doi:10.3969/j.issn.1000-1093.2017.08.025

Abstract

Abstract: A rolling device is developed for the continuous change of model's rolling angle, the improvement of test efficiency and test range in the 0.6 m×0.6 m transonic and supersonic wind tunnel. The designs of rolling device, hollow built-in torque servomotor and the software and hardware of control system are introduced. The key technical problems are analyzed and summarized, and the conclusions are finally validated by a wind tunnel test. The test data shows that the rolling device and the central support of the normal force test, as model's supporting mechanisms, can be used to acquire better repeatable data. Meanwhile, the system has a high level control precision (rolling angle≤±3′), and the engineering reliability of the loads meets the wind tunnel test requirements. Key
