Abstract

The invention provides an aircraft inflation device, comprising an inflation nozzle (1), an inflation port cover (2), and a sealing ring (3). ) A flange structure composed of a bottom plate (12) connected to the axial end, the bottom plate (12) end of the inflation nozzle (1) is installed on the web (4) by screws, the cylinder of the inflation nozzle (1) The outer wall of the shape (11) end is equipped with an air-filling port cover (2), and a sealing ring (3) that plays a sealing role is installed between the air-filling port cover (2) and the air-filling nozzle (1), wherein the sealing ring ( 3) Place it in the groove (21) where the inflation port cover (2) fits with it. The aircraft inflation device provided by the invention is simple and convenient to install and disassemble, and meets the airtightness inspection requirements of large-volume aircraft.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and in particular relates to an aircraft inflation device. Background technique [0002] In order to make the aircraft crew and passengers have a comfortable working and resting environment, the cockpit and cabin of modern aircraft are all designed as airtight structures. After the riveting of the aircraft is completed, the sealing structure needs to be inspected for airtightness. During airtightness inspection, there must be an inflatable joint on the aircraft connected to the airtight test bench to complete the delivery of air to the interior of the aircraft. Check whether the air in the sealed structure is leaked with soapy water to determine whether the airframe structure is sealed, so as to re-test the unsealed area. Sealed to meet the airtight requirements of the body. At present, standard parts are used as inflatable devices on aircraft, but standard part inflatable devices have ...
