Design
Engine configuration is a single stage fan, with booster stage, driven by a two-stage LP turbine, supercharging a centrifugal HP compressor, driven by a single stage HP turbine.[3] An annular combustor is featured.
The FJ33 has a dry weight of less than 300 lb (140 kg), overall diameter of 18.36 in (466 mm), 38.43 in (976 mm) overall length, and produces between 1,000 lbf (4,400 N) and 1,800 lbf (8,000 N) static thrust. Specific fuel consumption at 1,200 lbf (5,300 N) thrust (SLS, ISA) is understood to be 0.486 lb/(lbf⋅h) (13.8 g/(kN⋅s)).
