"Everyman's Jet Engine" - Why Valveless Pulsejets?
Since there are no moving parts, there will be virtually no maintenance throughout the life of a
valveless pulsejet. The only notable exceptions are (1) the possibility of replacing the spark plug
if damaged; and (2) the removal and replacement of the fuel nozzle for cleaning or repair if it ever
becomes fouled with foreign matter or damaged in some way. With minimal care, valveless pulsejets are
the most trouble-free jet powerplants ever designed.
- Essentially zero maintenance for continued operation over its useful life
