Effect of Hypersonic Speeds

Recently, intense research has gone into the development of planes that can fly at hypersonic speeds, approximately five times or more than the speed of sound. At these speeds the properties of air change radically, especially the rapid increase in temperature (to as much as 2,000°F/1,080°C) associated with the air flowing at such speeds along a plane's surface. There appears to exist an aerodynamic thermal barrier similar to the sound barrier confronted fifty years ago.

Solution treatment of aluminum alloys in aerodynamic heating furnaces: Aerodynamic Heating Furnaces (AHTF) in which air or gas is heated to 932-1292[degrees]F (500-700[degrees]C) without electrical or gas heaters were developed in the former Soviet Union. They were widely used for heat treating aluminum, magnesium and titanium alloys as well as steels.(Heat Treating) (Industrial Heating)
