Like inventor Sir Frank Whittle, who developed Britain's first jet engine, the Gloster Whittle, Hugh Metcalfe who developed our longest serving surface to air missiles, Lewis "Nick" Nicholson who pioneered supersonic aerodynamics
and Tommy Somerville whose parachute release systems were vital to the glider landings of D-Day.
In those early days of high performance jets, with an industry having only rudimentary knowledge of supersonic aerodynamics
, no computers to help design either airframes or engines, and a wing sweepback design copied from a German jet, it was no surprise that the airframe had very troubling flight characteristics (highlighted when NA's chief test pilot George Welch was killed during a high-speed dive, the first of several crashes), and the engine encountered severe compressor stalls caused by inlet duct curvature.
This greater fuel burn is due to basic physics of supersonic aerodynamics
, and cannot be eliminated with clever design,O Drela said.
