The students MOXA Team for the REXUS 15/16 rocket project at the University of Technology Dresden launched in May 2014. Our goal was the measurement of ozone and oxygen in the lower atmosphere.
This is our box for all the boards we need. It is easy to demount in case we have to work on the boards very fast. They regulate the power, controll heating of the sensors and handle the measured data.
It sounds simple, but it took a long time to design the PCBs (Printed Circuit Boards). After that there was a loop of testing and redesigning pass trough to come to the current design.
Our experiment module, provided by the DLR, has arrived in Dresden. We are going to re-use the bulkhead from the previous TUD Rexus team, CaRu. CaRu was launched on Rexus 11 and researched the influence of milligravity on the creation of Runge pictures, which come to live through the combined effects of capillarity and a chemical precipitate reaction.
We are currently waiting for some manufacturing parts from the TU workshop and the delivery of several commercially available parts. After all necessary elements are assembled, the vibration test will be performed under Nathanael’s management.
Due to the fact that some critical components are vertically arranged within the module, they are susceptible to vibrations during takeoff. It is necessary to ensure that these parts are not excited at their resonance frequency. We plan to measure the resonance frequency of this component, therefore we need to place several sensors at specific positions of our module.
