Abstract—This paper is all about the rocket engine involving the use of cryogenic technology at a cryogenic temperature (123 K). This basically uses the liquid oxygen and liquid hydrogen as an oxidizer and fuel, which are very clean and non-pollutant fuels compared to other hydrocarbon fuels like: Petrol, Diesel, Gasoline, LPG, CNG, etc., sometimes, liquid nitrogen is also used as an fuel. The efficiency of the rocket engine is more than the jet engine. As per the Newton’s third law of mechanics, the thrust produced in rocket engine is outwards whereas that produced in jet engine is inwards.

Index Terms—Rocket engine, Cryogenic technology, Cryogenic temperature, Liquid hydrogen and oxygen, Newtonion’s third law of mechanics
