Gluhareff Pressure Jet

It was invented by Eugene Michael Gluhareff, a Russian-American[1] engineer who envisioned it as a power plant for personal helicopters and compact aircraft such as microlights.

Having no moving parts, the engine works by having a coiled pipe in the combustion chamber that superheats the fuel (propane) before being injected into the air-fuel inlet.

In the combustion chamber, the fuel/air mixture ignites and burns, creating thrust as it leaves through the exhaust pipe.

Induction and compression of the fuel/air mixture is done both by the pressure of propane as it is injected, along with the sound waves created by combustion acting on the intake stacks.

[4] Although described as a ram jet, this version heats the fuel within a closed space to create the pressure for injection and compression of the entrained air in a similar manner to the Gluhareff design and is in all fundamental respects a pressure jet of the same type.

The Gluhareff pressure jet operates three acoustically tuned input stages which accelerate and direct air into the combustion chamber where it heats the fuel pressure coil.
