SCOPIC (Shaft Controlled Pitch Change) Technology

U.S. Pat. Pending

The future of rotor hub mechanics. SCOPIC represents a major leap forward in rotor hub mechanics, a software-defined virtual swashplate that delivers collective and/or cyclic pitch control using nothing more than driveshafts and drive motors — no swashplates, actuators, linkages, or complex mechanisms required...

  • Software defined virtual swashplate
  • No swashplates or linkages.
  • No slip rings or "fly by wire" actuators. just drive motors.
  • Cyclic and/or collective pitch control is achieved through coaxial driveshafts.
  • IBC (Individual blade control) capable, both in pitch and lead-lag.
  • For rotary-wing, fixed-wing, tiltrotor, eVTOL aircraft and watercraft. Essentially any system with spinning rotors.
  • Regenerative braking provides pitch control for autorotation and other externally driven applications like hydroelectric and wind powered generators.
  • Individual rotors may continue to operate as fixed pitch rotors in the event of a motor failure.

SCOPIC Technology

Variable/Collective Pitch Rotor System

  • Two direct drive motors drive two coaxial driveshafts.
  • Driveshafts control pitch of two or more primary rotors.
  • Corotation of motors drives rotor system.
  • Non-corotation of motors alters blade pitch.

Cyclic Pitch Rotor System

  • Two direct drive motors drive two coaxial driveshafts.
  • Driveshafts control pitch of one primary rotor which is coupled to a secondary rotor.
  • Corotation of motors drives rotor system.
  • Non-corotation of motors alters blade pitch.

Collective and Cyclic Pitch Rotor System

  • Four direct drive motors drive four coaxial driveshafts.
  • Driveshafts control pitch of two completely independent primary rotors.
  • Corotation of motors drives rotor system.
  • Non-corotation of motors alters blade pitch.
