In WP1, AVS has been coordinating the coordinating the consortium during the whole project execution. Progress Meetings for the monitoring of the work between each partners. Deliverables, presentations, 2D, ... have been uploaded to a sharefolder, periodic reports have submitted to the EC.
In WP2, the study of the art was analyzed and requirements for the active antenna and the MPL EQM where defined.
In WP3, the trade off and selection of the pump for IMPACTA was completed. AVS's pump (PDPump) was the only one available for the system, as there are not space pumps at the moment in EU. The trade-off and preliminary design of the evap. and the EQM itself were also done. Ammonia was selected as the working fluid for IMPACTA.
In WP4, the EQM was detailed designed and the procurement of LLI started. Some evaporator prototypes were manufactured and tested.
In WP5, the complete MPL has been manufactured and assembled. All the components have been procured. The electrical gabinet has been assembled and the cable routing done.
In WP6 Test Campaign and Conclusion:
- Two-phase MPL operation in all orientations is demonstrated for 10 kW power with margin.
- The evaporator design with passive flow restrictions in parallel evaporator branches demonstrates stable operation in all operational cases, including full imbalance cases with only one branch powered.
- The IMPACTA control works robustly in all cases including P/L start-up, sudden P/L shutdown for both the primary and redundant evaporator branches
In addition, the roadmap for future activity to higher the TRL has been done, as well as the study of application for other payloads.
Regarding WP7, the consortium has participated in different conferences and workshops. A webpage has been created:
https://impacta-mpl.com/(odnośnik otworzy się w nowym oknie) and papers published.
Finally, WP8 Exploitation and Commercial assessment has been completed in order to perform an study of the market and identify the best dissemination possibility.
In conclusion, IMPACTA has resulted in a successful project on which all the specific objectives of the project have been achieved. IMPACTA has survived to the unexpected external impacta (coronavirus) in 2020 and also to the war between Russia and Ucrania, which in the last period has increased the cost of the materials and generated delays in transportation. The equipment has been manufactured and the test campaing has been executed (performance testing). In addition, the thermal vacuum & vibration testing has been performed to the PDPump. During the project dissemination, activities have been carried out in order to advertise IMPACTA MPL. Different conferences & workshops have been attended. In addition, some papers have been published:
“Development of an Innovative Diaphragm Pump and Two-Phase Mechanically Pumped Loop for Active Antennas“
https://ttu-ir.tdl.org/handle/2346/89743(odnośnik otworzy się w nowym oknie) “Preliminary design of a mechanically pumped cooling system for active antennae“
https://ttu-ir.tdl.org/handle/2346/87033(odnośnik otworzy się w nowym oknie)A new publication is expected and will be presented in the ICES.
