托锥作为一种精度较高的测量系统,在现代飞机的空速校准试飞中有广泛地应用,其也应用在ARJ21机型的空速校准试飞试验。该文介绍了ARJ21机型的空速校准试飞试验,归纳了托锥的实际使用情况,对传感器校准、托锥选型等方面的注意事项进行了总结,认为托锥法可作为空速校准合格审定试飞中表明符合性的有效方法。
Torque cone as a high accuracy measurement system has been widely used in airspeed calibration test of modern aircraft. It is also applied to the airspeed calibration test of the ARJ21. This paper introduces airspeed calibration test flight test of ARJ21 model, summarizes the actual use of toroid, summarizes the precautions in sensor calibration, cone selection and so on. It is concluded that the torch method can be qualified as airspeed calibration An effective method of demonstrating compliance in a validation flight.
