ATLAS GROUND 22kN
Non explosive release nut - test campaign accelerator
Key features
22 kN preload capacity
Proven axial preload performance for repeatable separation and endurance testing.
Fast, synchronizable release
Releases in under 50 ms, representative to the heritage release nuts on the market.
Representative and robust
Designed for representative behavior and repeated use throughout long development and qualification programs. Suitable as NEA substitution in demanding campaigns.
Rapid field reset
Our products are designed to be fully user operable. The initiator can be exchanged in the field, helping teams return hardware to test readiness rapidly.
ATLAS GROUND accelerates the development and qualification of release mechanisms. It preserves the proven performance of ATLAS flight hardware while extending operational life and reducing the cost per release. With fast, synchronizable release and simple field reset, teams can validate mechanisms more representatively.
ATLAS GROUND is optimized for hundreds of releases across representative test configurations. It supports a rapid turnaround between test sequences—helping engineering teams learn faster before flight.
