For high Mach number flows, M 4, piston theory has been used to calculate the pressures on the surfaces of a vehicle. In a two-dimensional flow, a perpendicular column of fluid stays intact as it passes over a solid surface. Thus, the pressure at the surface can be calculated assuming the surface were a piston moving into a column of fluid. In this work, piston theory is used to calculate the rigid body forces, moments, and stability derivatives of a hypothetical hypersonic vehicle. Only longitudinal motion is considered in this case and lateral motion will be included in subsequent work.
