Key highlights

The Arquimea HDRM Deployment Mechanism (DEM) is a Hold-Down and Release Actuator deployment mechanism for solar arrays, antennas, thrusters, reflectors. DEM is designed mainly for the solar array deployment in small-and mid-size satellites.

Arquimea’s DEM is based on two spring motorized hinges. The DEM enables the rotation of the deployable structure from the platform. A mechanical switch is included in each hinge to ensure proper deployment of the structure.

Applications

HDRA and DEM, together or separate, can be used for:

Solar arrays
Antennas
Booms and masts
Reflectors
Cover doors
Scientific instruments
Shutter mechanisms
Large structures
Launch locks for gimbals
Thrusters
Caging mechanisms

Key features

Deployment mechanism with two spring-motorized hinges with latch on deployed position
Safety tooling to avoid deployment during AIV
Space-qualified parts and materials

Customization

Custom configurations for the complete solution are available under request. Adaptation for specific deployment angle and torque and different interfaces is possible.

Testing & qualification

EM/FM acceptance tests include:

Inspection and physical measurements (Envelop dimensions, Mass)
Electrical Measurements (Input Resistance, Grounding, Insulation)
Full Functional test at ambient temperature (deployment and detection of deployment status)

Arquimea's Quality Management System meets the requirements of UNE-EN 9100:2018 Aerospace Series and has been audited and certified by the Spanish Association for Standardization and Certification, AENOR.
