Brief history of the jet engine, leading up to the scramjet: Henri Coanda, a Romanian engineer, experimented with a reaction-powered aircraft in 1910, and observed the phenomenon now known as the Coanda effect. In 1939 the English engineer Frank Whittle developed a jet engine that powered a full-sized aircraft, and a year later Secundo Campini in Italy flew for 10 min using a thermal jet engine.
Jet-propelled aircraft have replaced propeller-driven types in all but short-range commercial applications; turboprop planes, in which a propeller is turned by a turbine engine, are used for short-range flights. The SR-71 Blackbird, a U.S. jet spyplane, holds the current speed record of 2,193.17 mph for a piloted air-breathing airplane, but NASA's experimental scramjet-powered pilotless X-43A bested this, almost reaching Mach 7 and Mach 10 in brief test flights in 2004. The Australian-led HyShot Flight Program successfully tested a British-designed scramjet engine in 2006.
