Iron man's first suit of armor should use the missile's propulsion system-this is inferred from the raw materials he used to make the first suit of armor. The missile's propulsion system is also called power plant, including rocket engine and air jet engine. Commonly used chemical rocket engines carry oxidants and combustibles, which are suitable for missiles flying outside the atmosphere. There are usually solid rocket engines, liquid rocket engines and solid-liquid rocket engines. Air jet engines only carry combustible materials and work on oxygen in the air. They are suitable for flying in the atmosphere and usually include turbojet, turbofan jet and ramjet. Judging from the situation seen in the movie, it is more likely that the first suit of armor will adopt turbojet engine. As for the second and third sets of armor, from the appearance, chemical rocket engines may be used. Turbojet engines are not new. As early as 1930, they were developed by the Englishman Frank? 6? 1 whittle registered a patent. This kind of engine sucks in air, increases the air pressure through the rotation of the turbine, and then mixes the high-pressure airflow with the fuel to ignite, generating high-temperature and high-pressure gas to be discharged from the tail nozzle, thus generating reactive thrust. This kind of engine accelerates quickly, but it consumes a lot of fuel. The structure of chemical rocket engine is simpler. Similar to our holiday "Monkey Crossing the Sky", this kind of engine burns solid or liquid propellant in the combustion chamber and ejects the generated high-temperature and high-pressure gas through the nozzle, thus sending the aircraft into the sky. The chemical rocket engine does not need an air inlet, and because the propellant already contains oxidant, it does not need oxygen in the air to help combustion, so it can fly outside the atmosphere and its volume can be made relatively small.

Iron Man
For Iron Man's flight system, how much fuel can be carried is the most important issue. If the power of Iron Man's flight mainly depends on the chemical fuel stored in the armor, then the amount of fuel required for the round-trip flight from the United States to the Middle East is considerable-the weight of Iron Man itself is not small, otherwise it will not break through its own roof-but the more fuel is stored, the greater the volume and weight of this armor, which will restrict the height and length of flight. Moreover, whether there is enough space in the ultra-thin armor to store these fuels is also a problem. Unless he uses a nuclear rocket engine instead of a chemical rocket engine. It's also possible. After all, he has a small nuclear reactor with him. Nuclear rocket engine converts nuclear energy into heat energy to heat working medium (liquid hydrogen, liquid helium, liquid ammonia, etc.). ), and then through the nozzle to accelerate the discharge, generating thrust, better than the traditional rocket engine performance. This kind of engine already has a prototype, but it has not been put into practical use because of nuclear radiation protection, exhaust pollution and other problems. Judging from the plot in the movie, maybe Stark solved these problems in a cave in the Middle East.
