The General Electric CJ805 is a jet engine which was developed by GE Aviation in the late 1950s. A simplified civilian version of the J79 featuring an axial compressor, it was developed in two versions. The basic CJ805-3 was a turbojet and powered the Convair 880, while CJ805-23 (military designation TF35), a turbofan derivative, powered the Convair 990 airliners.
Variants and applications
- Convair 880
- Convair 880-22 : Revised variable inlet guide vane and stator control.
- Convair 880-22M : Increased thrust.
- Flight testing in a Douglas RB-66: Aft-fan variant with a direct drive fan attached to a free-running LP turbine.
- Convair 990
- Intended for the proposed Sud Aviation Caravelle 10A
Only a single Sud Aviation Caravelle intended as a prototype for the US market, was equipped with the CJ805.
