the Teledyne CAE F408-CA-400 was developed for such UAVs as the Ryan BQM-145A Peregrine, aerial targets, standoff and cruise missiles in the 4.45 kN (1,000 lb) thrust class. Teledyne Continental Model number was 382-10.
F408 had been also used on the Eclipse 500 prototype.
Development began in 1985.
Its classification was « Bypass turbojet » with a ratio about 0.25.
The engine had a fan stage followed by a mixed-flow compressor, slinger type combustor, and a single-stage turbine. The compressor and fan design drew on CAE’s earlier advanced technology work, while the turbine was similar to that used in Model 373-8B. A major purpose of the bypass feature was to cool the engine skin, which greatly simplified missile engine installation.
The engine first run in 1989.
