Payload / UAV Recovery

Parachute Disconnect

The FXC Parachute Disconnect protects the UAV/Payload from post-landing parachute wind drag induced damage. The FXC mechanical design works for both water and terrain landings without the need of water-sensing electronics, batteries or pyrotechnics. The design advantage is reusable and eliminates the need for a separate Water Recovery System and a separate Terrain Recovery System.

The main operational features of the FXC Parachute Disconnect are:

  • Upon the Recovery Parachute opening, tension forces are transmitted through the FXC Parachute Disconnect that is connected to the Unmanned Aerial Vehicle (UAV).
  • The line “Tension” activates the unit’s mechanical delay arming feature. This delay is necessary to prevent premature disconnect of the UAV during the initial, unstable parachute deployment sequence.
  • After the UAV system is stable under the Recovery Parachute, the Disconnect unit becomes a load-tension locking mechanism that will retain the UAV in the event of parachute oscillation. This linkage is maintained as long as the load path along the Recovery Parachute, Parachute Disconnect, and the UAV are in equilibrium.
  • Upon ground or water impact, this equilibrium is interrupted, and the resultant load reduction allows the Parachute Disconnect to separate.
  • The separated Disconnect allows the Recovery Parachute to quickly detach from the UAV.

The primary design performance advantages of the FXC Parachute Disconnect to consider in your recovery system specifications are its:

  • rugged design that makes it re-useable and cost effective
  • reliability in repeated use
  • eliminates the need for a separate Water Recovery System and a separate Terrain Recovery System for commonality and added cost savings.
