Abstract
Heat-transfer distribution data obtained in the arc-driven tunnels (hotshot type) of the von Karman Gas Dynamics Facility, AEDC, are pre sented. Data were taken on a 9-deg half-angle spherically bluqu 17 and 20 and Reynolds numbers per foot in the free-stream between 100,000 and 800,000. The test data are compared with theory and available shock tube and shock tunnel results. Good agreement between Lees' theory and measured heat-transfer rates demonstrates the capability of the VKF hotshot tunnels to obtain heat-transfer distribution data. The data indicate a strong dependence of the heat-transfer distribution on pressure dis tribution, Mach number, and cone half-angle. The heat-transfer data are correlated over a wide range of Mach numbers and cone angles. Correla tion curves and formulas are presented for the pressure and heat-transfer distribution to spherically blunted cones at hypersonic con ditions.
