Collection Item Summary:

The CJ610, derived from General Electric's J85 military turbojet engine, powered the majority of the first generation of business jet aircraft during the 1960s and early 1970s. Taking a different course than usual, and to better match its size to then new executive aircraft, this engine resulted from removal of the fan from the larger CF700 turbofan engine. The first model in the series, the CJ610-1, was certificated in late-1961 at 12,700 N (2,850 lb) thrust, and powered the Aero Commander Jet Commander 1121, which first flew in January 1963.

Other CJ610 models powered the Learjet Models 23/24/25/28/29, Hamburger Flugzeugbau HFB 320 (Hansa), and Israel Aircraft Industries Model 1123 Westwind. GE built 2,059 of all models of the CJ610 between 1962 and 1982.

This CJ610-6 engine was certificated in June 1966. Between 1966 and 1976, 808 of this model were manufactured, and powered the Learjet 24B/C/D and Learjet 25/B/C.
