Hypersonic Flight Mach number range is very wide, cross-domain subsonic, Sonic, supersonic 3 stages, before they enter the Hypersonic phase. When aircraft from the dense atmosphere into rarefied atmosphere, great changes in air density will pose great difficulties for aircraft design, so you must br

The Mach number scope of the hypersonic flight is very wide, should step the land subsonically, the velocity, at supersonic 3 stages, could enter hypersonic stage. When the aircraft rushes into the thin atmosphere from the dense atmosphere, the enormous change of the air density will design bringing
