Electrically Actuated Quick-Disconnect Coupling for Cislunar and Lunar Surface Cryogenic Propellant Transfer (ELECTRA)

Completed TRL 3 (started at 3, targeting 5)

Description

The Electrically Actuated Quick-Disconnect Coupling is a very low leakage (Dry) make/break cryogenic fluid compatible coupling that has broad application for in-space and Lunar surface refueling. This technology enables the development of vehicle on-orbit and/or on-surface cryogenic fuel transfer/refueling capability.

Project includes multiple additively manufactured components, including two independent (male and female) dual-sealing housings designed for cryogenic propellant compatibility; a coupling mate/de-mate geared rotary actuator; mated, open and close position sensors; and an optional extend/retract linear actuator system.

Benefits

The Electrically Actuated Quick-Disconnect Coupling design has a significant technical advantage over all other couplings currently being developed. When mated, it supports axial pressure loads through the coupling housings. Bayonet style couplings do not have the capability to support these axial pressure loads and tend to separate.

How to get involved

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
