To improve rarefied aerodynamic predictions, the determination of accommodation coefficients and direct measurement of rarefied aerodynamic forces are crucial. Thus, at Japan Aerospace Exploration Agency, a hypersonic rarefied wind tunnel has been developed for rarefied aerodynamic measurements. In this work, we have utilized both experimental and numerical approaches for rarefied hypersonic aerodynamic measurements, and the measurement schemes have been developed by using pendulous models for accommodation coefficients and for aeroshell aerodynamic characteristics. Consequently, we have successfully demonstrated measurements of accommodation coefficients and rarefied aerodynamic characteristics for an aeroshell.Read More
