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

Pin Puller:

  • Size: 16x16x15mm
  • Stroke: 6,5 mm
  • Pull Force: > 30N
  • Static Force: >100N

Release Nut:

  • Size: 16x16x14mm
  • Nut: M3/M4/M5

The Deployables Cubed actuators enables next to affordable release solution (e.g. CubeSat deployers) the design of affordable CubeSat deployable structures like

  • booms (e.g. for instruments with distance requirement to satellite (e.g. radar) or deployment units),
  • antennas (e.g. for Earth Observation or Communication),
  • and others.

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