AIRCRAFT FOR VERTICAL FLIGHT AND TRANSITION TO AND FROM HORIZONTAL FLIGHT

摘要

This invention is particularly concerned with an aircraft capable of both horizontal and vertical flight and at any required angle and supported by powered wing-rotors that are rotationally synchronized for stability while producing a desired vertical lift as the aircraft ascends and is propelled forward by means of auxiliary engines, and in addition, means are provided to convert said wing-rotors into stationary wing airfoils for normal horizontal flight at greater speed and reconversion to wing-rotors for vertical landing.
