Single-circuit turbojet engine (working model)

August 11, 2024 - Reading time: ~1 minute

Another experiment of mine with atmospheric jet engines.

It is very simple, but interesting.

I installed an impeller in the pipe, an injection system (the same butane-propane mixture as for the ramjet, it burns well), and also made a nozzle constriction.

The problem with this first version is the lack of a reliable ignition system. When I light the torch from the nozzle side - it often goes out, the impeller "blows away" the detonating air-fuel mixture.

The solution may be to install several spark plugs or spark gaps, but I like vacuum engines better, so I left this project as is, and do not invest time and resources in it.
