High-Reliability, Non-Explosive (Split-Spool) Separation Nuts and Electromechanical Release Mechanisms for Dependable Stowage and Release of Deployable Space Systems
Hold Down and Release Mechanisms are electromechanical devices used in the deployment of satellites and other payloads in space. Supplied in various formats and measured-release preloads, the devices are optimized for foolproof release-reliability with built-in mechanical and electrical redundancy. In non-pyrotechnic HDRMs, the planned release of the deployable satellite/payload is activated by a pre-determined value of electrical current to a fuse-wire system which causes the wire to break under tension and allows a pre-loaded mechanical bolt to actuate.
Glenair's line of low-shock, redundant and non-redundant space mechanisms includes both HDRM devices as well as a family of pin pushers and pin pullers. Customer-defined housing and mounting configurations are available. Consult factory for specific device TR level and qualification test reports.
