Aerodynamic design of the space shuttle orbiter

An overview of the wind tunnel program is given and aerodynamic characteristics of the final configuration are described. Aerodynamic parameters critical to definition of Orbiter entry control and performance are identified. Trim capability and stability and control characteristics are discussed at critical regions in the entry trajectory. Methods are described to define reaction control rocket effectiveness and aerodynamic interactions during the initial portion of entry. At hypersonic speeds, wind tunnel results of viscous interaction effects at high angles of attack are discussed. In the supersonic region, critical stability and control parameters and wind tunnel results are described. At subsonic speeds, comparisons are shown between predicted aerodynamic characteristics and data from the approach and landing flight test program.
