Applications for Couplers in Aerospace

There are multiple applications for couplers in aerospace. Couplers are on airplanes, spacecraft and in satellites, and are used in both commercial and DOD aircraft.  Couplers serve as a mechanical linkage that transmit power and helps facilitate movement of air, liquids, and gas, in an airborne vehicle. Modern aircraft couplers have the design sophistication  to compensate for movement and misalignment, within a flexible aerostructure, assuring connection, and the uninhibited flow of air, fuel, and fluids.

Types of Aerospace Couplers

There are many different usages for aerospace/space couplers. The diversification of couplers becomes more pronounced depending on application. They come in different sizes, and shapes, determined by aircraft design and intent. Commercial requirements can be distinctly different than DOD requisites. Space vehicles usually have different design and performance criteria all-together. All that being said there is no one standard aerospace coupler.

Below is a listing and brief definition of the most common types aerospace/space couplers:

• Quick-Disconnect Couplings: These provide quick connection and disconnection of hoses, pipes, or other elements. They are used primarily in ground support equipment for fluid and electrical conveyance systems.
• Flexible Couplings: Aircraft and spacecraft in motion require couplers that compensate for misalignment and motion, which is necessary for linking rotating equipment within aircraft and spacecraft.
• Safety Couplings: They are designed to break away under overload conditions to prevent damage from over-pressurization in critical applications. Common usage is in space applications.

Aerospace

In aerospace, different types of couplers are required to meet an assortment of applications. All aerospace aircraft use some form of coupler linked to tubing for moving air, fuel, electronics and fluids within the aircraft. Avionics and electronics are employed to connect electrical and electronic components in the cockpit to other  areas throughout the aircraft. Ground Support Equipment (GSE) requires couplers that connect ground support carts to aircraft for fuelling, servicing, and other operations.

Space

Satellites may require couplers linking solar power with power distribution networks, that link to different subsystems. Many manned spacecraft  have docking and rendezvous requirements that utilize couplers for the transfer of power and motion.

Aerospace/space coupler design and manufacturing criteria:

• Reliability: Aerospace couplers operate in extreme environments. They are designed and manufactured to function reliably under extreme heat, cold and pressure.
• Durability: Couplers need to be resistant to wear and tear over an extended period of time. Robustness and resilience are a must.
• Weight Reduction/Strength: In aerospace/space aircraft, the minimizing of weight while increasing or maintaining strength is foundational. This many times requires thin-wall machining of coupler components, that optimize the weight/strength ratio.
• Safety: Safety comes first. Everything designed and manufactured is focused on safety.
• Materials: There are a diversity of raw materials used in aerospace/space couplers, depending of application. They vary from different grades of aluminium to high strength alloys. Most require precision machining of parts into complex shapes.
