초록

A dual-mode high speed rotorcraft is disclosed which combines the efficiency of a helicopter with the high-speed capability of a fixed wing aircraft. The rotorcraft includes a rotor for propulsion during low-speed flight and hover, which is stopped and locked to function as a fixed wing during a high-speed flight. Also included are a canard and a high-lift tail, which together function to provide substantially all of the lift for the rotorcraft during the transition between low and high-speed flight, so that the rotor may be unloaded while starting and s...

청구항

An aircraft capable of both helicopter-type flight and fixed wing flight, comprising: a fuselage; a rotor/wing comprising a hub located on an upper surface of said fuselage and a plurality of rotor blades extending radially from said hub, said aircraft having a first flight regime during which said hub is rotated by at least one engine, thereby rotating said rotor blades such that they provide lift to enable the aircraft to fly vertically, hover, and fly translationally at relatively low speed, and a second flight regime during which said hub is locked t...
