This is also a mapping imitation fighter. During the test flight, there were so many problems because the level of materials could not be reached. The new development of the raptor in history was even more an epic battle. Only the medium speed glide was carried out more than 80 times, and the high-speed glide seriously delayed the progress.

Now, the problems exposed by the experiment make many people sink.

Generally speaking, pilots need special restaurants. After all, flying is a sacred profession, and pilots' diet is also very particular.

In the army, the food allowance of pilots is only lower than that of submarine soldiers. Compared with pilots, submarine soldiers are the loneliest and most dangerous arms in the world.

However, in 6611 Institute, Chen Rui is not so particular. After all, this is not a special flight force, so he doesn't make a special one. Eating with everyone makes it more lively.

Tonight, the atmosphere in the canteen was a little depressed.

It's not longer than the runway and frustrating.

If the runway is not long enough, you can find a way, even if it is transported to the test flight yard, but now, the plane can't lift the front wheels!

The Raptor prototype has no problem taking off. Then, where is the problem with our own aircraft?

Is it because some of the parts used by our party are different from the original, resulting in the change of the center of gravity of the whole machine?

The efficiency of the aircraft's rudder is not enough to lift its nose?

Or is it because you have replaced the Spey engine, which is not powerful enough?

If the plane can't even lift its nose, the plane can't fly at all!

Chen Rui is also randomly picking up the rice. While picking up the rice, he thinks that this problem may be very complex or simple.

Don't doubt that the plane has major mechanical problems. After all, the original plane flies very smoothly. Now the plane doesn't raise its head. It must have additional torque.

Is it?

Chen Rui suddenly thought of something, but this is just his own guess. Why don't he try again tomorrow?

Thinking of this, Chen Rui said, "Mr. Song, why don't we do another test flight tomorrow?"

Old song frowned: "fly again? That's what it looks like now."

"Our test flight today is late. Maybe our high-speed camera doesn't shoot very clearly. When the light is good tomorrow, we'll fly again, and then observe the picture of the camera to find out what the problem is."

Hearing Chen Rui's words, old song nodded: "yes, we should fly again and study it carefully."

The human naked eye is not as reliable as the camera, but the high-speed camera is used to record the take-off process. If you carefully study the playback picture, you may find something.

After dinner, Mr. Song and others didn't sleep. They recalculated the data in the hope of finding something.

When the fish belly was white in the East, old song rubbed his sour eyes.

I'm old and lack of energy. I figured it out all night yesterday. I still think there's no problem. The plane should be able to get up easily!

In the duck layout, the rudder surface is in front, and the nose can be lifted directly. When the speed is 100, the torque is large enough. Where is the problem?

Fly again today, and then watch the video. You must find problems.

Old song secretly made up his mind. Yes, there are more ways than difficulties. We must solve these problems!

Old song was full of expectations.

Chen Rui has a good rest. As a pilot, if he doesn't have a good sleep, he can't ensure the safety of flight.

Now, he sat in the cockpit again. After a few days, he found that he had feelings for the unpainted fighter. When he went to bed every night, he was thinking about the plane.

Different from the previous, this is a third-generation aircraft, and it is completely built by our own technical force. If it can succeed, it will enable the Han air force to quickly transition to the sequence of third-generation aircraft and better protect the sky of the motherland.

Chen Rui is looking forward to it.

"The ghost reported to the tower that the engine started normally and asked for high-speed taxiing." Chen Rui shouted on the radio. At this time, the Spey engine at the tail was still roaring.

"Yes, the high-speed camera is in place. Pay attention, slide to the 100 rear lever, and then brake."

Yesterday's test flight has failed, so today we don't expect it to pull up the front wheel. We just hope that today's test flight can provide more data for our own analysis.

"Ghost received." Chen Rui gently pulled the accelerator lever. The Spey engine at the tail continued to roar and release the brake. As yesterday, the plane began to accelerate on the runway.

The airspeed meter quickly pointed to 100. Yesterday, Chen Rui had pulled the lever, but today, he didn't.

Chen Rui's left hand quickly pushed the engine to the idle state, the roar of the tail quickly reduced, and the flame from the nozzle became dim.

However, the fighter is still accelerating. When the pointer is toward 110, Chen Rui's right hand pulls the operating lever and holds it to his chest.

At this time, all the rudder surfaces of the front canard wing and the rear main wing are rotating, relying on the automatic control of the computer to understand the pilot's intention, and then the front wheels are lifted up easily.

Yes, the front wheels are up!

The black front wheel left the runway during the taxiing, and the whole fighter also rose up, raised its nose, and the air inlet in the abdomen was so clearly visible.

At this time, old song immediately opened his mouth in surprise. What's going on? I have got up.

The commander of the tower also shouted in surprise: "ghost, what's the matter? The front wheels have been raised? What's the matter with your engine?"

From the direction of the tower, you can see that the flame of the Raptor's engine is dim and the obvious idle state. At this time, the nose is up?

When the head of the plane was raised, Chen Rui felt that his body began to float. At this time, if he continued to increase the thrust and slide, maybe the plane could really take off.

The plane is ready to fly.

Of course, Chen Rui won't fly it. After all, the test flight should follow the scientific law step by step, and now he must brake.

In fact, when the voice from the tower came from the radio, Chen Rui began to slow down and brake. The runway was too short. If he didn't brake quickly, he might have to rush out of the runway.

The problem that bothered song Laoyi all night has been solved by Chen Rui!

How did Chen Rui do it?
