飞机风挡玻璃加热原理
英文回答：
The heating principle of aircraft windshield is mainly
achieved through electrical resistance heating. The
windshield is made up of multiple layers, typically two
layers of glass with a thin conductive layer in between.
This conductive layer is made of a transparent material
that has high electrical resistance, such as indium tin
oxide (ITO) or doped silicon.
When the heating system is activated, an electrical
current is passed through the conductive layer, creating
resistance and generating heat. This heat is then
transferred to the glass layers, effectively warming up the
windshield. The electrical current is supplied by the
aircraft's electrical system, typically through a dedicated
circuit.
The purpose of heating the windshield is to prevent the
accumulation of ice, snow, or frost on its surface during
flight. This is crucial for maintaining visibility and
ensuring the safety of the aircraft. The heat generated by
the windshield heating system helps to melt any ice or snow
that may have formed, allowing the pilot to have a clear
view of the surroundings.
In addition to preventing ice and snow buildup, the
heated windshield also helps to prevent fogging or
condensation on its surface. By maintaining a higher
temperature than the outside air, the windshield reduces
the temperature difference between the inside and outside,
minimizing the chances of fogging or condensation occurring.

飞机风挡玻璃加热的原理主要是通过电阻加热实现的。风挡玻
璃由多层构成，通常是两层玻璃之间夹有一层薄的导电层。这个导
电层是由高电阻的透明材料制成的，例如氧化铟锡（ITO）或掺杂硅。
当加热系统启动时，电流通过导电层，产生电阻并产生热量。
这种热量然后传递到玻璃层，有效地加热风挡玻璃。电流由飞机的
电气系统供应，通常通过专用电路提供。
加热风挡玻璃的目的是防止飞行过程中玻璃表面积冰、雪或霜
的积聚。这对于保持视野和确保飞机的安全至关重要。风挡玻璃加
热系统产生的热量有助于融化可能形成的冰或雪，使飞行员能够清
晰地看到周围环境。
除了防止冰雪积聚外，加热风挡玻璃还有助于防止其表面起雾
或产生冷凝。通过保持比外界空气温度更高的温度，风挡玻璃减小
了内外温差，从而减少起雾或产生冷凝的可能性。
