UAV

Kearfott UAV actuator applications include primary and secondary flight control, landing gear and utility applications. Our adaptable actuators incorporate standardized motor, controller, sensor, and gearing technologies that are industry recognized for superior performance and cost effectiveness.
 
The renowned Kearfott K-2000 actuator has been in service since its introduction over 15 years ago, and has accumulated over 1 million flight hours, many of which have been in harsh-environment service. The unique low-profile design is well suited to today’s thin wing section / volume constrained requirements.
 
Kearfott’s full line of standard high performance UAV actuator solutions are designed to be quickly adaptable, and deliver superior performance in the smallest of envelopes.
  • Low profile, compact design
  • Environmentally sealed
  • Configurable communication protocol
  • Aerospace alloy and insulation materials
  • Fits where other actuators can’t
  • Reliable operation in extreme military environments
  • Proven base design with customizable options enables short lead times to meet tight schedules
  • Powerful and lightweight

Missile

Kearfott missile control actuators and actuation systems are fielded in missile applications worldwide. They are used for thrust vector control, fin actuation, and for divert and attitude control. Kearfott custom designs its proven modules into unique packages for both discrete actuator applications and complete integrated tail kit solutions that typically include all axis and fin lock control.

  • Integrated frameless components
  • Advanced motor / motion control topology
  • Multi-use fin lock
  • Zero-backlash fin interface
  • Low friction drive disengagement
  • Multiple feedback options
  • Multiple communication protocols
  • Layered Built-in-Test (BIT) capability
  • Maximum performance in extreme thermal environments
  • Optimized weight through eliminating redundant structure
  • Re-settable / testable fin locks
  • BIT enhances mission reliability
  • High bandwidth
