The derivation of two volumetric efficient high L/D entry vehicles is described. Parametric trades in the areas of aerodynamics and aerothermodynamics are discussed and selected parameters are identified. Alternate modes of vehicle recovery are described and the effect on vehicle design determined. The evolution of the FDL-5 configuration selected for wind tunnel testing is described through the presentation of a series of intermediate configurations.
