RAFTI - Rapid Attachable Fluid Transfer Interface

Satellite fill-and-drain valves combined with a simplified docking inter-face, enabling autonomous ground and on-orbit fueling.

Designed for:

  • Fill and Drain Operations.
  • On Orbit Refueling.
  • Docking and On Orbit Servicing

Features:

  • The RAFTI System integrates easily with existing spacecraft configurations.
  • Fail Safe & Safe to Fail spacecraft docking interface.
  • Three inhibits against leaks.
  • Passive retractable covers protect sealing surfaces.
  • Accommodates docking misalignment on all axes.
  • Exceeds industry safety requirements.
  • Alignment markers improve docking performance and reduce complexity of proximity operations.
