Heat transfer and forces on a blunted 70 deg half angle cone measured in hypersonic free jet flow

Drag, lift, global heat transfer, and recovery temperature are determined on a 70 deg half angle blunted cone which serves as a generic aeroassisted space transfer vehicle (ASTV) configuration. The measurements are performed in a nitrogen free jet flow from continuum to near free molecular flow at stagnation temperatures of T_0=300 K and 500 K and angles of attack #alpha#=0, 20, and 40 deg. The results show mostly the expected smooth transition from continuum to free molecular values for complete accommodation except the heat transfer and recovery temperature data for T_0=500 K, which indicate incomplete accommodation especially of the rotational degrees of freedom on the Cu cone at wall temperatures above 500 K.
