What Is the Use of Tungsten Wire in Rocket Engines?

In rocket engines, tungsten wire is usually used in the following important aspects:

Ignition system: Tungsten wire is often used in the ignition system of rocket engines. This is because tungsten wire has a very high melting point and high temperature resistance, which allows it to withstand extremely high temperatures at the moment of ignition. Rocket engine ignition systems need to ignite fuel quickly, and this property of tungsten wire makes it an ideal choice.

Combustion chambers and nozzles: Tungsten wire is also used to make combustion chambers and nozzles for rocket engines. The temperature in the rocket combustion chamber is very high, and the high melting point and high temperature resistance of tungsten wire enable it to maintain structural stability under such extreme conditions. In addition, tungsten has high thermal conductivity, which is important for effectively managing the temperature of the combustion chamber.

Jet Throat: In some rocket engines, the jet throat construction may contain tungsten filaments. These tungsten filaments can be used to help adjust the fuel and oxidizer mix within the combustion chamber for optimal performance.

Guides and rudders: Tungsten wire can also be used in rocket guides and rudders. These parts need to withstand high temperature and pressure conditions, and the high temperature resistance of tungsten wire makes it a suitable choice.
