Helicopter Rotor Blades, Drive Mechanisms and Components
FSC 1615: Helicopter Rotor Blades, Drive Mechanisms and Components
Federal Supply Class (FSC) 1615 covers helicopter rotor blades, rotor head assemblies, drive mechanisms, and related rotor system hardware. These safety-critical parts are manufactured to stringent MIL-SPEC, NAS, and OEM airworthiness standards.
Rotor and drive system parts generate lift and thrust and transfer engine power to the main and tail rotors. Because a failure can be catastrophic, these items are subject to strict inspection, life limits, and traceability.
Typical items include main and tail rotor blades, rotor heads, swashplates, drive shafts, transmissions, gearboxes, and pitch links. Components are built from titanium, steel alloys, aluminum, and composites engineered for high cyclic fatigue resistance.
