| AFPN) -- For an aircraft to achieve hypersonic speeds, ranging from 6,000 to 15,000 mph (Mach 9 to Mach 22), and reach altitudes between 100,000 to 150,000 feet, it needs an airframe structure designed to survive intense heat and pressure. A: The flight demonstrated that a scramjet engine could fly at hypersonic speeds. The wedge-shaped vehicle, called an X-43A or Hyper-X, separated from its booster rocket and zoomed at a hypersonic speed of seven times the speed of sound--a record for air-breathing jet planes. |
