CC, the fastest update power king!

Gas turbine and air engine startup process and our familiar car, motorcycle pneumatic process, basically basically, but actually different!

How is the car and motorcycle pneumatic? When a pneumatic button is pressed, the electric starter drives the flywheel of the engine to rotate. When the engine reaches a certain speed, the engine oil supply system begins to fuel injection, the engine is successfully started, usually, this process will be one second or not One second time.

However, the starting process of gas turbines and aerospace engines is more troublesome.

Like our most familiar cars, motorcycles, the air engine and gas turbine can not rely on their own input, and also require external energy to help boot. After a predetermined start process, the host enters a stable working state.

However, this start-up process is not performed by the ignition switch. First, the starter drives the engine to gradually enter the slow car state. After reaching the slow car status, the oil supply system begins to oil supply to the engine, and then it is ignition. Then slowly increase the speed of the engine to the normal speed.

There are many kinds of starters. In general, it is compressed air. In the early years, there is no APU system above the fighter, and the compressed air carried is only enough to carry out around the air in the air, there is an APU system After that, compressed air can be continued by the APU system, but it can be started several times.

With the injection of compressed air, the blade of the RB211 gas turbine begins slowly. As the speed of the turbine blade is getting faster, the sharp sharpness of the turbine is getting clearer, the harsh, but the king is as if it is Not to be moved, dead staring at the engine speed displayed on the screen, when the engine speed finally arrived at 3250 rpm, Wang Dazhi pressed the intercom point button: "Ignition!

"Ignition!

With the order of Wang Dazhi, a strange voice came from the inside of the gas turbine. Soon, the gas turbine exhaust exit had a large colorful cassic smoke, and the color of the cauterous smoke gradually farsely, the gas generator rotor The speed is also continuously improved, the ignition is successful!

The gas generator is successful, but the face of Wang Dagu is still tight.

For the quality of their own gas generators, Wang Dazhi did not worry, but the gas turbine provided by the Hangput turbine and the Harbane turbine can work smoothly, but he is somewhat unfameful.

Not only is Wang Dazhi, 703, Huaqi University, Hang Auto turbine, Harbane turbine, military special representative, the Special Representative of the MBU ... All participated in this project, the unit, leadership, leadership, At this moment, it is not tightly staring at the screen of the data. It is a machine that has already made a huge roar in front of him. The heart is in silently praying: must succeed, be sure to succeed ... In this case, this copy is staring at the screen in front of him, Wang Dazhi finally issued all people waiting for the command: "Turn on!

"On!

............................ Chen Geng is shaken by Ding Ruo smoke, usually, no one dares to wake him with him, but today's situation is very different, when Chen Mong When I watched Ding Ruo smoke, he saw an excitement to the extreme face.

"What's wrong? What is so happy?"

I took my eyes and asked Chen Li.

Ding Ruo's excitement: "Wang Dafu just called, our gas turbine trial operation!

"Oh……"

The head is still in a confused Chen Ge, but the next second, his eyes fierce, and there is no trace in the moment of sleep in the eyes: "What do you say ?!

Ding Ruo is too understanding that Chen Mong is in the moment, just, when the babysitter on duty shouted himself, he couldn't excite it. He nodded: "You have not heard the wrong, our gas turbine will be successful. !

"The trial operation is successful? Really?"

"Really,"

Ding Ruo's nods: "You didn't call Wang Dazhi before he slept last night, and he must tell you after the result is coming out.

The third test of the RB211 gas turbine integrity, such a big thing, Chen Li is of course highly concerned, just because of the time difference between China and the United States, it is already five in the morning after the test is completed, take into account the next day to go to the Municipal Government "Sitting"

, Chen Geong had to repeat Wang Da Zhi. After coming out, I must tell myself in the first time - of course, if the results are not so satisfied, don't tell yourself, after all, call yourself and listen to bad news, or let People are very annoyed.

"So, the test is very smooth?"

When the face is looking forward to, Ding Ruo smoke, Chen Li asked carefully.

"very smooth,"

Ding Ruo cigarette did not stop: "It is very smooth, Ignore once once, after Ignition, the whole machine trial runs for half an hour, and the whole system is good. Now Wang Dazhi has turned off, and it is checking the various parts of the system. If the problem, the next step is 10 hours for 10 hours, and the 150-hour trial operation for 150 hours. As long as 150 hours of trial operation, it can be officially entered into the national test stage. Wang Da Zhi said that he has a test of the next test. confidence.

When I said, Ding Ruo couldn't control myself, happy jumping up, as a Chinese man, she felt happy to break the country in the core technical field once again broke the blocked foreign sealing.

The RB211 gas turbine of Shangfei Group is a national key project. After the first trial operation is successful, according to the standard, it is necessary to carry out 10 hours and 20 hours of trial operation, which is called "factory test" for 150 hours.

Stage, when "factory test"

After the end of the stage, it will be officially entered into the national test stage, and only the national test will be officially obtained, and the model certificate and mass production license will be officially got to enter the mass production.

Of course, as special materials in the country, although this gas turbine is working together by many units in the United Nations in the United Nations, it is not that the Shangfei Group has been counted, only through the national approval Row - This is also a world example. For example, our country wants to purchase the LM2500 gas turbine group from General Power, it is not the case after consultation with General Power Company, and must be approved by the US government - as for the reasons, very simple This stuff belongs to the national key controlled strategic strategic material, strategic grade technology, belongs to "waisto"

Level baby.

Since I have a "strategy"

Two words, that is naturally highly controlled by the country.
