Analyzes regarding aviation fuels parameters use on jet engines [PDF]
The properties of the fuels determine the quality of the combustion process and implicitly the performance of the turbojet engine. The optimal heterogeneous combustion process of an aviation fuel is ensured by a stoichiometric ratio (fuel/fuel), a ...

THE CO-TURBOJET ENGINE: A NOVEL CONCEPT FOR MILTI-SPOOL TURBOJET ENGINES [PDF]
The novel feature of the co-turbojet engine is the rotation of tne casing of the. high pressure compressor. This casing co-rotates, at lower speed, with the high pressure rotor of the turbojet engine, hence the name co-turbojet. The compressor casing"derives power from the high pressure air stream passing through the compressor and this power is used ...
