MEASUREMENTS OF PRESSURE AND LOCAL HEAT TRANSFER ON A 20° CONE AT ANGLES OF ATTACK UP TO 20° FOR A MACH NUMBER OF 4.95

摘要

The heat-transfer rates along the most windward generator of the cone increased with increasing angle of attack. The theories of NACA Technical Notes 4152, 4380, and 4208 were compared with the present data. They provided reasonable predictions of the experimental data when the pressure was determined to the second order (Tech. Rep. No. 5, M.I.T. cone tables) and other local conditions were determined to the first order (Tech. Rep. No. 3, M.I.T., cone tables). Heat transfer was greatest along the most windward generator, 0 = 0°, when the flow was wholly laminar. When transition was observed, the 0 = 30° generator generally showed the highest heat transfer.
