Abstract

The invention relates to a rotor radial locking device and method for a vertical take-off and landing aircraft. The device comprises a rotor wing motor, a miniature telescopic machine, a stop block, atelescopic rod and rotor wing blades, a fusiform rotating shaft is arranged at the bottom of the rotor wing motor, the stop block is arranged at the front end of the telescopic rod of the miniature telescopic machine, and the stop block can lock the rotating shaft in the radial direction of the rotating shaft of the rotor wing motor. The stop block is fixedly arranged at the front end of the telescopic rod of the miniature telescopic machine, and the front edge of the stop block can be completely attached to the fusiform rotating shaft of the motor. According to the radial locking device forthe rotor wing, the rotor wing rotating shaft can be locked in the radial direction of the rotor wing rotating shaft, the rotor wing is kept in the direction parallel to the longitudinal axis of an aircraft all the time, forward flying resistance of the aircraft is reduced, and 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 stop block 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 radial locking device 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 aircraft. The forwar...
