CONTROL AND HEAT SHIELD REQUIREMENTS FOR BANK-MODULATED SUPERCIRCULAR ENTRY.
Abstract
Bank modulation for supercircular entry was investigated from a control and heating standpoint. The use of error rates in feedback for pitch and yaw loops rather than inertial rates was shown to produce reaction-jet impulse savings on the order of 80 percent. Heating was investigated for (1) a pointed half cone trimmed at (L/D) max, (2) a blunted half spherecone trimmed at (L/D) max, (3) a blunted half spherecone trimmed at (C)L max-all these with the round side windward - and (4) a delta-winged glider trimmed to give the L/D of configuration (1). These vehicles were considered to have a 12-man payload capacity. The blunted half sphere-cone trimmed at (C)L max required the least heat protection weight. (Author)
