The design and analysis of the National Aerospace Plane (NASP) depends heavily on developing critical technology areas through the Technology Maturation Program (TMP). The TMP is being completed almost entirely in government laboratories with technology dissemination to all prime NASP contractors immediately upon completion of any portion of the technology development. These critical technology areas span the entire engineering design of the vehicle; included are structures, materials, propulsion systems, propellants, propulsion/airframe integration, controls, subsystems, and aerodynamics areas. There is currently a heavy dependence on Computational Fluid Dynamics (CFD) for verification of many of the classical engineering tools. Quite often the design of an aircraft uses wind tunnel tests for much of this verification, but for NASP, this task is almost impossible from a practical standpoint.
