A full-scale helicopter rotor test tower

Abstract

The invention discloses a full-size helicopter rotor test tower, and belongs to the technical field of helicopter rotor test. The test tower comprises a tower, a transmission device, a force measuring device, a rainproof awning, an elevating device, a control platform and a lightning protection device; the tower comprises a tower body and a tower top platform; the transmission device comprises a motor and a transmission shaft; the force measuring device comprises a rotor balance, a rotor shaft and a rotor; the rainproof awning comprises a skeleton, a rainproof tarpaulin, a rotating shaft and a buckle; the elevating device comprises a guide rail rack, a driving motor and a driving rack; the transmission device is connected with the force measuring device via the transmission shaft and the rotor balance; the tower top platform is provided with a guardrail; the rainproof awning is fixed on the guardrail via the buckle; the guide rail rack is fixed on the tower body; the driving motor is mounted on the driving rack; and the elevating device is connected with the control platform via the driving rack. The test tower can shorten a development period, reduce risk and cost of flight test, and satisfy requirements for improvement of the rotor system and development of a novel rotor system.

Description

technical field [0001] The invention belongs to the technical field of helicopter rotor testing, in particular to a full-scale helicopter rotor testing tower. Background technique [0002] With the continuous expansion of the role of helicopters in modern warfare, it is imperative for our country to develop advanced helicopters. To achieve a series of characteristics such as good maneuverability, strong attack power, fast speed, and high survival rate, one of the most critical technical difficulties comes from Rotor system, the performance of the rotor system is directly related to the flight performance and flight quality of the helicopter. Generally speaking, the technical level of a country's rotor system represents the development level of its helicopters, and to develop its own rotor system, it must have a rotor test tower. [0003] At present, the helicopter rotor-fuselage combined model test bench, this kind of model test is of great value for the research of the app...

Problems solved by technology

[0003] At present, the helicopter rotor-fuselage combination model test bench, this kind of model test is of great value for the research of the application basis of the rotor, as well as the early rotor layout and airfoil selection research of the model, but because it can only be carried out according to the similarity criterion rotor model, it is different from the full-scale The tests are very different, and cannot replace the function of the rotor test tower, and cannot meet the development needs of the rotor system
