Cryogenic Engines and their Working Mechanisms A Review

Abstract

A cryogenic engine is a liquid propellant engine which uses cryogenic propellants to provide thrust. By changing certain parameters, cryogenic engines of different types can be developed to be used according to the mission requirement. Each engine is unique in its cooling mechanism and nozzle behavior. This article aims to describe various cooling systems and the working mechanism of different cryogenic engines. It also assesses the performance and efficiency of different cryogenic cycles. The sketch of all the working cycles included in this article will give all the necessary information to understand and compare cryogenic system and its components.

Keywords: Engine performance, cooling systems, working mechanism, cycles
