What is the pulse jet engine used for?
They have been used to power model aircraft, experimental go-karts, and unmanned military aircraft such as cruise missiles and target drones. Working mechanism of a valveless pulsejet engine. The basic idea is that the column of air in the long exhaust pipe functions like the piston of a reciprocating engine. Pulsejets are used today in target drone aircraft, flying control line model aircraft (as well as radio-controlled aircraft), fog generators, and industrial drying and home heating equipment.
