ABSTRACT:
A booster-compressor for a high flow coefficient turboprop aircraft engine increases engine thrust by supercharging the air into the inlet of the gas generating core engine. The flow of supercharged air from the booster-compressor is split between the core engine and the ambient to allow for the use of standard size rotor blades and stator blades and to provide supplemental thrust. The rotor blades are designed as impulse rotors and the stator vanes are arranged in an axially converging annular flowpath in order to limit to a minimum any increase in the static pressure of the supercharged air.
