CUSTOMER-REFURBISHABLE, NON-PYROTECHNIC, SCALABLE HDRM TECHNOLOGIES
Hold down release mechanismsare used to secure and deploy satellites and satellite appendages including solar arrays, reflector antenna, booms, and masts. Historically, release devices of this type have included explosive release nuts, bolt cutters, separation nuts, as well as wire and pyro cable cutters. Glenair non-explosive HDRMs employ a fusible wire-actuated nut technology that solves many of the problems associated with explosive hold down and release devices, including easy on-site refurbishment after test. Certain designs are now manufactured by Glenair Space Systems in Salem, Germany. Glenair US-manufactured non-pyrotechnic and customer- refurbishable medium-duty HDRMs and pin pullers can ship to most customers worldwide without an export license, although light- and heavy-duty HDRMs do typically require one.
