Do the Pulse Jet and Ramjet Are the Same?

Ramjets differ from pulsejets, which use an intermittent combustion; ramjets employ a continuous combustion process. As speed increases, the efficiency of a ramjet starts to drop as the air temperature in the inlet increases due to compression.

What is a pulse jet used for?

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.

What jet is ramjet?

A ramjet is a variant of an air breathing jet engine that does not include a rotary compressor; rather, it uses the engine's forward motion to compress the incoming air. A ramjet cannot function at zero airspeed and therefore cannot be used to power an aircraft in all phases of flight.
