Abstract: An improvement in torque characteristics is provided for a turboshaft engine of the type having a compressor rotor driven by a gas generator turbine that is mechanically independent of the power turbine. The improvement comprises a rotatable compressor stator casing which is interconnected with the power turbine rotor to allow rotation of the compressor casing in the same direction as the compressor rotor at a lower speed. At reduced output shaft speed, the relative speed between the compressor rotor blades and stator blades is increased for increased gas generator output and hence torque, for a predetermined compressor rotor speed.

Abstract: A gas turbine power plant has a compressor stage and a turbine stage with an annular combustion stage therebetween. Each of the contra-rotatable compressor rotors is connected to one of the contra-rotatable turbine rotors by an elongated hollow cylindrical shaft concentric with an axially extending fixed shaft to form an integral unit. The units are operably connected by differential gearing mounted on the fixed shaft just in rear of the nose of the engine at the air intake end of the housing.
