How does a model jet engine work?
A model jet engine is basically a scaled down jet engine designed in the early fifties. A model jet engine build up consists of a radial compressor at the front end of the engine case which is connected through a shaft to the turbine at the rear end of the engine case. Between the compressor and the turbine is the combustion chamber. Additional components are fuel lines, starter and exhaust nozzle. A model jet engine works the same as its big brother. Air gets sucked in and compressed. In the combustion chamber fuel is sprayed in and an ignitor ignites the mixture. The burning gases expand and blast out through the nozzle creating thrust. High RPMs (a model jet engine spins at app. 165’000 RPM at 100 % power setting) and high temperatures (combustion temp. app. 2000° C and app. 650° C engine exhaust temp.) require high quality material and manufacturing – resulting in high prices, somewhere between 2000 and 4000 Euros. A model engine is started by inducting gas into the combustion cham
