Hearing that the pilot had nothing to do and should be able to fly, Liu Yijiu's inner self-blame was alleviated a lot. ↖

But this test flight still touched him very much, and many things, he found, were not as completely controllable as he thought.

Why is this happening?

Obviously, the Cobra maneuver was completed very well at the beginning, and it stands to reason that the output power of the engine is much stronger than that of the original engine, and there is no problem in completing the Super Cobra maneuver, and the reverse backflip behind also proves this problem.

Yin Qingyuan's feedback was too little.

Only after a thorough examination of the fighter and the wake of the test pilot can we conclude exactly why.

The wounded were transported away by ambulances and helicopters, and the fighters began to be towed back to the assembly workshop for inspection.

"I'm waiting for your explanation, if the explanation is not good, take off this dress of yours myself!" Long Yaohua's cold eyes when he left made Liu Yijiu feel scared for the first time.

Yes, since arriving in this era, he has always been insecure because he knows the changes at the top of the country and the direction of policy inclination, and this insecurity is not because he is afraid, but because things that are too far away cannot be controlled by him, and he instinctively has a sense of worry.

He was never afraid of anyone.

Whether it's the old man, Long Yaohua, Li Yunlong, even Ziyang Zhenren. It's impossible to do anything to him.

The original boss Hua is an obvious example.

And this time, he realized that there are a lot of things. This is the republic of the 80s of the 20 th century, with backward foundations, strict training methods for pilots, insufficient intensity, backward materials and technology, and poor processing and manufacturing technology. Fighter design capabilities are also not good.

Liu Yijiu personally guarded the assembly workshop, and he wanted to know the test results of the fighter as soon as possible, and at the same time. also asked Li Rui to go to the hospital to personally take care of many wounded, just to get the news as soon as possible.

After passing from a coma, Yin Qingyuan was awake several times after being rescued, but each time the time was very short. There is simply no way to effectively express what is going on with the fighter. Time was of the essence. There was no time to report all the situations encountered, and they had to concentrate on maneuvering the fighter plane, otherwise it would be a solution to the plane crash and death.

"Director Liu, you'd better come over and have a look......" When the haggard Liu Yijiu was smoking a cigarette and thinking about where the problem would appear, Zhu Houdao's eyes were also bloodshot.

This accident gave them a wake-up call.

When you are engaged in a project, you must not blindly rush forward, although the engine has flown hundreds of hours at the beginning. However, this engine is different from the original production process.

At the very least, these maneuvers should be performed after flying for dozens of hours.

Where do they know. Liu Yijiu is not worried that the engine will not be able to withstand it, but is worried that the F-14, which has been disassembled and assembled I don't know how many times, will disintegrate!

Originally, he wanted to take the Iraqis to see the flight test again, but Liu Yijiu forgot about the Iraqis in Java because of an accident, and directly asked them to give them the video taken at the scene.

Although the video does not have the shock of watching the scene, it does omit the scene of the last fighter plane losing control, and this video shocked the Iraqis.

wanted to talk to Liu Yijiu in detail, but he couldn't see Liu Yijiu at all.

They are as anxious as ants on a hot pan.

"Nima! And so it was! The F-14 is in vain, and it is not impatient at all! Liu Yijiu looked at the situation in front of him and immediately breathed a sigh of relief.

On the F-14 with the engine disassembled, there are already fine cracks at the joints at the roots of the wings, and even the riveting places with a lot of skin on the fuselage already have small cracks.

Due to the unique aerodynamic design, the F-14 has a higher position of the main load-bearing structure and becomes an upper wing. And because it is a variable swept wing, the wing bearings are strong, the wing roots are thick, and the main landing gear is naturally arranged at the wing roots, but the place where the structural strength of the entire fuselage is the greatest is obviously scrapped because this super maneuverability test is full of cracks.

"This is not necessarily a problem with the F-14 itself, we have disassembled and assembled this fighter many times, and we have also made some modifications to the internal avionics system, and now we are not sure whether this is because the F-14 itself cannot withstand such a huge overload, or because we cannot pass the assembly accuracy of the ......" Zhu Houdao said with some embarrassment.

"It should be the design flaw of the F-14 itself, the maximum level flight speed of this fighter at an altitude of 12,190 meters is only Mach 2.34, and the speed above sea level is only Mach 1.2. Liu Yijiu shook his head, the old beauty is not Soviet.

Moreover, the F-14 fighter itself is a variable sweep wing, the hydraulic system is very complex, when performing super maneuvers, in order to obtain less drag or more lift, the variable sweep wing is constantly changing angles throughout the maneuver.

This can be seen from the wingspan seen from the ground.

If it weren't for Yin Qingyuan's minimization of the wing angle and the maximum wingspan in the final reverse heel upward process, it would have been impossible to complete that maneuver.

"Closer to Mach 2.9, the overload is more than 8g, which is more than double the overload when using the Cobra maneuver, and at the same time nearly 2g more than when the Super Cobra maneuvered...... It is also because of this that the test pilots will have unbearable conditions......"

"Did you communicate with Simon? What does he think? Liu Yijiu suddenly asked Simon Love's attitude.

The qiē in front of them subverted their perception of the F-14, which Liu Yijiu did not know before.

It may be because the Americans discovered these problems that they finally retired this fighter, which did not serve for too long, in the face of strong opposition from the military.

Simon has also seen it, but he has taken some of the numbers and has not yet given an answer...... "Zhu Houdao did not exclude Simon from the conflict with Simon Love this time.

It is necessary to find out what is wrong with this accident as much as possible, otherwise it will be a huge disaster for the entire project, whether it is a copy of the F-14 or the Giant Panda project that Simonlov is modifying with the F-14 as a circle.

"Then continue the analysis!" Liu Yijiu gritted his teeth and said.

If it is true that the F-14 has the hidden danger of heavy dà, imitation things, it will not be of much use.

Of course, if the US military uses it like that, none of these hidden dangers will appear.

The problem is that the republic can't be equipped with as many fighters as the US military - there is no money!

After finishing speaking, Liu Yijiu thought that the engine inspection had not yet been sent to him, so he said to Zhu Houdao, "You and Feng Lun analyze them more, and I will go to see the condition of the engine, if there is no fault in the engine, then the problem lies in the fighter itself." When the time comes, let's analyze whether it is caused by our poor assembly technology or our own design defects, and use the computer to do more analysis, so that the comrades can work hard during this time......"

Although it is likely that the root cause of the problem has been found, it is indeed a big blow to Liu Yijiu.

From the beginning, he was desperate to get his hands on the F-14, because this fighter is a classic for too many people.

Not because it was able to sell for $80 million in this era, but because this fighter was an epoch-making product.

This is the world's first third-generation fighter, and at the same time, it is also the most advanced third-generation fighter, but due to the US government, it was finally retired due to the high cost of maintenance.

The US government has never been afraid of the military burning money, and has always maintained the world's largest aircraft carrier fleet and nuclear submarine force.

The F-14 was originally a carrier-based aircraft, and the F-15 and F-16 of the same era were carrying the flag for the US military for decades to come, and if it was replaced with the F-14 with better performance, it was estimated that it would serve for a longer time. Actually, there is no such thing at all.

Even the variable sweep wing, which the U.S. military has not adopted since the F-14 was decommissioned.

Hurried to the Power Research Institute next to the Taiping Temple Airport, Qi Hai was about to go to Liu Yijiu to report the situation.

On the same day, they dismantled the engine from the fighter plane, pulled it back to the assembly workshop overnight, and began to disassemble it for inspection overnight.

Just got the results.

Compared with the pressure on Zhu Houdao's face, Qi Hai said excitedly to Liu Yijiu very excitedly, "Director Liu, there is no problem with our engine at all!" Although the afterburner is not long, there is no change in the assembly accuracy, and even the impeller of the engine is not a problem......"

"No glitches at all? What about the root of the impeller weld? Did you observe it with a microscope? ”

The corners of Liu Yijiu's mouth twitched.

It seems that a piece of news is confirming that the strength of the F-14 will fail in a supermaneuver that flies at higher speeds and needs to withstand greater overload forces.

Does the F-14 really have a huge hidden danger in terms of structural strength?

If this is really the case, obscured by the advanced aerodynamic layout shape, then where should the imitation project go?

If the above knew the news, Jiang Sen, the new director of the Commission of Science, Technology and Industry for National Defense, would have pinched the handle, and the project would have been discontinued, and there would be absolutely no room for negotiation. Unless they don't report the hidden danger to the higher authorities......
