Test data on material properties and material performance under cryogenic conditions are increasingly required for current and future research, development and application activities (e.g. Launcher propulsion systems). The very limited available data base does currently not cover new advanced metallic alloys, composite materials or materials manufactured with new processes e.g. Additive Manufacturing as selected and required for the next generation launcher and spacecraft missions.

The E.Inspector mission objectives are to:* Image an ESA owned space debris in its current status * Use obtained images for the verification and validation of the e.deorbit or space tug GNC sensorsFollowing a successful ESA internal CDF study, the mission is now proposed to go to phase A to be studied by industry.Several drivers make this mission design challenging:* A possible long and large (delta-V) transfer to the target* Compliance to Space Debris Mitigation guidelines from possibly high altitude* A close RDV while maintaining keep-out zones and ensuring passively safe trajectories* Tr

Cost effective opportunities for in-orbit demonstration and verification (IOD/IOV) of non-space qualified products and components should be made more easily accessible for customers. This activity is aiming at the development of a customer oriented and cost effective IOD/IOV full service based on a generic NanoSat platform.

Global optimisation methods allow finding a minimum on a global search space without restrictions, unlike finding only local extrema. A general mathematical toolbox for global optimisation is not presently available; all existing solvers and solution algorithms are narrowly specialized towards particular problem types or not available in a high-performance implementation. WORHP is a local optimiser, and hence it provides good results when it is restricted to a small search space by a user-provided initial guess.

The structures will be composed of thin-walled composite deployable booms with CFRFE (Carbon-Fibre Reinforced with Flexible Epoxy) tap-spring hinges. These tape-spring hinges will be part of the CFRP struts forming the deployable structures. The partial use of flexible epoxy resins in the CFRP hinges can introduce an efficient damping in the deployment that can guarantee a controlled maneuver.

The following activities shall be accomplished:
 
  • State of the art review and establishment of application rang.
 
  • Selection of demonstration application for replacement of existing technologies. The application to be selected shall be a qualified part/subcomponent on an existing, qualified, space product.
 
  • Design and materials trade-off, including fibre and resin system, and preliminary design.

    The activity shall be performed with the following steps:
     
    • Identification of a relevant existing structural panel with various subsystem functionalities attached, e.g. thermal control, AOCS and OBDH units, etc.
     
    • Redesign of the panel and the attached functionalities as multifunctional structure panel where the non-structural functionalities are integrated into the panel.

      Proposed activities:
       
      • Assess and identify the limitations of the commonly used approach for strength verification of composite laminates under cryogenic thermo-mechanical environment (including modelling, failure criteria with supporting test methods to determine allowable values).
      • Assess relevance of stacking sequences of plies in the laminate for resistance against cryogenic thermo-mechanical loading.

        Motivation: This study aimed to develop promising robotic fabrication methodologies for a fibre-based in-situ robotic fabrication process, for application in a lunar habitat as an alternative to existing additive manufacturing methodologies. Previous work has verified that fibre composite fabrication processes are capable of a high degree of automation and structural performance.
