*** Actually, I don't think this is true --> *** For Raziel's rover deployment, a sabot assembly was initially developed, but ultimately did not make it into flight hardware. Included here are lessons learned during the making of the sabot.
Components
A sabot is used to enclose a payload for launch, and - in Raziel - consists of two main sub-assemblies: the foam sabot shell and the inner metal enclosure.
Sabot shell halves in closed configuration. Rover enclosure in open configuration.
The square enclosure fits into the sabot shell to create a housing, further modifiable to be robust enough to withstand a rough landing.
The flight competition required the enclosure to be shaped to resemble a Cube-Sat designation 2U.
Deployment Mechanism
Torsion spring hinges were installed along the pivoting edge of the enclosure connecting its two halves, allowing the energy in the springs to be stored while the sabot is in closed configuration. To remain in closed configuration, the sabot was held together by one loop of (dimension) rope, tied around.
Deployment is achieved when a team-built PRC (Pyrotechnic Rope Cutter) installed by the loop of rope activates and cuts the rope, releasing the torsion sprin
Materials and Preparation
Stiff foam was used to fabricate the sabot shell in the aim of absorbing impact upon landing.
