Investigation on aerodynamic characteristics of hypersonic rarefied gas flows has been essential for a variety of situations, such as the Super Low Altitude Test Satellite, earth reentries, or planetary atmospheric entries. At Japan Aerospace Exploration Agency, a 100-mm Hypersonic Rarefied Wind Tunnel(HRWT) has been developed. A 45-degree conical nozzle has been designed in this research, and rarefied hypersonic flows have been successfully generated with a Mach number greater than 10.In addition, an integration system between HRWT measurements and particle simulations has been developed, and this system enables us to improve aerodynamic prediction in hypersonic rarefied flows due to the determination of surface accommodation coefficients.

高超音速稀薄气流的空气动力特性研究对于超低空测试卫星、地球再入或行星大气进入等多种情况至关重要。日本宇宙航空研究开发机构开发了100毫米高超音速稀薄风洞（HRWT）。本研究设计了45度锥形喷管，成功产生了马赫数大于10的稀薄高超声速流。此外，还开发了HRWT测量与粒子模拟的集成系统，该系统使我们能够通过确定表面调节系数来改进高超音速稀薄流的空气动力学预测。
