Material compatibility with ammonia is critical for the performance and lifetime of Two-Phase equipment. The generation of non-condensable gases can severally impact the performance of the two-phase equipment. Material compatibility testing is mandatory in all the development of two-phase equipment which uses new materials. However, the compatibility results are not publish and it remains at the manufacturer, hence it cannot be used by another manufacturer.

Additive manufacturing (AM) is developing at an impressive pace, especially for mission critical components like combustion chambers and turbopumps. However, new inspection methods during manufacturing become a necessity as failure of such components leads to a failure of the entire launch vehicle.

In the course of this project, authors have developed an additive manufacturing technique firmly rooted in the Powder Bed Fusion methodology, specifically designed to address the challenge of Off-Earth Manufacturing. The unique aspect of the technology lies in the utilization of a specialized feedstock material in form of a colloidal mixture. This material has the remarkable capability to create a rigid and stable powder bed, making it exceptionally well-suited for operation in zero-gravity conditions.

The lunar environment has a challenging dust environment. The dust is highly abrasive and therefore can cause considerable damage in short time. For astronauts, the dust effects range from highly irritating to toxic. Many sample processing and sample analysis systems need reliable seals; spaceflight hardware must work reliably in the presence of dust.

Aerobraking phase of ENVISION is critical in terms of duration and required operations. One limitation during aerobraking is the temperature reached on Multi Layer Insulation (MLI) due to the aerothermal heat flux.MLIs can withstand during short durations (intermittent exposure) higher temperatures than their steady state qualification temperature.

A PCM provides a temporary cooling capability of electronics boxes when overheating/absence of effective cooling leads to over-temperature for any type of spacecraft or launcher. The proposed technology saves mass vs traditional heat sinks for applications where high power dissipation occur for a short period of time.
The activity shall focus on the following points: ?
 
  • Radiation resistance of organic PCM?s: samples and whole PCM box, needing a large quantity of PCM to be irradiated under p and gamma

    The concept of digital twins in industry relates to the development of data models for physical systems to accurately reproduce physical and performance characteristics of processes and products. It is often referred to as a virtual replica of the physical asset which can be used to monitor and evaluate its performance. In the scope of Industry 4.0, the digitalization of manufacturing processes bring significant potential in the improvement, namely in lowering manufacturing costs, improving performances, increasing reliability, and in reducing the time to market.

    The documents describe the first work developed by Maana Electric in the frame of the ACME project. The aim of the activity is to develop a system to use thermite reaction produced from in-situ resources from lunar regolith and use the energy released by the metallothermic reaction as a Lunar Night Survival solution. These documents report the results of the first Proof-of-Concept car laboratories to validate that thermite in atmospheric condition can be generated from regolith and its beneficiated forms. From the outcomes of the PoC, a breadboard has been designed, integrated and tested.
