Abstract [en]

This master's thesis work was performed at the department of Mechanics of the RoyalInstitute of Technology (KTH) in Stockholm as part of my Master of Science studiesin Aerospace Engineering at KTH. This thesis study has two major purposes: (1) toevaluate the performance of the spring-based ejection system used in the RAIN rocketexperiment and (2) to suggest improvements to reduce de-spin and tip-o of the ejectedprobes.To evaluate the performance of the ejection system two sets of data have been analyzed:on-ground tests data and ight data. Data from on-ground ejection tests have beenanalyzed by means of video analysis and inertial sensor analysis while for ight dataonly inertial sensor data were available. Moreover, simple mechanical analytical modelshave been created to model the behavior of the probes during the ejection.The results from data analysis and mechanical models are able to suggests some improvementsfor the ejection system. However, it is not possible to make any strongconclusion on what might have caused the de-spin and the tip-o of the probes.
