In the realm of aerospace engineering, safety and performance are non-negotiable. One critical, often unseen component that supports both is precision-engineered resistance wire designed for propeller blade anti-ice and de-icing systems.
At Pelican Wire, we manufacture a specialty resistance wire with the following characteristics:
- Alloy: Nickel-based, similar to Alloy 90
- Stranding: 8 fine strands for flexibility and uniform current distribution
- Electrical Resistance: 0.367 Ohms/ft ±1.5%
- Mechanical Profile: 3–4 turns per inch (TPI), finished nominal diameter of 0.0185
This wire is integrated into thermal boot systems, including composite sleeves installed near the hub of aircraft propellers. Depending on the system design, the wire functions either as a continuous anti-icing solution, preventing ice accumulation, or as a cyclical de-icing system, which periodically removes ice through resistive heating.
Why It Matters
Ice formation on propeller blades can lead to significant aerodynamic inefficiencies and safety hazards. This specialized resistance wire enables thermal systems to maintain optimal blade performance in sub-zero flight conditions. By maintaining clean airflow over the blades, it directly contributes to aircraft safety and mission success.
These systems are commonly used in general aviation, commercial, and military aircraft operating in cold weather environments.
