Abstract
The main functions of the space instrument structural subsystem are to enclose, protect and support the other instrument subsystems integrity and to provide a mechanical interface with the spacecraft. Depending on the mission requirements and the mechanical load envelope defined by the spacecraft, the structure should sustain the severe stresses and loads experienced during the launch. The main challenge for a successful structural design is to consider an appropriate verification method during the design phase, which discards or minimizes the potential hardware failures during the qualification tests. This is not always trivial because the design inputs and requirements at the preliminary design phase (phase B) may change when reaching to the stage that the instrument is built and needs to be qualified by test (phase D). In this paper, based on the lessons learned in the scope of the Electron Proton Telescope and High Energy Telescope (EPT-HET) instrument development for ESA?s Solar Orbiter mission, a systematic approach for a successful structural design is presented. The proposed approach not only includes the structural stress and strength analysis but also involves the fatigue life and shock damage verification for sensitive parts such as electronic components.
