"Yes, yes, we will definitely catch up!" Professor Zhao is sixty years old, just like a child, his face flushed.

"The most important thing for us now is to complete all kinds of tests on it, especially the safety test of the whole aircraft, etc., my purpose is not to study the engine, I want to design the fighter." Jiang Yanhai said seriously.

"Hahahaha! Okay, don't worry, boy! That's it, you're the engine! Don't brag about it, even if the aerodynamic layout of the fighter you design is not up to par, it can push it into the sky for you! And it can also be a fighter with good overall performance! ”

Professor Zhao said with a happy smile.

"Then you have to pass the test." Jiang Yanhai immediately smiled, what he said was right, the thrust is big enough, and any shape can send you to the sky.

"Okay, don't worry, we'll start testing it for you now." Professor Zhao said with a smile.

Next, Jiang Yanhai can be regarded as seeing the struggle of these scientific researchers, and it can be said that their livers are much better than those programmers who stay up late to program liver programs.

Anyway, this is a private research institute, and the engine test can be carried out without following the usual procedures, and the whole machine can be tested directly, and after the second one is built, some destructive tests can be started, etc.

The long-term test test of the whole machine is not only to test the life of the engine, but also to test the performance of engine components.

For example, the current domestic fighter engine needs to be inspected every 50-100 hours to check the performance of wearing parts, including load-bearing parts, oil filters, oil pumps, etc.

A thousand hours for a major overhaul, and the life of a fighter engine's engine is only 1,800 hours, and in actual use, this life is even lower.

Of course, this is the part that was manufactured before, and at present, after the breakthrough of some materials in China, the overall life of the entire engine after overhaul can reach more than 4000 hours, which is double the previous one.

The engine life of fighter jets in the United States is longer than that in China, and many years ago the other side was able to achieve an overall engine life of 8,000 hours after refurbishment.

If there is a gap, we must admit it, only by recognizing the gap, can we catch up, we can't blindly brag about it, and we can't blindly watch the reports of the three media outlets, there is not much truth.

Weak is weak, but after so many years, we have caught up in so many aspects, not bad for such a thing.

Jiang Yanhai is not easy to say how much the life of the new material of the phantom engine is, because the engine that has not been tested is incomplete, and the specific test can only be carried out when the whole machine is tested, including 150H hours of long-term test and so on.

Anyway, it's just a few engines, how to toss and how to come, how to break how to come. Only if problems are found in the test workshop, there will be no problems when fighters are put on board in the future.

The F119 engine of the F22 can achieve 500,000 hours without accidents, although this is the total data of all fighters combined, but this is also a very strong data, which can prove that Pratt & Whitney Engine Company's technology in this area is indeed a bull.

The Phantom engine test is directly the first item to directly carry out a 150-hour long-term operation test, as for whether it will be broken, no one knows, its fuel consumption is naturally a huge number, but this fuel money for the engine that has been successfully developed, that is drizzle.

Moreover, in order to keep this new type of aviation fuel secret, Li Yunfeng directly bought several refineries, and all the blending was carried out inside his own factory.

So, you don't have to worry about the lack of fuel.

150 hours of long operation, which is a very long time for a fighter, and within these 150 hours, it is not a direct ignition test to let it run all the time, within this 150 hours, it will continue to test its various thrusts at different stages.

Even its vector propulsion, etc., all tests that can be carried out in operation can be carried out.

After two days of engine testing, Jiang Yanhai left here, and when he left, he had already greeted the hounds.

The security level here will go up several steps, and it is estimated that anyone who does not know will approach it directly under scrutiny.

The personnel within the entire research institute are naturally also under surveillance, and for the time being, Jiang Yanhai did not inform Liu Lao of the situation of the engine, not that he was afraid that the results would be occupied or anything like that, with Jiang Yanhai's current status, such a thing could not appear on him.

After all, the first test run of the engine has not ended, and after the 150-hour long test run, you can know what happened to the engine according to the test results.

Even Jiang Yanhai knows its quality and effect, but he always has to wait for it to be tested.

And these test results are essential, and they will be a must when they get on board for actual test flights in the future.

150 hours is just over six days, and he still has to wait for this time, and it sometimes takes more than ten years for a fighter jet to be born from design to final birth, and he has made this fast enough.

On the engine side, let's test it first, and then we can blow the tunnel.

The blowing tunnel is simple, and Jiang Yanhai has all the external modeling data of the entire phantom here, and when he was studying in school during this time, he also watched the J20 that Liu Lao applied for, including the circuit design inside the J10.

In fact, most of the similarities are common, and it is not difficult to design the interior while maintaining the appearance of the Phantom.

At present, this part is designed by Jiang Yanhai himself, after all, the whole appearance is the same, and the internal circuit design, including various electronic equipment and instruments, he still has to make his own arrangements.

Including the internal fuel tank and the special structure with electronic equipment, the design is not an easy job, fortunately, the appearance design Jiang Yanhai has all here.

Electronic warfare systems are a strong point when it comes to calculations and analysis, but that's all he can do to build the Phantom before the Darkblade force is successfully formed.

It may differ from the original Phantom's internal design, but none of this matters, as some of the internal design does not affect its actual performance.

What affects its actual performance is whether the composite material can be made or not.

But that's not in a hurry, first get some of your own design first, for example, the wind tunnel blows first, the engine is tested first, and the design of the phantom is done first, and then the composite material will naturally not be a problem.
