Abstract

Force measurements using internal balances in a hypersonic shock tunnel are contaminated by inertial forces exerted by model oscillations. It is essential to extract aerodynamic forces from oscillation-contaminated short-period measurement data. This paper proposes an oscillation identification technique method. It was assumed that the inertial forces are exponentially decreasing sinusoidal oscillations, and therefore a parameter-matching technique was applied to identify the oscillation characteristics. This method was verified by applying it to standard HB-2 model measurements.
