- Williams FJ33
The
Williams International FJ33 is a family ofturbofan jet engine s intended for use in very light jet aircraft. Sources suggest that the FJ33 is a scaled-down version of the FJ44 engine.Engine configuration is believed to be a single stage fan, with booster stage/s, driven by a 2 stage LP turbine, supercharging a centrifugal HP compressor, driven by a single stage HP turbine. An annular combustor is featured.
The FJ33 has a dry weight of less than convert|300|lb|abbr=on, overall diameter of 21.05in, 47.9in overall length, and produces between 1000 and convert|1800|lbf|abbr=on static thrust. Specific fuel consumption at convert|1200|lbf|abbr=on thrust (SLS, ISA) is understood to be 0.486 lb/h/lbf.
FJ33 versions
The -1, -2 , -3 and -4-A11 are believed to be essentially derated versions of the -4. Presumably the -17M and -18M are throttle pushed versions of the -4, but without any flat-rating to a hot day.
