Synthetic things are composed of multiple parts, often with the implication that they are artificial.
In the aerospace context, synthetic refers to materials or substances that are created artificially, rather than occurring naturally. Synthetic materials are commonly used in aerospace applications due to their unique properties, such as strength, durability, and resistance to extreme temperatures and environments.
Examples of synthetic materials used in aerospace include:
-
Composites: Synthetic materials such as carbon fibers, aramid fibers, and glass fibers are used to create composite materials, which are widely used in aerospace applications due to their high strength-to-weight ratio. These composites are used in aircraft, spacecraft and even for rocket stages.
-
Polymers: Synthetic polymers, such as polyethylene, polypropylene, and polycarbonate, are used in aerospace applications for their light weight, high strength and resistance to extreme temperatures. They are used for the construction of fuel tanks, cockpit windows, and other structural components.
-
Synthetic lubricants: Synthetic lubricants such as esters and polyalphaolefins are commonly used in aerospace applications due to their stability and resistance to high temperatures and pressures. They are used in engines, gearboxes, and other mechanical systems to reduce friction and wear.
-
Synthetic fuels: Synthetic fuels such as Synthetic paraffinic kerosene (SPK) or Fischer-Tropsch diesel are used in aircraft and spacecraft to reduce emissions and increase efficiency.
Synthetic materials and substances have unique properties that make them well suited for use in aerospace applications. They are used in a wide range of applications, including propulsion systems, airframes, and control systems, and are used to improve the performance, safety, and efficiency of aerospace systems and vehicles.
