英文摘要	A large detonation-driven shock tunnel, named JF12, was developed for exploring hypersonic physics in Institute of Mechanics, Chinese Academy of Sciences. The shock tunnel is capable of duplicating the flight conditions and conducting full-scale or near full-scale model tests, which can make it easy for extrapolation of experimental data to flight. However, in view of the need for high-quality aerothermodynamic measurements in hypersonic shock tunnels, a detailed evaluation of the flowfield uniformity and standard model tests are necessary. In this paper, calibration of the Mach 8 nozzle was first presented. Pitot pressure and stagnation heat transfer data acquired using a Pitot rake were discussed to analyze the nozzle flow uniformity. Besides, a precision built 7-deg sharp cone instrumented with heat gages was used. Corresponding numerical simulations were also conducted for comparison. Results showed that good uniformity was found and a core flow region of approximately 1.8 to 2 m diameter was observed. And heat transfer measurement uncertainty was within 卤10%, which was quite good in hypersonic shock tunnels currently. 漏 2017, American Institute of Aeronautics and Astronautics Inc, AIAA.
