Chapter 671: Failed

This fault is easy to find, but it made the people present very embarrassed that the development of advanced fighters requires the entire country's industry to follow along. It is quite difficult to develop advanced fighters on a weak industrial basis. of.
However, no matter how many difficulties there are, we must overcome them!
As long as you know where the problem is, there is a solution!
After adjusting again and again, flying again and again, finally, by the afternoon of the next day, the fighter plane was able to move steadily along a straight line!
"It's great, we solved the problem so quickly." Chen Rui got off the plane and said to everyone.
"Yes, the problem of our medium-speed skating has been solved. Now, there is a new problem waiting for us." Said Old Song on the side.
New problem? Chen Rui is very surprised. After running at a medium speed, isn't it time for high speed? What are the problems with this high-speed running?
"Don't worry, Song Lao, just leave it to me." Chen Rui said.
This Raptor has flew by itself, and now it's just running at high speed. What's the obstacle?
Medium-speed taxiing is to determine the problem of correcting deviation, while high-speed taxiing is mainly to determine that the aerodynamic force of the aircraft is indeed consistent with the design value. This requires the experiment of raising the front wheel and then lowering it during the high-speed taxiing phase.
To put it simply, the pull rod raises the head after taxiing to a certain speed. At this time, the aerodynamic force of the aircraft should be able to raise the front wheels. Then push the stick again, and the front wheels of the plane can return to the ground. Then take this aerodynamic parameter back on the airplane and compare it with the data from the wind tunnel to correct the calculation model.
Although this is a fake fighter, for Song Lao, almost all the data are consistent with those developed by his own. What is needed now is to verify it through these specific experiments.
Chen Rui didn't feel any psychological burden. The middle-speed skating was the brake problem, which was different from the original version, but the high-speed skating didn't matter. After all, he had already flown the prototype, so the aerodynamic layout was fine.
"Chen Rui, you haven't calculated the runway length we need." Song Lao said.
The higher the speed, the longer the distance you can run. If you fly directly, that's fine. The question is, the sliding experiment has not been completed yet, who dares to fly?
After finishing lifting the front wheels, the aircraft must be able to steadily raise the front wheels for a period of time to collect data. At the same time, the aircraft also needs to slow down and stop. In this way, the required runway is very long.
The runway of the 1132 factory is far from enough.
How to do?
Song Lao started to worry about this high-speed skating when he was skating at the middle speed.
The runway here is not long enough. If you want to find enough runway, you can only go to the Han Guo Flight Test Research Institute in Hojing to do experiments.
The runway there is long enough.
But in this case, a new problem is faced, how to get the plane over?
In general, they all fly by. The problem is, this aircraft is not capable of flying. In other words, if you want to go, you can only take it apart and transport it from the ground?
This is definitely a big trouble.
"Song Lao, I believe that with the wisdom of all of us, this problem will definitely be solved." Chen Rui said: "The solution is always more difficult than the difficulty. Now, let's test the flight first, and find the problem while flying the test."
Old Song nodded.
The schedule is very tight. If it can fly for the first time before October 1st, it will be of great significance. Now, if this obstacle is not resolved, it will be difficult to achieve.
In particular, our own brakes still use metal brake discs, so the braking distance is long.
While Mr. Song was still worrying about this matter, Chen Rui had already started his first high-speed taxiing experiment.
"The ghost requested a high-speed taxi experiment."
"Yes, the ghost pay attention, the speed is 100, try to lift the wheel, no matter whether it can be lifted, slow down, our runway is not long enough." The commander in the tower said.
High-speed skating and medium-speed skating are followed. The maximum speed of medium-speed skating is the minimum speed of high-speed skating.
Now, we can only start with lifting the wheel.
"Understand." Chen Rui said, flipping the switches in an orderly manner, making preparations before sliding.
Medium-speed taxiing almost depends on the low-speed engine thrust, but high-speed taxiing is not enough. After all, the runway is limited. The shorter the distance for high-speed taxiing to 100 kilometers per hour, the longer the distance left for deceleration. , It must be saved.
"The engine is working normally, request the maximum military thrust state." Chen Rui shouted.
"Yes, maximum military thrust."
In the engine, the maximum thrust state is definitely to open the afterburner, but afterburner is only an emergency state, and when the afterburner is not open, the maximum output state of the engine is the maximum military thrust.
The maximum military thrust of the Spey engine is 54 kilonewtons. Now, when Chen Rui pushed the throttle lever to the head with his left hand, he instantly felt the engine roar in the tail.
In the past few days, just running at a low speed, the Raptors can no longer control their desire to fly. Now that they have reached the maximum military thrust, they are ready to spread their wings and want to fly. It can't hold back.
Chen Rui released the brake.
The tail engine sprayed out lavender flames, and the Raptors with duck-like layout began to accelerate rapidly on the runway. The smooth fuselage was so spectacular in everyone's eyes.
For Chen Rui, a violent push came from his back. This is the feeling that a third-generation aircraft should have.
Chen Rui continued to look at the airspeed indicator from the corner of his eye, and at the same time focused on the runway in front. If the acceleration distance is too long, the deceleration distance will not be enough. He must be fast!
With the roar of the engine, the speedometer is turning rapidly. When it points to 100, it already means that the predetermined speed has been reached.
Chen Rui shouted in the radio: "Speed ​​100, raise the front wheel."
With that said, Chen Rui pulled back the operating lever in his hand. He has done this action countless times. As long as he pulls this way, the nose of the machine should be able to lift up. The previous second-generation machines are no problem. Raptors, that's even more okay.
A speed of 100 is the design speed of the front wheels off the ground.
Everyone on the runway was watching nervously, on the one hand, whether the runway was long enough, on the other hand, whether the wheel was lifted.
In the eyes of everyone's expectation, they saw the front wheel steadily touching the runway, and there was no sign of leaving!
"Slow down, slow down immediately!" The tower commander shouted as the runway ahead was getting shorter and shorter.
If it failed, who would have thought that there is no need to lift the front wheel how far to fly, and now, it can't lift the front wheel at all!
