Turboshaft helicopter engines are indirect-reaction engines, where different devices execute the functions of the thermal machine and mover; here the mover is the rotor. Bypass turbo jet, turbo prop and turbo prop fan engines, where the joined mass of air participates in the creation of the thrust, can be referred to as mixed- reaction engines. Presently within the Army there are both ground and air vehicles using turboshaft engines/transmissions, and many more throughout the DoD force. REFERENCES: 1.

Proposals of the Seventh Framework Programme. in the fi eld of Aeronautics and Air. Transport. Turboshaft engines, on the other hand, convert all of the thermal energy into mechanical power for a shaft, by means of a separate turbine, to drive, for example, a helicopter’s propellers or a compressor or an electric power generator in an auxiliary power unit of an airplane.

Combining a simplified on-board turbo-shaft model with sensor fault diagnostic logic, a model-based sensor fault diagnosis method is proposed. The existing fault diagnosis method for turbo-shaft engine key sensors is mainly based on a double redundancies technique, and this can’t be satisfied in some occasions as lack of judgment.

DESCRIPTION: Advanced turboshaft engines are required to support Army Future Force Rotorcraft (Apache, Black Hawk, ARH, Future Combat System UAVS, etc.). It is anticipated that this will involve new centerline engines with a % reduction in specific fuel consumption (SFC), a % improvement in shaft horsepower to weight, and a %.
the resulting book will explain why the stage works for which this period is best known - those with music by henry purcell (e.g. "king arthur" and "the fairy queen"), are so different from continental stage works, and why the genre on which purcell and dryden worked, and which the latter called "dramatick opera", declined rapidly in the 18th.
