Abstract

The invention relates to a rotor axial locking device and method for a vertical take-off and landing aircraft. The device comprises a rotor wing motor, a miniature telescopic machine, a pressing rod,a telescopic rod and rotor wing blades, the shaft extension end of the bottom of the rotor wing motor is spiral, the pressing rod is arranged at the front end of the telescopic rod of the miniature telescopic machine, and the front edge angle of the pressing rod is consistent with the spiral angle of a spiral rotating shaft; the miniature telescopic machine is arranged on a rotor wing support, andthe front edge of the pressing rod can be completely attached to the spiral rotating shaft at the shaft extension end of the rotor wing motor. According to the rotor axial locking device, the rotor rotating shaft can be locked in the axial direction of the rotor rotating shaft, so that a rotor is always kept in the direction parallel to the longitudinal axis of the aircraft, the forward flying resistance of the aircraft is reduced, and the efficiency is improved. The device can force the static rotor wing to rotate towards a specified angle and finally lock the rotor wing at the angle. The device is simple in structure, the miniature telescopic machine and the pressing rod are convenient to install, the weight is low, and therefore the device is suitable for most vertical take-off and landing fixed-wing aircrafts.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and in particular relates to a rotor axial locking device and a locking method for a rotor-fixed-wing composite vertical take-off and landing aircraft. Background technique [0002] In recent years, the vertical take-off and landing fixed-wing aircraft combined with rotor and fixed wing has become a research hotspot because of its mature technology and the ability to obtain efficient cruise level flight, hovering in the air, and vertical take-off and landing capabilities at a relatively low cost. [0003] Vertical take-off and landing fixed-wing aircraft is a combination of multi-rotor aircraft and fixed-wing aircraft. Take-off and landing are similar to multi-rotor aircraft. The pull force provided by the multi-rotor enables the aircraft to have the ability to take off and land vertically and hover in the air; when the rotor stops working in forward flight, it is similar to a fixed-wing ...
