Ojodo Sanji was naturally aware of the plight of the Japanese army at this time, and there was no way to get food. He said: "At least remind the soldiers to pay attention. Don't eat whatever you get. It's best to let the Imperial Association troops taste it first, and then eat it after making sure it's not poisonous..." ,Both the five-jet engine and the five-jet engine are the first aviation engines developed by China. In terms of performance, the five-jet engine is much more powerful than the five-jet engine. can increase more than 30%. However, the life of the 5 jet engine was not good. As soon as the development process was successful, the H-6 was put into use, the H-5 lost the value of continuous improvement and Jet engine-5 can only be transferred to technical reserve. If New China wants to develop its aviation industry, it must have its own aviation engine. Because the starting point is very low, 186 is not greedy and will choose the engine with the lowest technical difficulty to imitate. and it would take ten or eight years to develop its own aircraft engine. Remove the engine. Similarly, he also chose the H-5 as the first simulated jet bomber, he not only wanted to imitate but also improve it, while reducing the weight of the aircraft, while increasing its range and ammunition load, making it a long-range aircraft. long-range bomber in the hands of the Red Air Force. Five-jet engines and five-jet engines are the types with the lowest technical difficulty, there are no other options, there are only them!
