Super Weapon Swap System

This fault is easy to find, but it makes the people present very sad. The development of advanced fighters requires the industry of the whole country to make progress together. It is very difficult to develop advanced fighters on a weak industrial basis.

However, no matter how many difficulties, we must overcome them!

As long as you know where the problem is, there is a way to solve it!

After adjustment and test flight again and again, finally, the next afternoon, the fighter could move steadily along a straight line!

"It's great that we solved the problem so quickly," Chen Rui said to the people after getting off the plane.

"Yes, we have solved the problem of medium speed skating. Now, there is a new problem waiting for us," said old song.

New questions? Chen Rui is very strange. After running at medium speed, isn't it time for high speed? What's the problem with this high-speed slide?

"Don't worry, Mr. Song, just leave it to me," Chen Rui said.

This Raptor has flown by itself. Now it's just a high-speed slide. What's the obstacle?

Medium speed taxiing is the problem of determining and correcting deviation, while high-speed taxiing is mainly to determine that the aerodynamic force of the aircraft is indeed consistent with the design value, so it is necessary to carry out the experiment of lifting the front wheel and then putting it down in the high-speed taxiing stage.

To put it simply, after taxiing to a certain speed, the pull rod rises. At this time, the aerodynamic force of the aircraft should be able to lift the front wheels. Then push it again, and the front wheels of the plane can return to the ground again. Then the aerodynamic parameters on the aircraft are taken back and compared with the wind tunnel blowing data to modify the calculation model.

Although this is an imitation fighter, for Mr. Song, it is almost consistent with the data developed by his own side. What is needed now is to verify it through these specific experiments.

Chen Rui doesn't feel a psychological burden. The medium speed running is the problem of braking. It's different from the original, but the high-speed running doesn't matter. After all, it's already flown over the prototype, and the pneumatic layout is OK.

"Chen Rui, you haven't calculated the runway length we need," said Song.

The higher the speed, the farther the distance. If you fly directly, it's OK. The problem is, who dares to fly now that the experiment of skiing has not been completed?

After lifting the front wheels, the aircraft should be able to stably lift 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 runway is very long.

The runway of 1132 plant is far from enough.

What should I do?

Song Lao started to worry about this high-speed slide when he was running at a medium speed in front of him.

The runway here is not long enough. If you want to find enough runway, you can only go to the Han flight test and Research Institute in Beijing to do experiments.

The runway there is long enough.

However, in this case, we are faced with a new problem, how to get the plane?

In general, they fly over. The problem is that the plane can't reach the flight ability. In other words, if you want to go over, you can only take it apart and transport it from the ground?

This is definitely a big problem.

"Mr. Song, I believe that with the wisdom of all of us, we can solve this problem." Chen Rui said, "there are always more ways than difficulties. Now, let's test fly first and find problems while testing."

Old song nodded.

The progress is very tight. If we can make the first flight before October 1, it will be of great significance. Now, if this obstacle is not solved, it will be difficult to achieve.

In particular, our brakes still use metal brake discs, which is a long braking distance.

While Mr. Song was still worried about it, Chen Rui had started his first high-speed sliding experiment.

"The ghost asked for a high-speed taxi experiment."

"Yes, ghost, attention, speed 100. Try to lift the wheels. Slow down whether you can lift them or not. Our runway is not long enough," said the commander in the tower.

High speed and medium speed are followed. The maximum speed of medium speed is the minimum speed of high speed.

Now, you can only start with lifting the wheel.

"I see," Chen Rui said, turning the switches in an orderly manner, preparing for taxiing.

Medium speed taxiing is almost enough to rely on the low-speed thrust of the engine, but high-speed taxiing is not enough. After all, the runway is limited. The shorter the distance of high-speed taxiing to 100 km / h, the longer the distance left for deceleration. Therefore, it must be saved.

"The engine works normally and requests the maximum military thrust state," Chen Rui shouted.

"Yes, maximum military thrust."

In the engine, the maximum thrust state must be on afterburner, but afterburner is only an emergency state. When afterburner is not on, the maximum output state of the engine is the maximum military thrust.

The maximum military thrust of Spey engine is 54 kn. Now, when Chen Rui pushes the throttle lever to the head with his left hand, he immediately feels the roar of the engine at the tail.

In the past few days, the Raptors have been unable to control their desire to fly after only low-speed taxiing. Now they have reached the maximum military thrust and are ready to spread their wings to fly. It can't help it.

Chen Ruisong opened the brake.

The tail engine spewed out a lavender flame. The Raptor with duck layout began to accelerate rapidly on the runway. The smooth fuselage was so spectacular in everyone's eyes.

For Chen Rui, there is a strong feeling of pushing his back on his back, which is what the third generation aircraft should feel.

Chen Rui continues to look at the airspeed meter with the rest of his eyes and pays attention to the runway in front. If the acceleration distance is too long, the deceleration distance is not enough. He must be fast!

With the roar of the engine, the speedometer is rotating rapidly. When it points to 100, it represents reaching the predetermined speed.

Chen Rui shouted on the radio, "speed 100, lift the front wheel."

Then Chen Rui pulled back the operating lever in his hand. He had done this action countless times. As long as he pulled it, the nose should be able to lift up. There was no problem with the previous second-generation aircraft, especially the Raptor.

Speed 100 is the design speed of the front wheel off the ground.

Everyone on the runway was watching nervously. On the one hand, they looked at whether the runway was long enough and whether the wheels were lifted.

In the expectation of everyone, I saw that the front wheel was steadily touching the runway, and there was no sign of leaving!

"Slow down, slow down now!" the tower commander shouted as he looked at the runway getting shorter and shorter.

Failed, who would have thought, first do not have to lift the front wheel to fly far, now, it simply can not lift the front wheel!
