TOROIDAL STABILITY DEVICE (TSD)

Enhancing Stability in Helicopter Rescue Operation

The challenge

Life rafts used in rescue environments must remain stable under extreme conditions. In helicopter rescue scenarios, strong rotor downwash can:

  • Push rafts off position
  • Create unpredictable movement
  • Reduce control during extraction

Operational context

  • U.S. Coast Guard operations
  • Offshore and open-water environments
  • Helicopter rescues with rotor downwash

The switlik solution

Switlik developed the Toroidal Stability Device (TSD) as a solution to instability in rescue operations. The TSD is a full wraparound ballast system designed to stabilize the raft across its entire underside, rather than relying on isolated pockets

Key advantages

The Toroidal Stability Device (TSD) enhances overall raft performance by stabilizing the raft in demanding conditions, improving control during operations, and distributing weight evenly across
the entire structure to maintain balance and predictability

PROVEN PERFORMANCE

Our rafts are trusted by associations such as:
