Development of a new captive trajectory simulation system in the 1.2m transonic wind tunnel

For improving the measuring abilities of the weapons interference and separation testing in the 1.2 meter transonic wind tunnel and satisfying the customers' requirements constantly,a new six-degrees of freedom captive trajectory simulation(CTS) system has been designed in China Aerodynamics Research and Development Center(CARDC).This paper introduces the new CTS systems' construction design and realized technology targets as well as applications.The wind tunnel results show that the new CTS system has several improvements over the old CTS system in many aspects such as increased the movement ranges,productivity the testing efficiency,and the range of testing Mach numbers.
