Enhancement of Loop Heat Pipe (LHP) Modelling Tool
The current Loop Heat Pipe (LHP) module is increasingly needed to support thermal control design and modelling activities for various missions such as Aeolus, MTG and ExoMars. It is fully operational but only for a limited number of LHP architectures and analytical scenarios and they do not cover current needs. The proposed activity aims to further develop and extend this module the following ways:
  • Tuning of the module to improve performance and steady state convergence.

    Generic AOCS/GNC techniques and design framework for Failure Detection Isolation and Recovery
    The activity will include the following tasks:
     
    • Critical analysis of customer's requirements evolution between fully segregated HW constraints for Safe Mode (traditional ESA approach)and authorised reusepending justifications.
     
    • Critical analysis of current AOCS/GNC FDIR complexity and proposals for simplification with equivalent coverage, including model-based approach orintelligent sensors.

      System impacts of propulsion Passivation

      Propulsion passivation is most of the time feasible for running missions, using thrusters and existing AOCS modes, whatever the number of tanks and for both monopropellant and bipropellant systems.
      For monopropellant systems the propulsion passivation may be:
      -Partial for tank(s) with membrane. All the hydrazine under the membrane may be depleted but the pressurant gas above the membrane cannot be depleted. The final tank pressure is close to typically 5 bars at the end of mission.

      IOD of techniques and technologies for M2M Telecom missions

      Generally speaking DIAMS has been an opportunity to secure the feasibility of the IOD in technical, programmatic and financial terms. More specifically DIAMS has allowed to define the end-to-end mission concept for this IOD, covering the design of various associated segments : Space Segment (Payload, Platform), and Ground Segment. Both interest and programmatic aspects have also been consolidated.

      - On the technical plane :
      Both the requirements and the design of the system have been refined to validate the IOD concept :
