초록

An apparatus for generating power from a trailing vortex induced at the wingtip of an aircraft. A turbine is mounted on the wingtip and is disposed in the trailing vortex. The turbine includes propeller blades extending generally parallel to the axial component of the vorted velocity of the vortex to utilize substantially only the radial component of the vorted velocity of the vortex to thereby reduce the vortex strength and decrease wing drag. The turbine is coupled to an operative system of the aircraft for providing power to the system from the turbin...
