Problems solved by technology
This method can ensure the simplicity of the structure, but the energy is converted from chemical energy to electrical energy, and the efficiency loss is relatively large.
[0005] Known patent No. is CN 204210733 U "a kind of hybrid quadrotor aircraft", adopts fuel engine to provide the main lift of flight, and electric motor is used as auxiliary power to provide attitude adjustment lift. In this invention, there is no mention of overcoming the impact of fuel engine on the aircraft. The anti-twist problem caused by the aircraft, so it is difficult to fly a multi-axis aircraft without a design to overcome the anti-twist method

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Depend on Figure 1-3 It can be seen from the illustrated embodiment that this embodiment includes a disc-shaped equipment installation platform 1, on which a fuel engine 2 is fixed, and the fuel engine 2 adopts a gasoline engine (model: ZENEP20 or OS 38200 GT-22). The rotating output shaft of the engine is provided with a flight rotor 3 for generating lift, and four attitude adjustment rotor installation arms 4 are arranged radially around the equipment installation platform 1. The four attitude adjustment rotor installation arms 4 have the same structure and are all bent upwards. The arc shape of the four attitude adjustment rotors 9 is slightly higher than the flight rotor 3; the end of the attitude adjustment rotor installation arm 4 is fixed and controlled by the anti-twist adjustment of the aircraft attitude control syste...

The invention discloses a hybrid long-endurance multi-axis aircraft, which comprises an equipment installation platform, on which a fuel engine is fixed, on the rotary output shaft of the fuel engine is provided with a flight rotor for generating lift, on the equipment installation platform A plurality of attitude adjustment rotor mounting arms are arranged radially around, at the end of the attitude adjustment rotor mounting arm is fixed the anti-twist adjustment steering gear controlled by the aircraft attitude control system, on the angle adjustment motor fixing bracket of the anti-twist adjustment steering gear To fix the DC motor, an attitude adjustment rotor is provided on the rotary output shaft of the DC motor; an aircraft support tripod is provided below the equipment installation platform. It has the characteristics of reasonable structure, light weight and long battery life.
Description
technical field [0001] The invention relates to a hybrid long-endurance multi-axis aircraft. Background technique [0002] At present, most multi-axis aircraft use lithium polymer batteries as the power source. Because their energy density is much lower than that of biofuels, the battery life is basically within 30 minutes, and the batteries are heavy, which limits the load of the aircraft. And in actual use, the discharge current of the purely electric multi-axis aircraft is large, resulting in a limited number of charging cycles for the lithium polymer battery, resulting in dozens of lags that must be replaced, resulting in high usage costs. [0003] Purely fuel-powered multicopters are also theoretically possible, and some related researches are in progress, but this type of aircraft will lose the biggest advantage of existing multicopters, that is, simple structure. Its complex variable collective pitch structure will make the payload, reliability, size, and cost uncont...
