一种涡轴发动机吞冰雹装置的设计与试验

Design and Test of Hail Ingestion Device for Turboshaft Engine

重点对投射冰雹方法、冰雹速度控制、冰雹速度测量和吞冰雹装置调试等进行了研究,并利用研发的吞冰雹装置对某涡轴发动机进行了试验。得到了发动机吞冰雹试验的充足的数据图像分析资料,验证了方法的科学性、合理性。具有较好的实际应用价值和指导意义,对其它型号发动机类似试验具有一定的参考价值。

In this paper,according to the hail ingestion test requirements of the turbo-shaft engine,the hail projection method and speed control,the hail speed measurement and the overall debugging of the hail ingestion device have been mainly studied.A turbo-shaft engine has been tested by using the developed hail ingestion device.In this test,sufficient data and images have been obtained,validating that the hail ingestion method is scientific and reasonable.It has a good practical application value and guiding significance,and has certain reference value for the similar tests of other engine.
