Problems solved by technology

The traditional electric heating aircraft windshield heating system usually adopts the current "on-off" heating control method. The system works in the form of full power and high current at the initial stage of heating, so the windshield is heated by high power and strong in a short period of time, and the temperature suddenly If the temperature rises, the glass will generate great thermal stress, which will not only reduce the life of the glass, but also cause the glass to bubble or burst when the ambient temperature is low, threatening the personal safety of the pilot.

Embodiment Construction

[0013] The technical solution will be described in further detail below in conjunction with the accompanying drawings.

[0014] Below the present invention is described in further detail, see figure 1 , an electrothermal aircraft windshield heating system. It consists of a system control panel 1, an electric heating element 2, a temperature sensor I3, a temperature sensor II4, a temperature sensor III5, a controller 6, and a windshield 7. The system control panel 1 is provided with a windshield heating switch 8.

[0015] When the windshield warming switch 8 is in the "off" position, the controller 6 does not heat and control the windshield 7.

[0016] The windshield warming switch 8 is placed in the "weak" gear from "off", the controller 6 pulls in the AC relay, and the system is in a weak heating working state. The controller judges the temperature signals of temperature sensor Ⅰ3, temperature sensor Ⅱ4, and temperature sensor Ⅲ5 respectively, and selects the temperature se...

Abstract

The invention belongs to the field of antifogging and anti-icing technology of windshields and relates to an electric heating type aircraft windshield heating system. The electric heating type aircraft windshield heating system comprises a controller and a heating windshield; a temperature sensor is arranged in the heating windshield; according to a temperature signal collected by the temperature sensor, the controller judges whether the signal satisfies a set threshold or not; if the signal satisfies the set threshold, the heating windshield is pre-heated first; after the heating windshield reaches a preset heating set temperature, the heating windshield is normally heated. According to the electric heating type aircraft windshield heating system, on the basis of reasonably controlling the glass heating speed, the external surface of an aircraft windshield can be effectively prevented from icing up and the water mist on the internal surface of the aircraft windshield can be rapidly removed; therefore, the piloting safety of a pilot is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of windshield anti-fog and anti-icing, and relates to an electric heating type aircraft windshield heating system. Background technique [0002] The icing and fogging on the windshield of the aircraft directly affects flight safety. The traditional electric heating aircraft windshield heating system usually adopts the current "on-off" heating control method. The system works at full power and high current at the initial stage of heating, so the windshield is heated by high power and strong in a short time, and the temperature suddenly If the temperature rises, the glass will generate great thermal stress, which will not only reduce the life of the glass, but also cause the glass to bubble or burst when the ambient temperature is low, threatening the personal safety of the pilot. Contents of the invention [0003] The technical problem solved by the present invention is to provide an electrothermal aircraf...
