Structure
Objectives
* To withstand the forces acting during launch and ejection
* To protect the satellite electronics from thermal issues
* To accommodate and protect the sub-systems during the entire mission.
* To design a structure this is compatible with all the ejection systems.
* To maintain CUBESAT standards.
Material: High grade Aluminum Alloy which is space qualified.
Specifications
* The CubeSat shall be 100.0+0.1 mm wide (X and Y) and 113.5+0.1 mm tall (Z).* Rails are smooth and edges must be rounded to a minimum radius of 1 mm.
* No external components other then the rails shall be in contact with the internals of the Ejection system.
* Each rail shall be a minimum of 8.5 mm wide.
* At least 75% of the rail must be in contact with the Ejection system rails. 25% of the rails may be recessed and NO part of the rails may exceed the specification.
* All rails must be anodized to prevent cold-welding, reduce wear, and provide electrical isolation between the CubeSats and the Ejection system.
* Separation springs must be included at designated contact points.
Stages of development
* Initial design of the structure incorporating all the subsystems of the satellite.* Meshing of the design.
* Analysis of the design.
* Prototype fabrication.
* Qualification and Acceptance tests.
* Flight model fabrication.
