Abstract

Negative pressure variant airship and control method based on temperature-controlled deformation of shape memory alloy, including airbag, keel skeleton, pod, flexible solar cell and flexible electric heater; the keel skeleton is arranged inside the airbag to support the airbag; the keel skeleton The materials are all shape memory alloy materials; flexible solar cells are coated on the outer surface of the airbag; flexible electric heaters are used to heat the keel frame; The flexible electric heater is connected. The invention adopts the shape memory alloy material as the keel skeleton of the airship, effectively utilizes the one-way or two-way memory characteristics of the shape memory alloy in the temperature-changing state, and realizes the variation of the airship by controlling the temperature of the keel skeleton, and then realizes the lifting of the airship. Empty, attitude adjustment and recovery, etc. During the airship variant process, solar energy is effectively used as a functional device, thereby greatly reducing the weight of the airship.

Description

technical field [0001] The invention relates to the field of aerostats, in particular to a negative pressure variant airship based on temperature-controlled deformation of a shape memory alloy and a control method. Background technique [0002] An airship is a kind of aerostat, which is an aircraft that uses a gas lighter than air to provide lift. It generally consists of a streamlined hull, a pod carrying a load, an empennage for stability control, and a propulsion device. Generally, from a structural point of view, airships can be divided into three types: rigid airships, semi-rigid airships and soft airships. [0003] The idea of ​​negative pressure or vacuum airship was proposed as early as the 1770s. Charles P Burgess of the United States proposed in 1927 that based on the development level of material science at that time, it was impossible to design and manufacture vacuum balloons or vacuum airships. There is a pressure difference between the inside and outside of th...
