HYPERSONIC UTILITY GLIDER THERMODYNAMIC ANALYSIS
GENERAL DYNAMICS/ASTRONAUTICS SAN DIEGO CA
Pagination or Media Count:
Heating analyses indicated an ablative type heat shield was necessary for the stagnation regions of the utility glider, i.e. the nose cap, leading edges and bottom surface while the cooler upper surface was adequately protected by a radiative type heat shield. Four configurations of the Multi- Mission Re-entry Vehicle or Utility Glider were analyzed for total heat shield weight. Whereas all four configurations are delta wing glide vehicles, three are very similar in shape while the fourth has a much flater upper surface and a radically curved bottom surface. Primary difference in the first three configurations is the seating arrangement of the occupants. The total heat shield weight for the first three configurations varied from 3616 to 3712 pounds while the fourth configurations heat shield weight was found to be 3179 pounds.
