Embodiment

[0016] Such as figure 1 , figure 2 and image 3 As shown, the composite multi-rotor aircraft with retractable wings, the aircraft structure adopts a full-composite material structure mainly made of carbon fiber, and combines the rotor aircraft and the fixed-wing aircraft to obtain more lift to extend the endurance time and improve load capacity. Specific structure: It mainly includes: motor 1, propeller 2, rocker arm 3, body 4, lithium battery pack 5, retractable wing 6, retractable landing gear 7 and flight control system 8. The assembly scheme of the above parts: the propeller 2 is installed on the motor 1 , the motor 1 is fixed on one end of the rocker arm 3 through a mounting piece, and the other end of the rocker arm 3 is fixed in the middle of the body 4 . The flight control system 8 is installed at the central position directly above the airframe 4; the lithium battery pack 5 is installed at the central position directly below the airframe 4; the retractable landing...

Abstract

The invention relates to a hybrid multi-rotor aircraft with retractable wings, and mainly solves the problems in the prior art that the time of endurance is short and the load capacity is limited due to causes of structure. The hybrid multi-rotor aircraft with retractable wings mainly comprises motors, propellers, rocker arms, an aircraft body, a lithium battery pack, the retractable wings, retractable undercarriages and a flight control system; the assembly scheme of all the parts lies in that the propellers are mounted on the motors; the motors are fixed at one ends of the rocker arms through installation parts, and the other ends of the rocker arms are fixed in the middle of the aircraft body; the flight control system is mounted at the central position right above the aircraft body; the lithium battery pack is mounted at the central position under the aircraft body; the retractable undercarriages are symmetrically mounted at positions, close to the two sides, below the aircraft body; the retractable wings are fixed on the retractable undercarriages through installation parts. After the aircraft takes off, the undercarriages can be retracted, and at the same time the wings stretch towards outer sides, therefore the lift force of the multi-rotor aircraft is greatly increased, the time of endurance is prolonged, and the load capacity is further improved.

Description

technical field [0001] The invention relates to a multi-rotor aircraft, in particular to a composite multi-rotor aircraft with retractable and retractable wings, belonging to the technical field of aerospace. Background technique [0002] Multi-rotor aircraft has the ability to take off and land vertically, hover in the air, and fly forward, backward, left, and right. It can achieve fixed-point landing and does not require a special airport. It can be applied to various tasks, such as deep forest fire prevention, traffic monitoring, farmland protection, aerial photography and aerial survey, etc. In recent years, with the emergence of motor technology, battery technology, and especially commercial MEMS sensors, the multi-rotor market has been detonated, especially in the field of aerial photography. [0003] Improving the endurance time and load capacity of the rotorcraft is the focus of the current rotorcraft research and development process. Generally, multi-rotor aircraft...
