Telescopic rotor and aircraft based on rotor

Abstract

The invention discloses a telescopic rotor and an aircraft based on the rotor. The rotor comprises a rotor shaft, a chassis, a main drive motor and a drive disc which is driven by the main drive motorto rotate, wherein an arc-shaped slide slot is formed in the drive disc; a T-shaped slide slot is formed in the chassis; and the front end of the rotor shaft can be equipped with a flange which can simultaneously slide in the arc-shaped slide slot and the T-shaped slide slot without drop. On the premise of guaranteeing requirements of flight, the flange at the front end of the rotor shaft bears tangential force in the rotor shaft ring through the arc-shaped slide slot in the drive disc when the main drive motor drives the drive disc to rotate, so that power is provided for simultaneously sliding the rotor shaft in the arc-shaped slide slot and the T-shaped slide slot, and therefore, the rotor shaft linearly moves in the T-shaped slide slot, and the rotor shaft is controlled to extend andshrink relative to the drive disc. Radial extension and shrinkage of the rotor shaft can change ascending force and descending force of the aircraft, so that the aircraft can fly in a complex environment, and therefore, obstacle avoiding ability and reachable range are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a retractable rotor and an aircraft based on the rotor. Background technique [0002] With the development of society, the application of aircraft is becoming more and more extensive. It can carry a variety of loads such as cameras, fire extinguishers, etc., and can also carry measuring instrument loads for high-altitude detection or high-altitude object throwing. It is widely used in agriculture, entertainment, detection, meteorology, Rescue and other fields. [0003] The aircrafts in the prior art are rotorcrafts driven by motors for lift force, and the rotors are mostly fixed structures, so it is difficult to adjust the diameter of the rotors during flight, and they take up a lot of space when they are stored. Contents of the invention [0004] The purpose of the present invention is to provide a retractable rotor and an aircraft based on the rotor, which can e...
