The principle

This simplified cutaway allows beginners to familiarise themselves with the special terms relating to the various parts.

 

Put simply: Air is sucked in by the compressor (approximately 170  litres per second with the gas at full throttle), goes past the outside of the diffuser and then enters the combustion chamber in a pressurised state, via the carefully-positioned holes. It then mixes with the kerosene arriving via the injectors (not shown) inserted in the sticks, creating distinct flames which are curled around inside the chamber.

The hot air is ejected via the rear wheel by entraining it as part of its rotation. The rpm level is controlled using an electronic system which controls an injection pump whilst taking into account both temperature fluctuations and the revolutions speed, which is controlled either by a Hall effect sensor or by infrared diodes.
