Airship multi-rotor composite aircraft

Abstract

The invention discloses an airship multi-rotor composite aircraft and belongs to the technical field of aircraft design. A composite aircraft in combination with the airship and a multi-rotor aircraftspecifically comprises a fuselage, aircraft arms, a motor, a propeller, a fuselage cover door, a rear auxiliary rod, a front auxiliary rod, an airbag, a breather pipe, an air pump and a helium gas bottle. When the composite aircraft flies at high speed, the airbag is folded and contracted inside the fuselage; after the composite aircraft enters a hovering state, the airbag is released from the inside of the fuselage and is gradually inflated and expanded to generate buoyancy, so that the composite aircraft hovers in the air, the motor of the composite aircraft stops running at this time, thereby prolonging the flight duration of the composite aircraft. With the airship multi-rotor composite aircraft provided by the invention, the problems that the flight speed of the airship is slow and the flight duration of the multi-rotor aircraft is short are solved, and meanwhile the helium gas used in the composite aircraft can be recycled so that the use cost of the composite aircraft can be effectively controlled.

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 ...

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
