What is pulse jet reed valve?

A pulse jet reed valve is a crucial component of a pulse jet engine. It is a spring-loaded valve that controls the flow of air and fuel into the combustion chamber. When the engine starts, a pulse of fuel enters the combustion chamber, ignites, and creates high pressure that forces the reed valve to close. This prevents fuel from escaping and also creates a vacuum that draws in fresh air into the chamber. As the pressure drops, the reed valve opens again, allowing another pulse of fuel to enter and ignite. This cycle repeats rapidly, creating thrust that propels the engine forward. The design and placement of the reed valve are critical to achieving optimal engine performance.
