The future air breathing engine for hypersonic flight is Scramjet. As there is no need to carry oxidizer onboard, its specific impulse is higher than any non-air breathing chemical propulsion system. Scramjet has no turbo machines and its working principle follows the thermodynamic Brayton cycle. Initially it needs external assistance to start at supersonic velocity but unlike ramjet engine, the combustion takes place at supersonic speeds. The working principle of scramjet engine includes compression, combustion and expansion processes.
