The layout of the frame, which will be built from Aluminum 6061 series, will be designed in a way capable of supporting all technical requirements, for example the installation of the internal equipment. The design shall also tackle important constrains, mainly the restricted space availability, but also the center of gravity and the torque inertia. During launch the CubeSat will be subjected to large G forces (up to 18 G, depending on the launcher), vibrations and acoustic noise. Therefore, it is imperative to perform dynamic and static analyses. The basic characteristics of our Cubesat are:
1. Dimensions: 100 mm x 100 mm x 340,5 mm
2. 3U (units)
3. Total weight of the Cubesat:4 kg (mass budget pending)
The purpose of the vessel is to protect and encase our mission’s experiment. The vessel is pressurized, containing atmospheric air with a pressure of 1 atm. One very important issue that need to be solved is the placement of all parts of the experiment inside the vessel. These parts are:
1. The microfluidic chip on which the experiment will be conducted.
2. The microscope which will be recording our results.
3. The growth medium and waste containers.
Our subsystem is going to provide the solution for keeping the microfluidic chip in focus and aligned with the microscope, enabling the collection of high-quality images. Finally, it is very important that the vessel be kept airtight, which is going to be achieved by the use of O-rings. Pressure release valves shall also be in place on the vessel to avoid explosive situations.
