Cross-rotor unmanned helicopter lift test bench

Abstract

The invention discloses a cross-rotor unmanned helicopter lift test bench, comprising an output shaft, a rotor deceleration device and an angle adjustment device for adjusting the angle between the axis of the output shaft and the horizontal direction, the angle adjustment device, the output shaft and the rotor deceleration device The devices are two, and correspond one to one, and the output shaft is installed at the output end of the rotor reduction device. The angle adjusting device includes a base and a rotating body capable of rotating around the base, the rotor reduction device is installed on the rotating body, and the base is installed on the mounting plate. An angle adjustment device for adjusting the included angle of the axis of the output shaft relative to the horizontal direction is provided. In specific use, by rotating the rotating body on the base, and then driving the rotor reduction device installed on the rotating body to rotate, since the output shaft is installed at the output end of the rotor reduction device, the rotation of the output shaft is realized, and then the output shaft is adjusted relative to the horizontal The direction included angle improves the versatility of the intersected double-rotor unmanned helicopter lift test bench provided by the application.

Description

technical field [0001] The invention relates to the technical field of test and testing mechanisms, in particular to a lift test stand for a crossed double-rotor unmanned helicopter. Background technique [0002] In the intersected dual-rotor unmanned helicopter, especially the intersected dual-rotors arranged side by side, the two rotors rotate in opposite directions. The top of the body is cross-shaped. The two rotors need to maintain a rotational phase difference at all times in order not to collide. [0003] Because there needs to be a certain angle and lateral wheelbase between the rotor shafts of the two driving rotors, the setting of the angle and lateral wheelbase will affect the lift, drag and required power of the rotors, and their settings will seriously affect the lift. performance, during the test operation, the two rotors are driven by the same power source. The position of each component in the helicopter lift test bench is fixed, so that the position of th...

[0003] Because there needs to be a certain angle and lateral wheelbase between the rotor shafts of the two driving rotors, the setting of the angle and lateral wheelbase will affect the lift, drag and required power of the rotors, and their settings will seriously affect the lift. performance, during the test operation, the two rotors are driven by the same power source. The position of each component in the helicopter lift test bench is fixed, so that the position of the output shaft fixedly connected to the rotor main shaft is fixed, so that there can only be one angle between the output shaft and the horizontal direction, that is, only one angle of inclination can be tested for the rotor, resulting in crossover Dual-rotor unmanned helicopter lift test bench has low versatility
