Mechanical Design
The mechanical design is based on the design of the VibraDamp experiment.
Some aluminium parts will be replaced by CFC-components to reduce mass.
During PDR the team agreed to use a 300mm RX-Standard module to save
approximately 0.9 kg on the structure additionally.
The chosen material for the carbon fibre reinforced parts will be a MD55
carbon fibre laminate with an anodized and vented aluminium honeycomb.
This material is space environment tested and certificated and will be
processed in a qualified workshop.

Table 5: Carbon fibre materials
All mountings and threads in the laminate will be reinforced by AL-Inlets with
HeliCoils to avoid deformations of the honeycomb. The sponsoring company
ADCO is going to support the planning by consulting the structure responsible
team members.
The principle of the locking mechanism as well as the mounting on the outer
structure will not be changed because it is tested and worked properly on
RX7.
