全速度范围内确定飞机气动激波修正量

To determine the shock and position error of an aircraft from supersonic speed to the stall area

简要介绍了 GPS方法确定飞机气动激波修正量的原理和测试技术 ,用该方法确定了 J7L飞机直到失速范围内的气动激波修正量。结果表明 ,采用 GPS法 ,通过平飞加、减速飞行 ,可以获得完整的气动激波修正量曲线。试飞动作量少 ,要求容易满足 ,从而大大提高了效率 ,降低了试飞成本。

The principle and test technique of determining the shock and position error of an aircraft by using method of GPS was introduced briefly. Using this method, the shock and position error from supersonic speed to the stall area of J7L was determined. The results show that using the method of GPS, through level accelerate flight and level decelerate flight, we can get the shock and position error curves fully. It has less flight motions and it is very easy to meet the needs, therefor it raise the efficiency, reduce the flight cost.
