Airplane cockpit windshield structure with sun shading function

Abstract

The invention relates to an airplane cockpit windshield structure with a sun shading function. Based on a windshield structure of a traditional airplane cockpit, a sun shading region is determined according to a designed eye position 1 of the airplane cockpit, and in other words, a windshield region above the visual horizontal line of the designed eye position 1 of the airplane cockpit serves as the sun shading region; the outer surface of a transparent interlayer 6 adjacent to a transparent ITO conductive heating film 2 on the outer layer of a windshield is coated with a transparent second ITO conductive heating film 3; a transparent electrochromic sun shading rubber film 4 is inserted in the position between the ITO conductive heating film 2 and the ITO conductive heating film 3; and under the powering-on condition, a certain potential difference is formed between the two ITO conductive heating films, the color and light transmittance of the transparent electrochromic sun shading rubber film are changed, and therefore the shading function of the windshield of the airplane cockpit is achieved. By the adoption of the airplane cockpit windshield structure, the weight of an airplane is reduced and the economic performance of the airplane is improved; and the sun shading function is electrically controlled, the color and light transmittance of the windscreen in the sun shading region can be reversibly adjusted, and operation carried out by crew is facilitated.

Description

technical field [0001] The invention belongs to the design technology of windshield structure of aircraft cockpit. Background technique [0002] Conventional aircraft cockpit windshield adopts multi-layer inorganic tempered glass or plexiglass, PU layer, ITO conductive heating film and other materials to form a curved or flat laminated structure, and is sealed by a rubber ring to form an overall windshield, which has anti-bird impact, anti- It has functions such as ice defogging, but does not have sunshade function. In order to meet the shading needs of the crew, a mechanical shading device is often installed at an appropriate position on the upper part of the cockpit windshield. When the crew members need sunshade, they need to turn down and unfold the sunshade device to block the direct sunlight; The sunshade device may loosen and sag during long-term use, which interferes with the normal work of the crew and increases the weight of the aircraft.
