Pulsejet - Wikipedia
网页Pulsejet engines are a lightweight form of jet propulsion, but usually have a poor compression ratio, and hence give a low specific impulse. The two main types of pulsejet engines use resonant combustion and harness the combustion products to form a pulsating exhaust jet that intermittently produces thrust.
jet engine - What are the pros and cons of a pulsejet? - Aviation …
网页2019年11月12日 · The pulse jet engine works because it uses the dynamic pressure of air for compression. Consequently, it needs speed to work well. If the pulse jet is on the ground, it is not easy to start - it needs to be fed with compressed air, and once it runs (it can run even when not moving because the oscillating pressure wave inside the tube will ...
Valveless pulsejet - Wikipedia
网页A pulsejet engine is an air-breathing reaction engine that employs an ongoing sequence of discrete combustion events rather than one sustained combustion event. This clearly distinguishes it from other reaction engine types such as rockets, turbojets, and ramjets, which are all constant combustion devices. All …

How does a pulse jet engine work - Thermal Engineering
网页2024年5月25日 · Pulse jet engines are a type of jet engine that uses pulses of combustion instead of continuous combustion to generate thrust. This simplistic yet efficient mechanism can be explained by several key components and processes that work in tandem to propel the engine forward.
The Past and Future of the Pulse Jet – Disciples of Flight
网页2017年2月14日 · What if a jet engine could have no moving parts? Aviation history enthusiasts will fondly recall the pulse jet (or pulsejet) engine concept as the answer to this question. With historical roots going back to as early as before powered flight, the pulse jet’s characteristic has remained constant.

网页2016年5月26日 · A pulse jet (or pulsejet) engine is a very simple jet engine, which can be made with a few or no moving parts. It comprises an air intake, a combustion chamber, and an acoustically resonant exhaust pipe.
Pulsejet Engines - SpringerLink
网页2012年1月1日 · The pulsejet engine as an alternative means for generating thrust, via a hot exhaust jet, is introduced. Design considerations and limitations of the valved and valveless pulsejet approaches are discussed. The cyclic wave-based operation of the engine is described, and some mathematical analysis is applied toward performance estimation.
