Design and Fabrication of a Valveless Pulsejet Engine

Pulsejet engines are ideal micro propulsion systems because of their simplicity and low cost of construction to produce thrust and heat for diverse applications. This paper describes the procedure of design and manufacturing of a valveless pulsejet engine. Via fabrication of this engine some good experimental results achieved using the Liquefied Petroleum Gas (LPG); the approximate composition of LPG was ۶۰% butane and ۴۰% propane. Temperature of different parts of the engine was measured, and the maximumobserved temperature was ۴۲۰ °C measured at bottom of combustion chamber. The material used (stainless steel–grade ۳۱۶) for fabrication of this engine was suitable for high temperature use (up to ۴۲۰ °C).
