Buffer device for airship

Abstract

A buffering device for an airship comprises a buffering air cushion and an inflation device, wherein the buffering air cushion comprises an inflatable framework structure and an outer bag arranged outside the framework structure in a sleeving mode, an inflation opening connected with the inflation device is formed in the framework structure, and an exhaust hole and a connecting piece used for being connected with the airship are arranged on the outer bag. According to momentum and energy conservation, when the airship lands, the formed outer bag is compressed to exhaust air from the exhaust holes, the exhausted air has enough speed to carry certain energy, impact energy of the airship on the ground is absorbed, and therefore buffer protection of the airship is achieved.

Description

technical field [0001] The invention is used in the field of aerostats, in particular to a buffer device for airships. Background technique [0002] As a lighter-than-air aircraft, airships can be used in many fields such as transportation, transportation, disaster relief, and scientific experiments. Airships usually need to carry a variety of power, energy, and mission equipment. These devices are generally installed on the airship pod at the bottom of the airship. When the airship lands, the pod first contacts the ground. Since the airship lands with a certain landing speed , Many uncontrollable factors such as excessive speed or sudden environment during the descent often lead to excessive impact overload when the pod falls to the ground, resulting in damage and loss to the power supply equipment or task equipment. [0003] Chinese utility model patent CN201120420972 discloses an airship cushioning device that can replace the landing gear, and adopts the air extrusion fl...

AI Technical Summary

Problems solved by technology

However, this structure will cause secondary damage to the need for cushioning equipment to form a rebound. At the same time, a large amount of air source is required to inflate and maintain the pressure of the capsule body, resulting in troublesome air source storage and slow inflation molding time, which affects the usability of the product.
