Aircraft Cable Assemblies – Types And Applications
Aircraft cables, also referred to as wire ropes, are essential parts used in the aerospace sector for control systems, suspension, and structural applications, among other uses. Depending on their intended use, the three main types of aviation cables are non-metallic, galvanized, and stainless steel. Each has unique benefits and drawbacks. This thorough reference examines the traits, advantages, and disadvantages of these three kinds of aviation cables as well as their particular applications in the aerospace industry.
Stainless Steel Aircraft Cables
Characteristics
High-strength stainless steel alloys, usually 302, 304, or 316 grades, are used to make stainless steel cables. Because of the severe environmental conditions seen in aviation, these alloys offer exceptional corrosion resistance. Moreover, stainless steel cables are a good choice for demanding applications owing to their strength and longevity.
Benefits
Corrosion resistance: Stainless steel resists corrosion well, which makes it perfect for usage in damp and temperature-variable situations.
High strength: Stainless steel can bear heavy loads and strains because to its high tensile strength.
Durability: The extended service life of stainless steel cables lowers the need for frequent maintenance and replacements.
Drawbacks
Cost: Compared to other materials, such as galvanized steel, stainless steel is more expensive.
Weight: Since stainless steel cables are typically heavier, this may have an effect on the aircraft’s total weight.
Applications
Control systems: Stainless steel cables are frequently employed in flight control systems, such as ailerons, elevators, and rudders, where accurate and dependable control is critical.
Bracing and structural support: Stainless steel cables are utilized in bracing applications in order to preserve the integrity of the aircraft’s structure and offer structural support.
Safety harnesses: Stainless steel cables are frequently utilized in safety harnesses and restraints for both crew and passengers given their strength and longevity.
Galvanized Aircraft Cables
Characteristics
In order to prevent corrosion, carbon steel is coated with a layer of zinc for making aircraft cables. This kind of cable is a flexible option for a range of applications as it provides a good mix between strength and rust resistance.
Benefits
Cost-effective: Galvanized cables are a cost-effective solution for many applications since they are often less expensive than stainless steel cables.
Good corrosion resistance: The zinc coating offers sufficient protection against rust and corrosion, making it perfect for damp situations.
Strength: High tensile strength galvanized cables make them ideal for a range of structural and control applications.
Drawbacks
Reduction in corrosion resistance: Over time, the zinc coating may wear off, making the cable less resistant to corrosion.
Maintenance: Compared to stainless steel cables, galvanized cables may need more regular inspections and upkeep.
Applications
Landing gear: Because galvanized cables can withstand significant weights and are resistant to corrosion, they are frequently utilized in landing gear systems.
Control surfaces: Because these cables are less resistant to corrosion than stainless steel, they are often utilized in control surface applications.
Non-critical support structures: In situations where a high level of strength is needed but there is less chance of serious corrosion, galvanized cables are the ideal choice.
Non-Metallic Aircraft Cables
Characteristics
The most common materials used to make non-metallic aircraft cables are synthetic polymers with exceptional strength, such as Dyneema, Vectran, or Kevlar. These materials have special qualities including high strength-to-weight ratios and moisture and chemical resistance.
Benefits
Lightweight: Compared to metallic cables, non-metallic cables are substantially lighter, which can contribute to overall weight reduction in the aircraft.
High strength-to-weight ratio: These cables are appropriate for high-performance applications because of their remarkable strength in relation to their weight.
Chemical resistance: Non-metallic cables offer long-term dependability in a variety of settings, thanks to their resistance to a wide range of chemicals, oils, and moisture.
Drawbacks
UV sensitivity: Over time, exposure to UV light can cause some synthetic materials to deteriorate.
Cost: The cost of high-performance synthetic materials may go up in relation to the total cost of the aircraft’s components.
Temperature sensitivity: The performance and endurance of non-metallic cables may be impacted by severe temperature conditions.
Applications
Electrical and fibre optic systems: Because non-metallic cables are non-conductive, they are frequently utilized in electrical and fibre optic systems.
Lightweight support structures: These cables are perfect for lightweight support structures where reducing weight is crucial.
Emergency systems: Due to their lightweight design and dependability, non-metallic wires are utilized in emergency systems like parachute deployment mechanisms.
