Aircraft system with stretching function

Abstract

The invention discloses an aircraft system with a stretching function. The aircraft system comprises an aircraft body, propellers and telescopic wings, and at least two propellers are arranged on theaircraft body and symmetrically arranged on the two sides of the aircraft body; each propeller is connected with a speed reducer through an angle adjusting rotary shaft, the speed reducers are arranged in the positions, corresponding to the propellers, in the aircraft body and are in transmission connection with motors, the angle adjusting rotary shafts are driven by the motors through the speed reducers to rotate, and therefore the propelling angles of the propellers are adjusted; and universal joints are arranged on the middle portions of the angle adjusting rotary shafts, the front ends ofthe angle adjusting rotary shafts are sleeved with rotary shaft sleeves, propeller telescopic cylinders are arranged in the positions, corresponding to the horizontal sides of the angle adjusting rotary shafts, on the aircraft body, propeller telescopic arms of the propeller telescopic cylinders are connected with the rotary shaft sleeves, the propellers are driven by the propeller telescopic armsof the propeller telescopic cylinders to rotate left and right around the universal joints, and therefore the expanding angles of the propellers are adjusted. Each of the two sides of the aircraft body is provided with one telescopic wing, and at least two wing telescopic cylinders are arranged in each telescopic wing.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an aircraft system with a stretching function. Background technique [0002] At present, the common multi-rotor (propeller) vertical take-off and landing drones or helicopters are almost all concentrated in the consumer field, and multi-rotor vertical take-off and landing drones are professionally classified as consumer-grade drones. Its payload is only a few hundred grams to a few kilograms. Due to the limitation of the industrial chain and its own technical conditions, a large number of UAV R&D companies in China have not yet developed a multi-rotor UAV with a large payload. Their products are more used. It is used for aerial photography, entertainment or to complete a very small amount of industrial flight missions. [0003] The advantages of traditional fixed-wing aircraft are fast flight speed, long range and cruising time, but the disadvantages are long take-off and landi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a kind of aircraft system with stretching function, solve the problem of the occupation of the aircraft due to the long wings of the fixed-wing unmanned aerial vehicles and the suspension of multi-rotors (propellers) on the fuselage. The space is relatively large, which increases the occupied space of the aircraft, which is not conducive to the long-term development of fixed-wing UAVs

[0006] It also solves the problem that the propellers of the existing multi-propeller aircraft adopt fixed installation and cannot realize multi-angle power propulsion
