Problems solved by technology

[0004] At present, in the design of the domestic helicopter wind tunnel test device, the motor and the reducer are installed and connected on the test bench as a fixed device, and do not follow the transmission system, which leads to the connection transmission form between the reducer output shaft and the transmission shaft The design is complicated, the processing is difficult, the maintenance is difficult, the cost is high, and the conventional helicopter test device adopts a single fulcrum support to realize the change of the attitude angle of the test model, which has obvious device tilt characteristics, and it is difficult to ensure the balance of the center of gravity of the device

Abstract

The invention discloses a transmission, tilting and vibration reduction system of an icing wind tunnel helicopter test device. The transmission, tilting and vibration reduction system comprises a fixed frame, a tilting support frame which is arranged on the fixed frame, a transmission system of which the transmission shaft penetrates through the tilting support frame, a tilting shaft with one endbeing connected with the transmission system, and the other end being connected with the tilting support frame, an inclination angle driver with one end being connected with the fixed frame, and the other end being connected with the transmission system, and a shock absorber with one end being connected with the fixed frame, and the other end being connected with the transmission system, wherein the shock absorber is arranged on the other side, opposite to the inclination angle driver, of the transmission system. By adopting the transmission, tilting and vibration reduction system of the icingwind tunnel helicopter test device, the stability of the whole test device can be ensured.

Description

technical field [0001] The invention relates to a transmission, tilting and vibration reduction system of an icing wind tunnel helicopter test device, belonging to the technical field of helicopter wind tunnel tests. Background technique [0002] In the helicopter wind tunnel test, researchers often need to design a variety of different forms of helicopter rotor model wind tunnel test devices according to the focus of the wind tunnel test and the difference to be measured, so as to accurately measure the required rotor aerodynamic data. Typical helicopter wind tunnel test devices include coaxial rotor model test devices, helicopter rotor aerodynamic noise measurement test devices, etc. The above helicopter rotor model test devices are designed differently according to the size of the rotor model, the actual environment in the wind tunnel and the measurement needs. . [0003] In order to simulate the icing process of the helicopter rotor model in the icing wind tunnel, aimin...
