A bionic aerostat based on jellyfish

Abstract

The invention provides a aerostat based on jellyfish bionics, comprising: a helium gas bag located at the head of the aerostat for providing buoyancy; a lifting device for controlling that lifting ofthe aerostat which comprises a first air bag made of an elastic material, wherein the top of the first air bag is connected with the bottom of the helium air bag, and the bottom edge is provided withat least one first air hole and connected with the outside atmosphere; a first auxiliary wing made of shape memory alloy wires and longitudinally adhered to the outside of the first air bag; a first control device is connected with the shape memory alloy wire and is installed on the inside of the first air bag, and is used for powering on the shape memory alloy wire, shrinking the shape memory alloy wire and stretching the shape memory alloy wire when the shape memory alloy wire is powered off. The invention has simple structure, and can drive the floater to ascend by energizing the shape memory alloy wire, thereby reducing the energy consumption of ascending control, effectively sucking and exhausting air, and realizing high-efficiency ascending control.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and relates to an aerostat based on jellyfish bionics. Background technique [0002] An aerostat refers to an aircraft whose specific gravity is lighter than air and which relies on atmospheric buoyancy to lift into the air. As a safe, efficient, economical and practical flying platform, aerostats have broad application prospects in the fields of aerial photography, traffic patrol, environmental monitoring, disaster early warning, reconnaissance and surveillance. [0003] At present, for aerostats equipped with helium airbags and airbags, the lifting is achieved by controlling the mass exchange between the airbags and the outside atmosphere. However, the mass flow rate of air sucked and discharged by this method is limited, and efficient ascent cannot be achieved, and It must be equipped with valves, fans and other devices, which consumes a lot of energy and increases the structural weig...
