My jet engine is unique. There are actually many no-moving-parts jets. Each with different drawbacks. A ramjet cannot start from a static position, mine can start from a static position.
If anyone is interested, there are some very cool no-moving-parts jets that aren't as well known as ramjets:
The lockwood hiller pulsejet is a pulsejet that doesn't need reed valves.

The Gluhareff Pressure jet is also a neat example. https://en.wikipedia.org/wiki/Gluhareff_Pressure_Jet
