Information About

De Havilland Gyron




The Gyron was Halford's first Axial-flow design, a complete departure from his earlier Centrifugal-flow engines based on Whittle -like designs, the Goblin (H-1) and Ghost (H-2). The Gyron was also one of the first engines designed specifically for Supersonic flight.

The Gyron first ran in 1953. Flight testing of the Gyron took place on a specially modified Short Sperrin bomber, replacing the lower two Rolls-Royce Avon s with the much larger Gyrons.

The Gyron was selected for a number of projects, most notably the Hawker P.1121 (sometimes referred to as the Hurricane) supersonic attack aircraft that was to have been the replacement for the Hawker Hunter . However, this project was eventually cancelled.
