Chapter 1541： Find the reason (1/2)

At this time, the speed of the aircraft was very fast. At high speed, when the front wheel was tripped by the ridge, the nose flipped over, like a big head tripped over.

The belly of the plane was facing the sky, the back of the plane was facing the ground, and the whole plane buckled forward, rubbing out sparks on the ground.

Suddenly, a big stone appeared in front of him. The cockpit cover collided with the big stone, and it was immediately shattered. The test pilot Belyakov in the cockpit looked at the big stone, his pupils widened and his mouth widened. There was only time to make a voice: ”Long live the Soviets!”

The plane did not catch fire.

When the people from the base arrived, nearby villagers had already rushed to watch. They carried water to extinguish the small flames. They looked at the almost disintegrated airframe and the pilots who were hit beyond recognition.

Mikoyan also caught up, his face was ugly, his legs were trembling, and he failed. This time the flight test failed again. What was the reason?

Moreover, it also caught the life of Belyakov.

”Take the plane back, disassemble and study.” Gromov also came up, the muscles on his face jerked, and his eyes showed firmness again.

As test pilots, they are accompanied by danger. When needed, they know that they are dead and have to conduct test flights. This is their mission.

At the beginning, Gromov was like this.

When the plane is on the ground, it can still burn steadily. Why does it suddenly turn off when it is in the air?

This is a problem that must be solved.

They moved quickly. When the engine was returned to the flight test center, they immediately dismantled it, and finally found the reason. In an oil pipe, an icicle that had not completely melted appeared.

”The temperature in the high altitude is low. Almost every one kilometer rises, the temperature will drop by six degrees. When the plane rises to an altitude of three kilometers, the temperature has dropped to zero degrees. In this way, the water in our alcohol begins to solidify.” The reason was finally found out, and it was found at the cost of the test pilot's life.

Experiments on the ground will not cause such problems. Only at high altitude will the fault be revealed. This has become the first problem before everyone.

The flying altitude of the aircraft is very high. The MiG-3 can jump up to 10,000 meters, where there can be dozens of degrees below zero. You use alcohol instead of gasoline. The first problem is that the water inside has solidified and blocked the fuel pipe. ?

There are two solutions.

”On the one hand, we can transform the fuel tank and tubing into heating, so that the internal temperature is higher than zero, so that it can be used normally.” An engineer said.

Fuel tanks and tubing heating have already been applied on a large scale in later generations. Heavy trucks burn diesel oil, and diesel fuel will wax at low temperatures, so low-grade diesel must be used, but this diesel is expensive and is not resistant to burning. So there is a means to heat the fuel tank and fuel pipes, which can burn normal zero diesel.
