1. Investment needs to be cautious
2. It feels like you're talking about a pattern plate. I suggest you don't invest
3.
During the development period of aircraft engine, it can be regarded as aeroengine technology, but after it is finalized and put into proction, it can be regarded as aeroengine power{ RRRRR}
4. It should be pulse aeroengine
so-called pulse engine. It is a kind of rocket engine. Some people have classified it into the category of jet engine, but most scholars have classified it into the category of rocket engine
the earliest practical rocket pulse engine was a German V-1 cruise missile using kerosene. After the end of World War II, both the Soviet Union and the United States obtained the design drawings and technicians of this engine. However, e to the technical limitations at that time, the thermal efficiency of this engine was not as good as that of turbojet engine, so there was no development< The working principle of pulse jet engine is tempering vacuum pumping cycle. In the combustion chamber, after the mixture is ignited for the first time, it begins to burn violently, and its energy is released from the tail nozzle. During the release process, a low-pressure vacuum is formed in the combustion chamber, and the fuel injection port at the top of the combustion chamber injects atomized fuel into the combustion chamber because of the pressure. At this time, the fuel at the tail of the combustion chamber is still burning, and the pressure at the tail is greater than that in the combustion chamber, So a part of the flame rushes back into the combustion chamber and ignites the newly injected atomized fuel again. The work cycle is like this
take another example in our daily life: when the natural gas stove in our home is ignited, turn it off
and when it is about to be closed, the mouth of the stove will burst, and the flame will suddenly burn violently, and then go out. This is pulse tempering. As long as the flame is not completely extinguished and the fuel is added again, the pulse combustion cycle will occur. It's a pulse rocket engine.

5. Considering the working efficiency and safety factor, thermal power is the first choice. The most important index of aircraft is weight. If electric power is used instead of thermal power, it will need a large output of electric power system. The volume and weight are very large. In addition, the output is difficult to guarantee. Small aircraft and unmanned aerial vehicles can consider using only electric power
however, APU (auxiliary power equipment) is usually installed on the aircraft, which can provide stable power support for the airborne equipment. After all, the flight control system and other systems on the aircraft ultimately need electricity! But the power source of APU is from the thermal power provided by the engine.
