Vertical take-off aircraft (1) has first (4) and second (17) lifting mechanism (eg helicopter-type rotors, jets, turboprops) arranged in tandem, either above or outboard of ends (2, 3). Lifting mechanisms (4, 17) are independently tiltable, in multiple directions, by hydraulic rams (11, 13, 14, 16, 24, 26, 27, 29) to manoeuvre aircraft (1). In particular first lifting mechanism (4) may be tilted in the opposite transverse direction to second lifting mechanism (17) so as to alter direction of flight. First lifting mechanism (4) may be tilted by further h...
What I claim as my invention is: 1. An aircraft with a main body, a primary lifting mechanism and a secondary lifting mechanism, which main body has a forward end and an aft end, with the primary lifting mechanism and the secondary lifting mechanism connected to the main body of the aircraft in tandem order, and with the aircraft able to achieve flight by means of upward forces exerted on the main body of the aircraft by the primary lifting mechanism and the secondary lifting mechanism while the primary lifting mechanism and the secondary lifting mechan...
