Armstrong Whitworth AW.171

The Armstrong Whitworth AW.171 was a British project of the 1950s to develop a supersonic VTOL flying wing aircraft. It was planned to investigate the extremely low aspect ratio delta wings proposed by Professor A.A. Griffith for supersonic transports. The A.W.171 design was a very slender delta flying wing powered by two Bristol Orpheus turbojets mounted at the wingtips, with 10 Rolls-Royce RB.108 lift jets. The pilot was to lie in a prone position to minimise drag.[1] Work was cancelled in 1957 before a prototype was completed.
