## Abstract

Two force balance techniques for use in hypersonic impulse facilities are compared by measuring the drag force on a $30^o$ semi-apex-angle blunt cone model in a hypersonic shock tunnel at a free stream Mach number of 5.75. An accelerometer-based balance and a stress-wave force balance were tested simultaneously on the same model to measure the drag force. It was found that drag force measurements could be made using both techniques in a flow with a 450-{\mu}s test period. The measured drag forces compared well with the theoretical values estimated using Newtonian theory.
