Abstract

The invention relates to a window body device and a military helicopter with the same. The window body device comprises a base, a transparent piece, a sliding rail part and a limiting piece, wherein the sliding rail part comprises a first sliding rail and a second sliding rail which are parallel to each other, the limiting piece is connected with the first sliding rail and the second sliding rail,and the transparent piece is slidably mounted on the first sliding rail and the second sliding rail; and the sliding rail part and the limiting piece are bonded on the base through an adhesive, and the adhesive comprises polyurethane structural glue and a primer coating treatment agent. The problem that sliding rail falling, sliding rail cracking, sliding rail glue failure, rain leakage and the like frequently occur on a window body is solved through the cooperation of the polyurethane structural glue and the primer coating treatment agent.

Description

technical field [0001] The invention relates to the field of windows, in particular to a window device and a military helicopter containing the same. Background technique [0002] The movable windows widely used in the fields of airplanes and ships are generally used to meet the requirements of lighting, ventilation, maintenance, etc. By pushing the movable windows, the windows can be opened or closed to achieve the purpose of use. [0003] The slide rails of the existing movable windows are generally connected to the substrate by screws, glue bonding or screw+glue bonding. The speed of civilian helicopters is low, and the vibration is much milder than that of military aircraft. They are generally fixed by screws + sealant to meet the requirements of use. However, military helicopters are fast in flight, and they need to conduct various training and fire shells, so the glass is subjected to greater force, vibration, and environmental changes in high temperature and low temp...
