![]() ![]() ![]() Technically the term for this engine is the acoustic-type pulsejet, or aerodynamically valved pulsejet. The second type of pulsejet is known as the valveless pulsejet. When the air-fuel is ignited, these valves slam shut, which means that the hot gases can only leave through the engine's tailpipe, thus creating forward thrust. ![]() The first is known as a valved or traditional pulsejet and it has a set of one-way valves through which the incoming air passes. There are two main types of pulsejet engines, both of which use resonant combustion and harness the expanding combustion products to form a pulsating exhaust jet that produces thrust intermittently. Pulsejet engines are a lightweight form of jet propulsion, but usually have a poor compression ratio, and hence give a low specific impulse. it does not need to have air forced into its inlet, typically by forward motion). A pulsejet engine can be made with few or no moving parts, and is capable of running statically (i.e. A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in pulses. ![]()
