The engineer will contribute to all work packages within the CRÉSAT project, playing a central role in experimental developments. Their work will be carried out in close collaboration with a postdoctoral researcher recruited for the project at the École de l’Air et de l’Espace (EAE).

Their tasks will focus primarily on the preliminary design and development of several deployable-structure prototypes, with increasing fidelity, ranging from beam-type structures to truss-type architectures. Particular attention will be paid to replicating operational conditions, notably in microgravity environments and under shock-type loads. The dynamic characterisation of the various systems will provide input for the project’s numerical models.

The project is based on an innovative approach combining hybrid control and a wave-based representation of structural behaviour. Based on the phenomena of wave propagation, reflection and absorption, this approach notably introduces the concept of anechoic termination, which aims to limit unwanted reflections and confine vibrational energy. The hybrid control system will therefore aim to implement this type of termination experimentally. In this context, the engineer will play a key role in the experimental validation and development of the control strategy, initially passive and subsequently hybrid. In particular, he or she will be involved in the design of control laws and their real-time implementation using data acquisition systems (such as dSPACE).

Finally, particular attention will be paid to identifying and accounting for any non-linear phenomena, notably those induced by the junctions between the various structural elements.
