Abstract : In support of the development of composite structures for super-orbital re-entry vehicles, a series of vehicle studies and nose cap analyses was conducted. The results of these analyses are presented. A survey of the anticipated range of parameters for super-orbital lifting re-entry vehicles was conducted. For a particular re-entry pattern, vehicle designs were postulated for a range of L/D from 0.5 to 2.0 and W/C(D)A from 50 to 500. Complete trajectories were calculated to provide environmental data for nose cap design. Thermodynamic and structural analyses of ablative-radiative and radiative systems were conducted, leading to the final tungsten-thoria composite structure weight averaged 12.7 lb/sq ft for a peak heating rate of 670 Btu/sq ft sec.
