Problems solved by technology
However, the domestic ducted tail rotor test is generally limited to the performance verification of the ducted tail rotor by the manufacturer, and there is a lack of research-type tests such as model selection and comparison in the wind tunnel.
Therefore, in order to realize the ducted tail rotor test in the wind tunnel, it is necessary to consider the wind tunnel working condition, support mode and drive form selection, and there is currently a lack of a support device for the ducted tail rotor test

The invention relates to a motor driving based test support device for a ducted tail rotor. A motor, a transmission shafting, a support mechanism and a rectification mechanism are included; and an output shaft of the motor is connected with the transmission shafting, the transmission shafting is fixedly connected with a propeller hub of the tail rotor model, one end of the support mechanism is fixedly connected with the motor through a mounting flange, the other end of the support mechanism is fixedly connected with a duct model, and the rectification mechanism is mounted outside the motor andthe support mechanism. The test device synchronously supports the duct model and a tail rotor model so that the positional relation therebetween can be accurately controlled, a transmission mechanism, driven by the motor, drives the ducted tail rotor model to rotate at a specified rotating speed, and meanwhile, a motor wire water pipe and the transmission shafting are wrapped and rectified through a fairing assembly, so that the regeneration noise in a wind tunnel test is reduced; and the test support device has the advantages of high test efficiency and repeatability.
Description
technical field [0001] The invention belongs to the field of aircraft wind tunnel tests, and in particular relates to a motor-driven ducted tail rotor test support device. Background technique [0002] In recent years, with the rise of ducted tail rotor research, the demand for ducted tail rotor aerodynamic and acoustic design test verification technology has gradually increased, and a tail rotor model is installed in the ducted model. Domestic ducted tail rotor tests are generally limited to the performance verification of the actual ducted tail rotor by the manufacturer, and there is a lack of research-type tests such as model selection and comparison in wind tunnels. Therefore, in order to realize the test of the ducted tail rotor in the wind tunnel, it is necessary to consider the working conditions of the wind tunnel, the support method and the selection of the driving form. Currently, there is a lack of a support device for the ducted tail rotor test. Contents of the...
