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.
