am and I will start with...”. Most often, both the first and second skills are required in combination to solve problems of self-doubt, social anxiety, etc. Formulating your next action will not only set you up for the goal, but also show that achieving the goal is possible!

And even if it is not possible, then the next action will be: “I will not do anything about this problem. Because it cannot be fixed. If so, why think about it?”

This approach will help you think not about the problem, but about its solution! Anxious, suspicious, restless people are often very fixated on problems. “I have few friends,” “fear never leaves me,” “everyone thinks badly of me,” etc. They ask more questions: “why” than “what to do about it,” which only creates new anxiety and a feeling of helplessness.

But the question is: “what’s the next action?” immediately sets you on the path to solving the problem (or deciding to do nothing), which can free your head from a whole heap of negative, meaningless thoughts about the problem. In general, try it!

What can you achieve with GTD?

“The problem is not a lack of creativity, but rather removing barriers to the natural flow of creative energy.”
~David Allen

The application of GTD methodology goes far beyond improving labor efficiency. Therefore, by putting at least some aspects of this approach into practice, you will experience not only increased productivity, but also greater clarity of consciousness. The purpose of this system is not only to make you work better, but to free your head from unnecessary thoughts about work and uncompleted tasks. So that you can easily let go of thoughts about what you cannot change or have a solution ready for what needs your action.
