Abstract : Heat transfer and shadowgraph tests were conducted on several lifting bodies of elliptical cross section and sharp- and blunt-nose shapes to determine heat-transfer distributions and shock wave shapes around the various configurations. The tests were conducted at a nominal Mach number of 10 and free-stream unit Reynolds numbers of 0.31, 1.00, and 2.38 million per foot over an angle-of-attack range from 0 to 60 deg. Selected results of the tests presented in this report indicate slight increases in heat-transfer coefficient caused by increased Reynolds number and nose bluntness. Regions of flow separation are also shown on the leeward side of the models at pitch angles of 15 deg. and above. (Author)
