Flight transparent part system and application thereof

Abstract

The invention relates to a flight transparent part system and application thereof. The flight transparent part system comprises a transparent part and a frame, the transparent part is installed on theframe, and the flight transparent part system further comprises an airflow jetting system, an air source, a temperature sensing element or thermistor and a control system, and the airflow jetting system is placed on the frame and comprises multiple spray nozzles, the spray nozzles are arranged on the exterior of a flight deck and used for jetting airflows to the transparent part; the air source is connected with the airflow jetting system and at least comprises a hot air source; the temperature sensing element or thermistor is pre-buried into the transparent part to be used for measuring thetemperature of the transparent part; the control system is connected with the temperature sensing element or thermistor to be used for monitoring the temperature of the transparent part, and is further connected with the airflow jetting system to be used for controlling the airflow jetting system to be started or shut down. According to the flight transparent part system, by jetting the airflows,deicing, defrosting and rain draining are conducted, a windshield wiper and an electric heating system of the transparent part are omitted, and therefore the flight transparent part system is more suitable for practical application.

Description

technical field [0001] The present invention relates to the field of aviation transparent parts, in particular to a flight transparent part system and its application. The flight transparent part system deices, defrosts and drains rain through airflow, and cancels the wiper and electric heating system. Background technique [0002] At present, the transparent parts of the cockpit of transport aircraft at home and abroad are composed of the main windshield, the ventilation window and the fixed window (or the combination of the ventilation window and the fixed window). In order to ensure a clear view in rainy days, the windshield is equipped with a wiper system; and to ensure all-weather flying, the windshield has an electric heating function, and the surface temperature of the windshield is automatically controlled by the controller. [0003] Wipers and electric heating systems are the basic configurations of transport aircraft windshields, and the technology is very mature. ...

AI Technical Summary

Problems solved by technology

[0005] 1) The wiper system is relatively heavy and occupies a certain weight;

[0006] 2) Fitting problem between wiper and windshield: With Boeing 787 and my country's C919 new wide-view driving

[0007] In the design of the cockpit, the radian of the windshield is complex and the area is large, so it is difficult to fit the windshield and the wiper;

[0008] 3) For general-purpose helicopters, it has high requirements on the weight of the aircraft, and the shape of the transparent parts is complicated.

[0013] 1) Energy consumption: heating film or heating wire to heat the windshield glass, each windshield needs to consume several kilowatts of electric energy;

[0014] 2) The heating material of the transparent part can be heated by a heating wire, and the heating wire has a Moire interference effect, which will affect the pilot's vision;

[0015] 3) The heating material of transparent parts can use transparent conductive film. Domestic and foreign products are mainly heated by transparent conductive film, but the heating film needs to be led out through bus bars and wires, and connected to the on-board circuit by means of a temperature control box, while bus bars and heating elements The contact part of the wire is easy to loose, and the solder joint of the wire is easy to desolder, which becomes one of the failure causes of the failure of the transparent part; and the heating film has a fault of arcing
