초록

An engine system with a multi-gas-generator, tip-turbine driven lift fan with pressurized air circulation control for use on vertical and short-take-off and landing (V/STOL) aircraft is disclosed. Gas generators located around the periphery of the fan drive the fan through action on a fan blade-tip turbine or provide compressed gas (hot or cold) to circulation control devices. Variable pitch fan blades improve part-power cruise performance. Enclosed in a nacelle, the engine employs circulation control to enhance V/STOL performance. In some embodiments, a...

청구항

1. An engine system for vertical takeoff and landing (VTOL) aircraft comprising: a fan comprising a plurality of blades and having an axis of rotation, the fan providing at least horizontal thrust;at least one gas generator disposed relative to the plurality of blades so that exhaust gas exits from the at least one gas generator in a direction substantially parallel to the axis of rotation and that impinges on the plurality of blades to generate rotational energy;a nacelle, the fan and the at least one gas generator are disposed in the nacelle, the nacel...
