U.S. patent 1,655,113 - Method of Aerial Transportation - 1928 January 3 - VTOL aeroplane; Describes a method of achieved vertical take-off, transition to and from horizontal flight, and vertical landing, with a tilting rotor. Including transportation which consists in developing by the propelling device a vertical thrust in excess of the normal, causing thereby the machine to rise in an approximately vertical direction, tilting it and simultaneously increasing the power of the motor and thereby the propeller thrust, then gradually reducing the propeller thrust as forward speed is gained and the plane takes up the load, thus maintaining the lifting force sensibly constant during flight, tilting the machine back to its original position and at the same time increasing the power if the motor and thrust of the propeller and effecting a landing under the restraining action of the same.
