Vertical Takeoff and Landing (VTOL) aircraft using Tiltrotor Mechanism

Abstract

A multi rotor is aircraft which generates lift and propulsion by way of one or more powered rotors mounted on rotating engine pods usually at the ends of a fixed wing which drive the shafts transferring power to rotor assemblies mounted on the wingtips. It combines the vertical lift capability of a helicopter with the speed and range of a conventional fixed wing aircraft. For vertical flight, the rotors are angled so the plane of rotation is horizontal, lifting the way a helicopter rotor does. As the aircraft gains speed, the rotors are progressively tilted forward, with the plane of rotation eventually becoming vertical. In this mode the wing provides the lift, and the rotor provides thrust as a propeller.
