The invention is applicable to the technical field of icing wind tunnel tests, and particularly relates to a supporting device for a propeller test. The supporting device comprises a transverse supporting rod, a vertical supporting rod and a supporting base. The transverse supporting rod comprises a first cabin and a second cabin, and a driving device and a measuring device are arranged in the first cabin. The vertical supporting rod comprises a first support, a second support and a cylindrical force bearing cylinder, and the first support, the cylindrical force bearing cylinder and the secondsupport are fixedly connected in sequence. The first cabin, the second cabin and the cylindrical force bearing cylinder are sequentially, coaxially and detachably connected. According to the supporting device, a double-supporting structure is adopted, so that supporting is more stable; a supporting point is arranged at the position away from a propeller, and interference of the supporting deviceto a test is reduced; all sections of the supporting device are simple to connect and convenient to disassemble and assemble; and through the design of the shape of each section of the supporting device and a connecting structure, the interference to a test flow field is further reduced.

    本发明适用于一种结冰风洞试验技术领域,尤其是涉及一种用于螺旋桨试验的支撑装置。该支撑装置包括横支杆、竖支杆和支撑基座;所述横支杆包括第一舱和第二舱;所述第一舱内设置驱动装置和测量装置;所述竖支杆包括第一支架、第二支架和圆柱承力筒,所述的第一支架、圆柱承力筒、第二支架依次固定连接;所述第一舱、所述第二舱、所述圆柱承力筒依次同轴可拆卸地连接。本发明提供的支撑装置,采用双支撑结构使得支撑更加稳固,并且将支点设置在远离螺旋桨的位置,减少了支撑装置对试验的干扰;并且支撑装置各段连接简单,拆装方便;并且通过对支撑装置各段形状以及连接结构的设计,进一步降低了对试验流场的干扰。
