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.[2] An annular combustor is featured.

The FJ33 has a dry weight of less than Script error: No such module "convert"., overall diameter of Script error: No such module "convert"., Script error: No such module "convert". overall length, and produces between Script error: No such module "convert". and Script error: No such module "convert". static thrust. Specific fuel consumption at Script error: No such module "convert". thrust (SLS, ISA) is understood to be Script error: No such module "convert"..
