Helicopter course tail locking test device and method

Abstract

The invention belongs to the technical field of aviation, and discloses a helicopter course tail locking test device and method. The device comprises a pedestal, a positioning shaft, a first deep groove ball bearing, a rotating disc, and limiting pieces; a helicopter is fixed on the rotating disc; the base is fixed to the ground; a drill hole is formed in the center of the base; the first deep groove ball bearing is embedded into the drill hole; the positioning shaft is installed in the deep groove ball bearing; at least one circle of round holes is formed in the upper surface of the base around the circle center; a universal ball bearing is embedded into each round hole; the rotating disc is coaxially installed above the base; the lower surface of the rotating disc makes contact with theupper surfaces of the multiple universal ball bearings on the base; the limiting pieces are fixed to the upper surface of the base; the upper extending parts of the limiting pieces are located above the rotating disc; and gaps are reserved between the extending parts of the limiting pieces and the rotating disc. The device is simple in structure and can be applied to all helicopters/unmanned helicopters; and the size of the device can be matched with the size of the helicopters/unmanned helicopters.

Description

technical field [0001] The invention belongs to the technical field of aviation, and in particular relates to a helicopter heading tail lock test device and a method thereof. Background technique [0002] In the development of existing helicopters / unmanned helicopters, the matching of main rotor pitch and tail rotor pitch (dual-rotor helicopter / dual-rotor pitch differential of unmanned helicopter) is generally achieved through design, calculation, analysis, simulation, simulators, and special test equipment. and three-axis turntable etc. to achieve. [0003] For the helicopters / unmanned helicopters developed by the people that have emerged in recent years, on the one hand, the design, calculation and analysis capabilities are insufficient, and on the other hand, simulation, simulators, special equipment, and three-axis turntables are expensive. For helicopters / unmanned helicopters to take off There is no good solution to the previous problem of matching the main propeller p...

Problems solved by technology

[0003]For the helicopters / unmanned aerial vehicles developed by civilians that have emerged in recent years, on the one hand, the design, calculation and analysis capabilities are not enough; on the other hand, simulation, simulators, special equipment And the three-axis turntable is expensive. There is no good solution to the matching problem of the main propeller pitch and the tail propeller pitch before the helicopter / unmanned helicopter takes off. In many cases, the main propeller pitch and the tail propeller are adjusted through test flights. distance matching relationship, this method has a greater security risk
