"Everyman's Jet Engine" - Why Valveless Pulsejets?
Several experimentors, with several different engine designs, have been able to show that modern
valveless pulsejets are capable of being throttled down to very low power levels (sometimes even to
such a low noise level that shouting is audible!). This requires very accurate acoustic tuning, in
order to maintain resonance at such a low power setting. The idea that pulsejets, and especially
valveless pulsejets, are incapable of low-level running is nothing more than a persistent myth. This
belief may be due to so many engines being built that will run but that are not really fully tuned.
