Summary
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
Customizations
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.
