涡轮螺桨飞机性能试飞换算方法研究

FLIGHT TEST REDUCTION METHODS STUDY OF PERFORMANCE FOR AIRCRAFT WITH TURBO PROPS

涡轮螺桨发动机的无因次性能参数是三个变量的函数。在详细地讨论了涡轮螺桨发动机性能方程中的第三个变量之后，本文叙述了涡轮螺桨飞机的性能试飞换算方法，包括无因次图解法及微分修正量法。最后，简要地讨论了上述两种方法的特点及其适用性。

The“non dimensional”engine performance parameter of turbo propsis a function of three variables.After the“third variable”in the performance equations ofturbo props is discussed in detail,the flight test reduction methods of performance foraircraft with turbo props are described in this paper,including the dimensionless grapmethod and the differential correction method.Finally,the feature and availability of above two methods are briefly discussed.
