THE CO-TURBOJET ENGINE: A NOVEL CONCEPT FOR MILTI-SPOOL TURBOJET ENGINES [PDF]
International Conference on Aerospace Sciences and Aviation Technology, 1985 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 ...
