It is used for the overpressure and deformation control device of the umbrella-tensioned airship airbag, which includes a parallelogram stretching mechanism on the horizontal plane, a parallelogram stretching mechanism on the vertical plane, an electric winch (3), a set of pulley assemblies and steel cables (5), and a parallelogram stretching mechanism on the horizontal plane. The stretching mechanism includes four A truss-type rods (1), and the vertical plane parallelogram stretching mechanism includes four B-truss-type rods (2). The advantages of the present invention are: during the flight of the parachute-type airship, by actively controlling the shape and volume changes of the parachute-type airbag, the influence of the change of atmospheric characteristics on the overpressure of the airbag is eliminated, and the overpressure of the airbag is controllable and basically constant, which satisfies the requirements of the parachute. Stiffness requirements of the tensioned airbag body.
Description
technical field [0001] The invention relates to the technical field of umbrella-spread airship airbags, in particular to an overpressure and deformation control device for umbrella-spread airship airbags. Background technique [0002] At present, the variant airship is a new concept airship that was proposed by the Chinese at the end of the 20th century and carried out related scientific experiments, and obtained Chinese and American invention patents in 2006. The biggest feature of the variant airship compared with the conventional airship is that the variant airship adopts an airbag structure with variable volume and shape. The overpressure of the airbag is controllable and basically constant, thereby eliminating the need for auxiliary airbags and pressure regulating devices necessary for traditional airships. When the effective load and pressure height are the same, it can effectively reduce the required airbag volume, airbag material strength requirements, and energy co...
