Deployables Cubed Actuators

It is Deployables Cubed’s goal to develop actuators specifically targeting the needs of the nano satellite community. The preliminary specification of our current products, pin puller and release nut, are as follows:

  •  Designed based ECSS Standard
  • >100 actuation cycles
  • Allowable Temperature Range: -65°C to +80°C
  • Qualified product by end of 2019

  • Stroke: 6,5 mm
  • Pull Force: > 30N
  • Static Force: >100N

Release Nut:

  • Size: 16x16x14mm

The Deployables Cubed actuators enables the design of affordable deployable structures like

  • booms (e.g. for instruments with distance requirement to satellite (e.g. radar) or deployment units),
  • antennas (e.g. for communication: space to space or space to Earth) and
  • sails (e.g. for de-orbit & propulsion).

Currently, breadboard activities on these deploybles are carried out using the extensive heritage on deployable structures, especially inflatables, in the Deployables Cubed team. The first products are planned to be released soon.
