AERODYNAMIC CHARACTERISTICS OF GENERALIZED BENT BICONIC BODIES FOR AERO-ASSISTED, ORBITAL-TRANSFER VEHICLES Carol B. Davies* Informatics General Corporation, Palo Alto, California and Chul Park't NASA Ames Research Center, Moffett Field, California Abstract A method was developed to generate the surface coordinates of body shapes suitable for aeroassisted, orbital-transfer vehicles (AOTVs) by extending bent biconic geometries. Lift, drag, and longitudinal moments were calculated for the bodies using Newtonian flow theory. These techniques were applied to symmetric and asymmetric aerobraking vehicles, and to an aeromaneuvering vehicle with high LID. Results for aerobraking applications indicate that a
