An airship multi-rotor compound aircraft

Abstract

The invention discloses an airship multi-rotor composite aircraft, which belongs to the technical field of aircraft design. Specifically, it is a composite aircraft that combines an airship with a multi-rotor aircraft, including a fuselage, arms, motors, propellers, fuselage cover doors, rear auxiliary rods, front auxiliary rods, airbags, snorkels, air pumps and helium gas. Bottle, when the composite aircraft is flying at high speed, the airbag is folded and shrunk inside the fuselage; after entering the hovering state, the airbag is released from the inside of the fuselage, and gradually inflated to generate buoyancy, making the composite aircraft hover in the air. The motor of the compound aircraft stops running, prolonging the endurance time of the compound aircraft. The airship multi-rotor composite aircraft proposed by the present invention solves the problem of the slow flight speed of the airship and the short battery life of the multi-rotor aircraft. At the same time, the helium used in the composite aircraft can be recycled, so that the use cost of the composite aircraft can be improved. effective control.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, in particular to an airship multi-rotor composite aircraft. Background technique [0002] Unmanned aerial vehicles have already played an important role in border patrols, earthquake relief, line inspection and other fields. Since most of these areas that require the use of drones do not have runways for taxiing, takeoff and landing, people often use multi-rotor aircraft that can take off and land vertically. However, although the multi-rotor aircraft can take off and land vertically on the spot, the way it stays in the air is to use the rotors to continuously rotate to generate lift against gravity. Most lower multi-rotor aircraft can only stay in the air for a short time. This is inconvenient for most observation and photography tasks. [0003] In addition to multi-rotor aircraft, inflatable airships can also achieve vertical take-off and landing on the spot, and the lift generation ...

AI Technical Summary

Problems solved by technology

The disadvantages of the airship are also obvious, that is, its own horizontal movement ability is poor, the wind resistance ability is poor, it is difficult to achieve large-scale rapid movement, and it cannot be competent for observation tasks that need to quickly reach the observation location

Zhengzhou Aeronautical Industry Management College Wang Xiaolu et al.’s patent application number CN201610478903 proposes a boat-wing multi-rotor UAV, which combines the multi-rotor aircraft with a fixed inflatable airship to enhance the endurance and load of the UAV. However, this airship The fixed design of the boat bag greatly increases the resistance of the aircraft during forward flight, and the flight speed of the aircraft will be at a very low level, which is not conducive to quickly reaching the target sky
