  •  There are model pulse jet engines. (7+ / 0-)

    The most popular model pulse jet is the Dyna-Jet.  It is still being made and flown in speed competitions in a class especially for them.  This little video shows all the parts and how it works.  There is only one moving part, the valves.  This uses a petal type valve rather than the vanes used in the V-1 engine, but the principle is exactly the same.  This little engine is unbelievably loud,  just like its full size counterpart.  When I was a kid, we got complaints to the police from more than five miles away about the noise when we flew them on control lines.
