Chapter 860 Those People and Things (11000 Monthly Tickets Plus More)
"Yes, yes, we will definitely catch up!" Professor Zhao, who is sixty years old, looks like a child, and his cheeks are flushed.
"The most important thing for us now is to complete its various tests, especially the safety test of the whole machine, etc. My purpose is not to study the engine, I want to design a fighter aircraft." Jiang Yanhai said seriously.
"Hahaha! Okay, kid, don't worry! It's just your engine! Let's not brag, even if the aerodynamic layout of the fighter you designed is not good enough, it can push it to the sky for you! And it can also become a whole. Great fighter!"
Professor Zhao said with a happy smile.
"Then you have to pass the test anyway." Jiang Yanhai laughed immediately, he was right, the thrust is strong enough, and any shape can be sent to the sky for you.
"Okay, don't worry, we'll start testing you now." Professor Zhao said with a smile.
Next, Jiang Yanhai saw the struggle of these scientific researchers. It can be said that they are more aggressive than those programmers who stay up late to program.
Anyway, this is a private research institute. The test of the engine can be done without following the conventional procedures, and the whole machine test can be started directly. After the second one is built, some destructive tests can be started, etc.
The long-term commissioning 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 requires a special inspection every 50-100 hours to check the performance of vulnerable parts including load-bearing parts, oil filters, and oil pumps.
One thousand hours for an overhaul, and the life of a fighter engine is only 1,800 hours. In actual use, this life is even lower.
Of course, this is the part that was manufactured before, but at present, after breakthroughs in certain materials have been made in China, the overall life of the entire engine together with the overhaul can reach more than 4,000 hours, which is doubled compared to before.
The US's fighter jet engine has a longer lifespan than China's. Many years ago, the other party could achieve an overall engine life of 8,000 hours after refurbishment. In this regard, China is far behind the other party, and this is the other party's technology in the last century.
If there is a gap, you must recognize it. Only by recognizing the gap can you catch up. You can't just make fun of it, and you can't blindly read the reports of the third-rate media. There is not much truth.
Weak is weak, but over the years, we have caught up in so many aspects, and it is not less than that.
Jiang Yanhai can't say how long the new material of the Wraith engine will last, because an engine that has not undergone the whole machine test run is incomplete. will be carried out.
Anyway, there are just a few engines, how to get it, how to get it, how to get it. Only if the problem is found in the trial workshop, there will be no problem in the future on the fighter.
The F119 engine of the F22 can achieve 500,000 hours without accidents. Although this is the total data of all fighter jets, it is also a very powerful data, which can prove that Pratt & Whitney Engine Company is indeed a fork in this regard. .
The Phantom engine was tested for a long time for 150 hours. No one knows if it will be damaged. Its fuel consumption is naturally a huge number, but this fuel cost is very important for the successful research and development. For this engine, that's drizzle.
Moreover, in order to keep this new type of aviation fuel secret, Li Yunfeng directly bought several oil refineries, and all the blending was carried out in his own factory.
Therefore, there is no need to worry about the lack of fuel quantity.
150 hours of long-term operation is a very long time for a fighter, and within these 150 hours, it is not directly ignited and tested to keep it running. Within these 150 hours, it will continue to run. Test it with various thrusts in different stages.
Even including its vector propulsion, etc., all tests that can be carried out in operation can be carried out.
Two days after the engine test drive, Jiang Yanhai left from here. When he left, he had already greeted the hound.
The security level here will rise several steps, and it is estimated that anyone who does not know approaching will be directly reviewed.
The personnel in the entire research institute are naturally under monitoring. For the time being, Jiang Yanhai did not inform Mr. Liu and the others about the situation of the engine. It was not because he was afraid that the results would be occupied by others, and things like Jiang Yanhai's current status would not be the case. may appear on him.
But after all, the first test run of the engine has not yet ended. After the 150-hour long test run is over, you can know how the engine is going according to the test results.
Even if Jiang Yanhai knew its quality and effect, he always had to wait for the test to come out.
And these test results are essential, and it will be a must when we board the aircraft for actual test flights in the future.
150 hours is just more than six days. He can still wait at this time. From design to final birth of a fighter jet, it sometimes takes more than ten years to be born, and he has already achieved this speed. Fast enough.
Let the engine be tested first, and then you can blow the hole.
The blowing hole is simple. Jiang Yanhai has all the external modeling data of the entire Phantom here, and when he was studying in the school during this time, he also watched the J20 that Mr. Liu applied for, including the circuit design inside the J10.
In fact, most of them have the same purpose, and in the case of maintaining the shape of the Phantom, it is not difficult to design the interior.
At present, this part is designed by Jiang Yanhai, who is sturdy and solid. After all, the whole shape is the same, and the internal circuit design, including various electronic equipment and instruments, he still has to make his own arrangements.
Including the special structure of the internal fuel tank and the electronic equipment, the design is not an easy task. Fortunately, Jiang Yanhai has all the appearance designs here.
As for the calculation and analysis, the electronic warfare system is a strong point, but that's all, it would be good for him to be able to build the Phantom before the successful formation of the dark blade force.
It may be different from the original Wraith's internal design, but these are not important, and some of the internal design does not affect its actual performance.
What affects its actual performance is what the composite material can do.
But I can't be in a hurry. I will work out some of my own designs first. For example, the wind tunnel will blow first, the engine will be tested first, and the design of the Phantom will be developed first, and then the composite material will naturally not be a problem.
