A pulsejet is a type of jet engine that works on the principle of pulsating combustion. It is also commonly referred to as a pulse detonation engine, pulse jet engine, or simply pulse engine. The pulsejet is capable of producing high-speed propulsion by utilizing the energy released from the rapid combustion of fuel mixtures in the engine's combustion chamber. Other synonyms for pulsejet engines may include pulse detonation combustion engines, intermittent combustion engines, shock wave engines, and pulse jet propulsion systems. These terms all refer to the same basic principle of operation, where fuel combustion is used to create high-velocity gases that propel an aircraft or other vehicle.
