Abstract: (112 Views) |
Cryogenic rocket technology is of great importance in space science. The use of this technology has improved the design of rockets that make space exploration easier. In addition, the development of this technology has increased the success of complex space missions. Cryogenic technology is a process that uses propellants at cryogenic temperatures in rockets. Cryogenic temperature is set from - 150 degrees Celsius to absolute zero. In this research, the cryogenic rocket engine has been investigated. The cryogenic rocket engine is a type of rocket engine that uses cryogenic fuel and oxidizer, that is, both the fuel and the oxidizer are gases that are liquefied and stored at a very low temperature. In other words, they are kept cold to stay liquid. Liquid propellants play a significant role in the development of this technology. According to the investigations, this technology does not produce any harmful products and does not cause pollution to the environment. Also, cryogenic propellants in the liquid rocket engine have a very high specific impact, which are suitable for use in the upper stage of the rocket and booster stages. From analyzing the results, it is understood that the cryogenic rocket engine with LH2/LOX propellant combination is very suitable for the design of the upper stage of the rocket.
