Cryogenic Rocket Engine
Presented By:

Meaning of Cryogenics
In physics, cryogenics is the study of the production of very low temperature(below −150 °C, −238 °F or 123 K) and the behavior of materials at those temperatures .
Cryogenic technology
Cryogenic technology involves the use of rocket propellants at extremely low temperatures.
The combination of liquid oxygen and liquid hydrogen offers the highest energy efficiency for rocket engines that need to produce large amounts of thrust.
Oxygen remains a liquid only at temperatures below minus 183 ° Celsius and hydrogen at below minus 253 ° Celsius.
