After standing in front of the engine and chatting for a few words, Lei Yuanhang asked: "Lao Chen, can this engine of yours still sound after several years!" ”

Chen Jinqiang is still very confident in this, when the project was stopped, he deliberately sealed these good engines, although it was put for a few years, but the metal on the engine is special, plus he let people do rust and moisture-proof treatment, it is even more impossible to have anything!

"Lao Lei, I have always treated these engines as if they were treasures, and there is absolutely no problem, but for the sake of insurance, I still have to pull them to try out the car, and the things that must be installed on the plane must not be sloppy!"

"Okay, I'll get ready on the bench of the research institute in a row, Lao Chen, you work hard, and strive to test all these engines within a few days, if it's okay, I'll have people load these engines on the Yunten!"

Chen Jinqiang couldn't help but be a little excited when he heard this, their group of people developed the turbofan 8 in order to do supporting projects for the Yun 10, they spent more than 10 years but did not let the turbofan 8 be installed on the Yun 10, and the turbofan 8 was finally installed where it should be installed after a lapse of six years!

"Lao Lei, although the turbofan 8 is said to be an imitation of JT-3D, in fact, we still use a lot of our own design ideas, so if you want to install the turbofan 8, the engine compartment of the Yun 10 still needs to be changed!"

"Haha, Lao Chen, thanks to your reminder, I really can't see the difference between the two engines after being idle for several years, I always thought that the two engines were the same!"

"You, you, you, you look down on us who are engaged in engines, JT-3D engine in the sixties is an advanced engine, we have the idea of improvement when we surveyed and mapped, after more than ten years of our efforts to make the turbofan 8 is definitely a new engine, although there is a big gap with the current advanced engines in Europe and the United States, but compared with the JT-3D engine, the thrust of the turbofan 8 has been greatly improved, increasing the thrust by 15 percent, while its fuel consumption has been reduced by 5 percent!"

Lei Yuanhang, who heard these data, looked incredulous, he was the deputy chief engineer of Yunshi before, although they were not responsible for the turbofan 8, but he still knew some of the research and development progress of the turbofan 8, but Lei Yuanhang had not heard of these data before, and when he came back to his senses, he stared at Chen Jinqiang with cow eyes, and said with a disbelieving face:

"Lao Chen, I remember that you don't seem to drink, why do you talk in your dreams in the middle of the day!"

Seeing that the other party didn't believe it, Chen Jinqiang said with a wry smile: "Old Lei, you still don't know me, how can I be the one who fires guns with a mouth!" ”

"Why haven't I heard of the two data you just said?"

"These two data are not known to many technicians involved in turbofan 8, let alone you, at that time because of the trial engine test we found out about this situation, but we test several engines to get a lot of data, although we formed a report but only in a few people public, at that time we have not understood why there is such a big gap between thrust and fuel consumption between several engines!

It wasn't until the turbofan 8 was finalized that we figured out that it was caused by the excessive error in the machining accuracy of several impellers in the engine, and at that time we had almost determined the reason but there was no way to re-trial, so we directly entered the stage of small-batch mass production, this time we specially imported the main components of measuring tools from abroad!

At that time, we pulled an engine off the assembly line on the bench for testing, until the sixth offline test, we have been very sure that the previous thrust and fuel consumption difference is caused by the error of impeller accuracy, and we also got the turbofan 8 than JT-3D better data, and when we sent this accurate report to the end of your Yun 10, and then our turbofan 8 was also stopped, I don't know if the report was taken by the leaders to wipe the ass! ”

Lei Yuanhang, who knows something about Chen Jinqiang, still trusts the other party very much, and after listening to the other party's words, he also believes that the two data are true, otherwise the other party would not be able to say it so solemnly, at this time, Lei Yuanhang is not thinking about the truth of the data, but thinking about what will be the benefit of the turbofan 8's thrust increased by 15 percent!

The increase in transportation discretion is certain, so whether the length that was forced to shorten before Yun Shi can be made up in the subsequent manufacturing, and the reduction of fuel consumption will also increase the maximum range of Yun Shi!

The more Lei Yuanhang thought about it, the more excited he became, as long as the turbofan 8 was powerful, he would be able to remove a piece of the engine, and the overall performance of the aircraft could also be improved!

"Lao Chen, you have helped us a lot, let's go, let's go separately to test the engine!"

Chen Jinqiang saw Lei Yuanhang who left in a hurry, as an engine he is most proud of, of course, is that the engine he developed can be accepted and praised...

Aircraft engine on the bench, connection, fixation, ignition have a set of cumbersome processes, the weather in December has been relatively cold, the engine test bench of the large aircraft research institute on the operator is busy with sweat, but they do not have the slightest complaint, and no one complains about tiredness, because they see a turbofan 8 engine successfully test more than anything to make them excited, today this one is the last of the six engines, after more than six hours of work, All the preparations before the ignition of the engine have been completed!

After receiving the report that the preparations had been completed, the commander immediately shouted into the microphone of the radio: "The engine test is ready, please evacuate all the personnel on the test bench quickly, please evacuate all personnel quickly!" ”

With the command of the radio under the bench all the personnel moved, although they knew that the engine test run is not risky, but each test must strictly implement the safety procedures, with the orderly evacuation of personnel, the commander of the test press the ignition red button!

The command tower is about fifty meters away from the test bench, and the waver standing in the tower looks at the motionless engine not far away through the glass, and his face can't help but turn a little pale, thinking that the button is out of order, he pressed the red button again, but the engine still has no response!

The commander who commanded the first few engine tests actually felt that his underwear was soaked with sweat in the winter, and the experienced commander knew very well that the engine test run that had been finalized was generally to test the working conditions, but the engines of this batch of tests were all engines that had been sealed for five or six years, and he was careful about the test run of this batch of engines!

The first few times the commander was ready to personally take people to inspect it, but with the first five successful test runs, he felt that this batch of engines was very normal, so he reduced the inspection procedure for himself, but he didn't expect that the ignition of the last engine was not ignited!
