At this time, the speed of the aircraft is very fast. At high speed, when the front wheel stumbles on the ridge, the nose turns over in an instant, just like a big head stumbles.
The belly of the aircraft was facing the sky and the back of the aircraft was facing the ground. The whole aircraft slid backwards and rubbed out sparks with the ground.
Suddenly, a big stone appeared in front. The cockpit cover collided with the big stone and was immediately smashed. The test pilot beliyakov in the cockpit looked at the big stone, his pupils widened, and only had time to make a voice: "long live the Soviet!"
The plane didn't catch fire.
When the personnel in the base arrived, the nearby villagers had come to watch. They carried water and put out the small flames of friction. They looked at the almost disintegrated body and the pilot who was knocked beyond recognition.
Michael Yang also caught up. His face was ugly. His legs trembled and failed. The test flight failed again. What was the reason?
Moreover, it also took the life of beliyakov.
"Take the plane back and disassemble it for research." Gromov also came up, the muscles on his face trembled, and then his eyes showed firmness again.
As test pilots, they are accompanied by danger. When necessary, they know they are dead and have to test fly. This is their mission.
At first, Gromov was such a person.
The plane can burn steadily on the ground. Why does it suddenly stop when it reaches the air?
This is a problem that must be solved.
They moved quickly. When the engine was sent back to the flight test yard, it was disassembled immediately. Finally, the reason was found. An ice column that had not completely melted appeared in an oil pipe.
"The high air temperature is low. The temperature will drop by six degrees almost every kilometer. When the plane rises to 3000 meters, the temperature has dropped to zero. In this way, the water in our alcohol begins to solidify." This reason was finally found out at the cost of the test pilot's life.
(from Baidu, according to this calculation, the temperature on Mount Everest will be tens of degrees below zero?)
In the experiment on the ground, there will be no such problem. Only at high altitude will the fault be displayed, which has become the first problem in front of everyone.
The flight altitude of the aircraft is very high. Mig-3 can jump up to 10000 meters. There can be tens of degrees below zero. Our side uses alcohol instead of gasoline. The first problem is that the water in it solidifies and blocks the oil pipe. What should we do?
There are two solutions.
"On the one hand, we can transform the oil tank and oil pipe into a heated one to make its internal temperature higher than zero, so that it can be used normally." Said one engineer.
Oil tank and oil pipe heating have been applied on a large scale in future generations. Heavy trucks burn diesel, and diesel will wax at low temperature. Low grade diesel must be used, but this kind of diesel is expensive and is not resistant to combustion. Therefore, the means of heating oil tank and oil pipe appears to burn normal No. 0 diesel.
It's not difficult to say. It's OK to change it to electric heating. However, in practice, there will be problems.
Electricity on the plane is precious, and electric heating consumes a lot of electricity. What's more, their fuel is alcohol. Once there is any fault, it may catch fire directly.
Moreover, it will also cause the complexity of the internal structure. They want to make major changes to the existing aircraft, including the transformation of all fuel tanks and oil pipes, but it is not a small amount of work.
Therefore, everyone shook their heads when they heard this plan, which is not in line with the current needs. What they want is to make small changes to the aircraft. It's best to replace it without changing. It's definitely not that they almost need to disassemble the aircraft and replace the heating oil tank and heating oil pipe.
This is not appropriate.
"Another solution is to improve the purity of alcohol and make the alcohol content higher than 99.9 percent."
Since it is inconvenient to heat the oil pipe of the oil tank, find a way to improve the fuel purity.
Several tons of vodka have been consumed, but vodka with a purity of only 95 still can't. just continue to increase the purity so that it is almost all pure alcohol.
In this way, the water content in it is quite scarce. Even if it solidifies in the high altitude, it will not block the oil pipe. After entering the carburetor, it is close to the engine, and the heat of the engine itself is enough to melt it.
Improve the purity of fuel! Hearing this suggestion, Michael Yang nodded: "this is a feasible scheme. Give the task to the winery and let them find a way to meet our requirements."
"In addition, according to the recording equipment on the aircraft and Comrade beliyakov's report during the test flight, we found that the power of the aircraft began to decline significantly with the continuous climb. We calculated that the calorific value of alcohol is smaller than that of gasoline. In order to get more power for the aircraft, we need to adjust the fuel volume, Let more alcohol enter the cylinder for combustion. "
Soviet aircraft designers found the right plan.
The use of alcohol instead of gasoline has also happened in history, that is, in the northeast of China, it was just liberated at that time and obtained a number of aircraft from island countries, but there was no gasoline. In order to train Huaxia's own pilots as soon as possible, At that time, Comrade Zhu Rui, leader of the aviation corps, provided Comrade Jiang natural, Deputy Education Director of the aviation school, with a top secret information of the Japanese army and more than a dozen barrels of alcohol for test.
At that time, the islanders did not succeed in the experiment of replacing aviation gasoline with alcohol. The main reason was that they stopped in the air and killed 31 people in the experiment. After reporting this situation to school leaders Chang Qiankun, Wang Bi and other comrades, Jiang Tianran proposed that China should continue to carry out alcohol substitution test.
After hundreds of tests and analysis, they finally found out the reason for air parking: it turned out that the amount of alcohol released less energy than aviation gasoline. The solution to the problem is to improve the purity of alcohol, transform the engine nozzle and increase the amount of alcohol, so that the heat energy of alcohol combustion is the same as that of gasoline. In the end they succeeded.
In history, the island countries were short of fuel, but the Soviet Union was not short of fuel. But now, the realistic dilemma forced the Soviet Union to change its thinking and find alternative means.
They are replacing gasoline with alcohol, which is their best solution. Now, just when Germany has begun to attack Moscow, they have finally found the right solution.
Only by letting the fighters continue to fly can they fight with the Germans in the air and better protect the land battlefield. Without air control, there is nothing.
Please report us if you find any errors so we can fix it asap!
