失速／尾旋模型自由飞试验的空间设计问题

本文论述了在制定飞机的失速/尾旋模型自由飞试验总体方案时必须充分考虑的空间利用问题之重要性;分析了制约试验空间的诸因素;提出了设计飞行剖面的工程估算方法——其中一些半经验方法之使用效果已为我们的自由飞试验所证实;以我们已成功地进行过的带动力遥控试验机、摇控热气飞艇带飞/投放、飞机带飞/投放的失速/尾旋模型自由飞试验为例,剖析了组成整个飞行剖面的各个飞行阶段之特点和影响因素,并以此为据提出了充分利用自由飞试验空间的一些见解。

The Problems of the Design of Space for Model Free-Flight Stall/Spin Test

The importance of the problem of space utilization is discussed, which must be considered sufficiently when the overall scheme of model free-flight stall/spin tests for aeroplanes is determinded. The factors restricting test space have been analyzed; the engineering estimation methods for the flight-profile design have been put out, in which, the application effects of some semi-empirical methods have been proved by our free-flight tests; on the base of free-flight stall/spin tests of radio controlled powered test vehicle and unpowered models carried/ dropped by radio controlled hot air airship or aeroplane, which have been carried out successfully by us, the particularities and affecting factors of stages constituting the whole flight-profile have been analyzed, and based on this, some opinions for the sufficient utilization of space in free-flight test have been put out.
