The Fairey Jet Gyrodyne helicopter has completed successfully its initial flight tests at White Waltham Aerodrome, near Maidenhead, Berkshire. It is the first British helicopter to fly with the rotor driven by tip jets and it has also the largest metal blade rotor.
The Fairey Company, in conjunction with the helicopter branch of Ministry of Supply, has converted the Gyrodyne from its original mechanically driven rotor form to the present configuration. This conversion has been undertaken to test under practical conditions some of the problems associated with tip jet propulsion for helicopters. It is not destined to become a production aircraft.
The Gyrodyne is powered by an Alvis Leonides engine and has a two-bladed rotor. Engine power is used to drive compressors with supply compressed air through hollow rotor blades to tip pressure jets, of Fairey design. In cruising flight the major part of the engine power is transferred to two pusher propellers.
