Overview
Rotorcraft flight control and rotor systems experience continuous high-vibration loads that demand wiring built specifically for rotary-wing duty cycles rather than fixed-wing assumptions.
Design & Construction
High-Vibration, Fatigue-Resistant Construction
Fine-strand conductors and reinforced strain relief withstand the continuous vibration signature of rotor systems without conductor fatigue failure.
Slip Ring & Rotating Interface Wiring
Specialized wiring interfaces with rotating slip ring assemblies to carry control and sensor signals between the fixed airframe and rotating rotor hub.
Manufacturing Process
Built under AS9100D quality management with vibration and fatigue-cycle testing, supporting rotorcraft OEMs and MRO providers on flight-critical control system programs.
Typical Applications
- Rotor hub sensor wiring
- Flight control actuator cabling
- Swashplate control harnesses
- Rotor de-icing circuit wiring
- Cockpit flight control interconnects
Common installations include Rotor hub sensor wiring, Flight control actuator cabling, and Swashplate control harnesses, where flight-critical reliability and stringent weight optimization are the primary design drivers. The same base design can also be adapted for Rotor de-icing circuit wiring and Cockpit flight control interconnects with minor changes to connector type or cable length.
