AEROSPACE & AVIATION
Sapphire finds numerous applications in the aerospace industry due to its outstanding mechanical, thermal, and optical properties.
OVERVIEW APPLICATIONS AEROSPACE & AVIATION
- Cockpit and sensor windows: Sapphire windows are used in aircraft and spacecraft cockpits as well as in sensors for navigation systems. Sapphire’s high transparency enables clear visibility and reliable sensor functionality.
- Structural components: Due to its exceptional hardness and strength, technical sapphire is used in structural components such as bearings, bushings, and bearing sleeves. These components must withstand the extreme conditions of space and ensure long-term durability.
- Heat-conducting components: Sapphire is also used in heat-conducting components such as heat sinks and thermal plates to improve heat dissipation in electronic systems. This is particularly important for cooling electronic components in spacecraft to ensure their proper functioning.
- Protective covers for sensors and cameras: Sapphire is used as a protective cover for sensors, cameras, and optical instruments in spacecraft. Its high hardness and scratch resistance protect sensitive components from damage by space dust and micrometeoroids.
- Communication satellites: Sapphire windows are used in high-power lasers and communication systems in communication satellites. The high optical quality of sapphire ensures reliable transmission of laser beams and electromagnetic signals in space.
