Wire Strike Protection System (WSPS®)

Magellan Aerospace designs and manufactures the Wire Strike Protection System® (WSPS®). It’s the cutting edge in helicopter safety, providing a measure of protection for helicopters in the event of accidental contact with wires with a helicopter in forward and level flight. Magellan’s Winnipeg operating division is the global expert for this system with more than 40 years of experience and 30,000+ kits delivered.

The Magellan WSPS® is designed to guides wires over the fuselage into high tensile steel cutting blades. A basic system is comprised of:

  • Upper cutter
  • Lower cutter
  • Windshield deflector

Magellan works directly with helicopter OEMs to design kits that interface with each helicopter’s unique airframe. The WSPS® uses proprietary design, analysis and manufacture of components uniquely suited to each helicopter model, and that can be optimized for each helicopter platform with mission-specific equipment. The US Army thoroughly tested WSPS® using a pendulum swing test at the NASA Impact Dynamic Test Facility in Langley. No other product has the same technical heritage as the WSPS®.

The Magellan WSPS® is:

  • Available for more than 70 models of military and commercial helicopters
  • Low cost
  • Light weight
  • Maintenance free
  • A passive system
