초록

A thrust unit for an aircraft having a lift unit for propelling the aircraft in upward flight. The lift unit includes a duct for directing air substantially downwardly, the duct being shaped so that air exhausting from its downstream end is in a stream having substantially the same cross-sectional dimension of the duct at the downstream end, and an air pump disposed for inducing a draught of air through the duct. In use, the draught of air exhausting from the duct can produce an upward thrust and is substantially non-convergent.

청구항

A VTOL aircraft comprising: an airframe; a thrust unit located within the airframe for propelling the VTOL aircraft in a vertical flight mode and a transition flight mode between vertical flight and horizontal flight, the thrust unit having; a) a duct including: an inlet disposed substantially vertically upwardly on an upper surface of the airframe for allowing air into the duct, the inlet having means for inhibiting separation of the air from an outer lip of the inlet for improving the efficiency of operation of the duct, a chamber located below the inl...
