III. Lubrication and Drag Reduction
Lubricant: Silicone lubricant has excellent high temperature resistance and chemical stability, and can provide good lubrication effect under extreme conditions. In the field of aerospace, this lubricant is widely used in the lubrication of engines and other mechanical parts to reduce wear and friction and extend the service life of mechanical parts.
Drag reduction coating: Silicone materials have low surface energy and low friction coefficient, and can be used to manufacture the outer surface coating of aircraft and rockets. This coating can reduce air resistance, increase flight speed and fuel efficiency. At the same time, silicone materials can also be used to manufacture various drag reduction components, such as fairings, flaps, etc., to further reduce air resistance.

IV. Electronics and Insulation
Electronic components: Silicone materials have high electrical insulation properties and excellent radiation resistance, and can effectively resist electromagnetic interference and radiation damage. In the field of aerospace, silicone electronic materials are widely used in the manufacture of key components such as electronic components and circuit boards to ensure the stable operation of spacecraft.
Insulating materials: Silicone insulating materials can effectively prevent the leakage of current and protect the safety of the internal electrical system of aerospace. The application of this material in the field of aerospace can significantly improve the reliability and safety of electrical systems.

V. Shock absorption and protection
Shock-absorbing parts: Silicone materials have excellent shock absorption properties and can effectively absorb and disperse impact energy. In the field of aerospace, silicone materials are used to manufacture various shock-absorbing parts, such as aircraft tires, rocket buffers, lander buffers, etc. These shock-absorbing parts can reduce impact loads and protect aerospace vehicles from damage.
Thermal protection materials: Spacecraft will be affected by high temperatures when re-entering the atmosphere, and high-performance thermal protection materials are required to protect the safety of spacecraft and astronauts. Silicone thermal protection materials have excellent high temperature resistance and thermal stability, can effectively isolate high temperatures, and protect spacecraft and astronauts from damage by thermal radiation.

In summary, the special applications of silicone in the field of aerospace cover high temperature resistance and heat insulation, sealing and leak prevention, lubrication and drag reduction, electronics and insulation, shock absorption and protection, etc. These applications not only improve the performance and reliability of aerospace vehicles, but also promote the continuous development of aerospace technology.
