Embodiment
[0016] like 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 ge...

The composite multi-rotor aircraft with retractable wings mainly solves the problems of short battery life and limited load capacity in the prior art due to structural reasons. It mainly includes: electric motor, propeller, rocker arm, airframe, lithium battery pack, retractable wing, retractable landing gear and flight control system. The assembly scheme of the above parts: the propeller is installed on the motor, the motor is fixed on one end of the rocker arm through a mounting piece, and the other end of the rocker arm is fixed in the middle of the body. The flight control system is installed at the central position directly above the body; the lithium battery pack is installed at the central position directly below the body; the retractable landing gear is symmetrically installed on both sides below the body; The wings are secured to the retractable landing gear by mountings. After the aircraft takes off, the landing gear can be retracted, and the wings are extended outwards at the same time, which greatly improves the lift of the multi-rotor aircraft, thereby effectively improving the endurance time and load capacity.
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...
