Patent ID: 12006032

Abstract:
An apparatus is provided, allowing vertical take-off and landing. The apparatus, a biplane, has a cockpit 1attached to a wings assembly 6 by hinges 3 fixed in the supports 7 of the wings. The cockpit having a limited swing possibility within the wings' support structure. The apparatus has four propellers 9, driven by engines 20, disposed two per wing; forming a quadcopter. The apparatus being managed by a computer 17 disposed in the upper wing, and take off being made with the wings and the engines vertically oriented. The apparatus takes off as a quadcopter, and then transitions to cruise flight by reducing the angle of incidence of the wings. Meanwhile, the cockpit 1 remains in a vertical position, due to its lower center of gravity and due to joints 3, which allow it to rotate relative to the wings assembly 6 through a central open area of the lower wing. Landing is made similarly to a quadcopter.
