Collection Item Summary:

The Whittle W1X was one of two similar engines, W1X and W1, designed by Sir Frank Whittle and developed by Power Jets, Ltd., in the United Kingdom, during the period 1939-1941. The experimental W1X powered the British Gloster E.28/39 aircraft for taxiing trials in April 1941. During these tests, the aircraft made short, straight hops, causing the W1X to become unofficially the first British turbojet to be airborne. The Gloster E. 28/39 is portrayed in the Keith Ferris mural in the gallery.
