Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of unmanned plane, concretely relates to a load self -adaptation suspension unmanned plane. BACKGROUND

[0002] The traditional multi-rotor unmanned plane needs to provide thrust in the vertical direction through the rotor when hovering in the air. This not only consumes a lot of energy during flight, but also continuously consumes energy even when hovering. Although light density materials are used during production and manufacturing, the unmanned plane still has a certain weight. Therefore, the multi-rotor unmanned plane has obvious limitations in energy consumption and weight. In addition, in order to maintain the hovering state, the propeller of the unmanned plane needs to continuously provide a large lift, which not only increases the noise, but also shortens the endurance time.

[0003] In the prior art, small unmanned airships usually adopt a traditional configuration with tail wings, and a scheme of filling a gas with a smaller density than air inside to provide lift for takeoff. In such a design, it is usually in the shape of an American football, and a tail wing is loaded at one end to control the direction of the propeller to provide power. This way has relatively long length, and the maneuverability is low by controlling the direction with the tail wing. Compared with fixed-wing aircraft, it also has high maneuverability by forward thrust, but cannot realize vertical takeoff and landing, so it needs to be assisted by a runway for takeoff, which is limited by the terrain. The traditional multi-rotor unmanned plane usually relies on its propeller to provide lift, and can realize vertical takeoff and landing. However, the horizontal maneuverability is low, because a certain inclination is needed to generate forward power, so the maneuverability is limited, and the propeller still needs to operate to provide power when hovering in the air, so the energy consumption is high.

[0004] Therefore, it is an urgent problem for those skilled in the art to provide an unmanned plane with light weight, good endurance performance, low noise, and low energy consumption. UTILITY MODEL CONTENTS

[0015] In some embodiments of the utility model, the balance air bag gas pipe is connected with four branch gas pipes, each of which is connected to one balance air bag, and a gas valve is arranged on the adaptive air bag gas pipe.

[0016] In some embodiments of the utility model, the central axis of the main air bag in the vertical direction coincides with or is parallel to the central axis of the balance air bag in the vertical direction.

Since the air bag is elastic and can change the volume, the volume can be changed according to the weight of the carried article to achieve the purpose of adaptive load.
