MANEUVERING REENTRY BODY AEROTHERMAL ANALYSIS COMPUTER PROGRAM

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP AND SUPPLY AN AEROTHERMAL ANALYSIS COMPUTER PROGRAM TO PREDICT SHAPE CHANGE AND INTERNAL DISTRIBUTIONS FOR ADVANCED MANEUVERING REENTRY BODY CONFIGURATIONS. THE TEMPERATURE APPROACH WILL BE TO UPGRADE THE EXISTING MTSCT NOSETIP AND FLAP COMPUTER CODES. THESE CODES WERE DEVELOPED BY TEXTRONDEFENSE SYSTEMS AND GENERAL APPLIED SCIENCE LABORATORIES UNDER AIR FORCE CONTRACT TO DETERMINE ABLATION/EROSION SHAPE CHANGE EFFECTS ON NOSETIPS, HEATSHIELDS, AND CONTROL SURFACES OF MANEUVERING RV-S. THE FOLLOWING TASKS MUST BE ACCOMPLISHED TO ACHIEV THIS OBJECTIVE: (1) WEATHER EROSION EFFECTS MUST BE IMPLEMENTED IN THE CODES; (2) AN INTERNAL CONDUCT ION CAPABILITY MUST BE ADDED, SO THAT IN-DEPTH TEMPERATUREDISTRIBUTIONS CAN BE DETERMINED; (3) FLOWFIELD AND SHAPE-CHANGE METHODOLOGY MUST BE DEVELOPED AND IMPLEMENTED FOR COMPLEX 3-D LIFTING CONFIGURATIONS INCLUDING LIFTING SURFACES AND WINGS.
