Abstract : The design of a sensitive, miniature 3-component watercooled strain gage balance capable of operating in a high temperature environment is described. This balance has been used to measure axial force, normal force and pitching moment in the U. S. Naval Ordnance Laboratory's Hypersonic Research Tunnel at Mach 17 and a stagnation temperature of 4000 F. Ten degree included angle cone models with different nose radii were tested. The axial and pitch forces were on the order of .005 pounds. This report describes the balance used in obtaining the data and the performance of the balance itself. Typical curves have been shown of the axial and pitch forces and pitching moment recorded by the balance for evaluation purposes. (Author)
