Abstract
An experimental study of pulsations characteristics of the zone of flow separation arising at a small airplane- type UAV with a pushing two-blade propeller were carried out. The measurements were done in wind tunnel by unsteady pressure sensors and microphones built into the skin of the UAV for the test cases with and without a rotating propeller. A significant effect of the propeller on the level of pulsations was found. An increase of the incoming flow velocity led to a weakening of this effect. Analysis of the spectral data of the disturbances did not reveal a direct relationship between the propeller noise and the unsteady characteristics of the separation zone.
带螺旋桨无人飞行器上压力传感器的分流检测问题
摘要 对装有推动式双叶螺旋桨的小型无人驾驶飞机的气流分离区的脉动特性进行了实验研究。在风洞中，通过内置在无人机蒙皮上的非稳态压力传感器和麦克风，对有螺旋桨和无螺旋桨的试验情况进行了测量。结果发现，螺旋桨对脉动水平有明显影响。入流流速的增加导致这种影响减弱。对干扰频谱数据的分析并未发现螺旋桨噪声与分离区不稳定特性之间的直接关系。

期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
