摘要

At hypersonic speeds, defined as Mach 5 or higher, the compressive heating generated by a vehicle as it passes though the atmosphere is so intense that the air itself undergoes chemical changes. Such heating would destroy turbine or ramjet engines constructed of any known material. Although a variety of rocket-propelled vehicles have flown at hypersonic speeds (e.g., ballistic missile reentry vehicles, the X-15, and the space shuttle), no air-breathing vehicle until the X-43A has proved capable of sustained hypersonic flight.
