Types of Aircraft Cables
1. Stainless Steel Aircraft Cables
Stainless steel cables are highly resistant to corrosion, making them ideal for harsh environments. They are typically used in critical applications such as flight controls and landing gear systems. These cables are known for their high tensile strength, which can range from 120 pounds to as much as 14,400 pounds, depending on their construction. Companies like Loos & Co., Inc. and Aircraft Spruce offer a variety of stainless steel cables suitable for mission-critical applications.
2. Galvanized Steel Aircraft Cables
Galvanized cables are coated with a protective layer of zinc, providing some degree of corrosion resistance. While not suitable for flight control systems, they are often utilized in general-purpose applications such as slings and winch lines. These cables typically offer a lower tensile strength compared to stainless steel options. Manufacturers like US Netting provide galvanized steel cables that meet various commercial standards.
3. Mil-Spec Aircraft Cables
Mil-spec cables adhere to military specifications, ensuring they meet stringent performance criteria. These cables are crafted from high-strength materials designed for aerospace applications. They are often used in flight control systems and other critical environments where safety is paramount. Companies like Bergen Cable Technology specialize in manufacturing these high-quality cables.
4. Control Cables
Control cables are essential for the operation of various aircraft systems. They often come in specific sizes, such as 3/32 and 7×19 configurations, to suit different applications. These cables can be made from either stainless steel or galvanized materials, depending on the operational requirements. Aircraft Spruce offers a range of control cables tailored for various needs.
5. Cable Assemblies
Cable assemblies combine multiple cables into a single unit, simplifying installation and enhancing functionality. These assemblies can be customized to meet specific operational requirements, offering a versatile solution for aircraft systems. Companies like GIGAFLIGHT focus on providing high-quality cable assemblies designed for aerospace and defense applications.
Applications of Aircraft Cables
Flight Control Systems
Aircraft cables are crucial for operating flight control systems. They connect various control surfaces like ailerons, elevators, and rudders, allowing pilots to maneuver the aircraft effectively. The reliability and performance of these cables are paramount, as they directly influence flight safety.
Landing Gear
Landing gear systems rely on aircraft cables for deployment and retraction. These cables must withstand significant stress and strain, making high-tensile strength materials essential. Manufacturers like McFarlane Aviation offer cables specifically designed for landing gear applications.
Emergency Systems
In emergencies, aircraft cables play a vital role in deploying safety systems. These cables must be reliable and capable of performing under pressure, ensuring that critical systems function as intended. The use of mil-spec cables in such applications is common due to their robust performance.
General Purpose
Apart from critical applications, aircraft cables are also used in general-purpose scenarios. This includes applications like slings and winch lines, where galvanized cables are often adequate. Companies like US Netting provide these cables for various non-critical uses.
