This paper gives details of the development and verification of a breadboard model of a pin puller for application in a hold down and release mechanism (HDRM). During the project, which is still ongoing, a compact, low weight, low shock and cost-efficient release device based on thermo-mechanical release mechanism has been developed, manufactured and tested. On top, this release device allows multiple resets with a minimum effort. Up to now the pin puller did undergo different tests and analysis in order to elaborate the maximum force and temperatures endured by the mechanism components of the device. Test conduction and results will be presented with focus on deviations from the expected behaviour and on lessons learned. The next activities are focused on the optimization of the device. Especially investigations to improve the material combination as well as component design to enhance the reliability and reduce manufacturing costs are ongoing.
