中文摘要	An aerodynamic force and moment measurement was conducted in JF12 long-testduration detonation-driven shock tunnel of Institute of Mechanics, Chinese Academy of Sciences. The test duration of JF12 is 100–130 ms. The nominal Mach number is 7.0 and the exit diameter of the contoured nozzle is 2.5 m. The total enthalpy is 2.5 MJ/kg which duplicates the hypersonic flight conditions of Mach number 7.0 at 35 km altitude. The test model is the standard aerodynamic force model of 10° half-angle sharp cone. The length of the test model is 1500 mm and the weight is 57 kg. The aerodynamic forces were measured with a six-component strain balance. The angles of attack were set to be-5°, 0°, 5°, 10° and 14°, respectively. The experimental results show that in the 100– 130 ms test duration, the signals of strain balance have 3–4 complete vibration cycles. So, the aerodynamic forces and moments can be obtained directly by averaging the signals of balance without acceleration compensation. The force measurement error of repeatability of JF12 is less than 2%. The aerodynamic force coefficients of JF12 are in good agreement with those of conventional hypersonic wind tunnels. For this test model at Mach number 7.0 and total enthalpy of 2.5 MJ/ kg, the real-gas effects on aerodynamic force characteristics are not very evident.
