There are many more of them than the supersonic aircraft discussed in the last chapter. Applications include missiles, launch vehicles and entry bodies. A huge effort has been made developing Hypersonic Aerodynamics methods and configurations. This began with missiles, including the intercontinental ballistic missile (ICBM) effort of the 1950s, followed by development work for the Mercury, Gemini and Apollo manned space flight programs. The next major effort was devoted to the Space Shuttle. Work on hypersonics for future entry vehicles and landing of vehicles on other planets continues.

Sketch defining the hypersonic directional stability problem Now, for a high-speed flow, we will assume that the vertical tail is a two-dimensional surface with a constant pressure on each side, so that . We will consider two cases, one supersonic, the other hypersonic.
