Problem Definition: Key challenges to full launcher sustainability are the capability to achieve full reusability throughout the design of a reusable upper stage, and the environmental impact integration into the definition of the launch system and the end-2-end launch mission.
Research Objectives:
- Definition of a suite of low-fidelity models to estimate emissions
- Definition of the mission engineering solutions for different concepts of operation (CONOPS) aiming at the minimisation of the emissions while achieving the reference mission objectives
- Preliminary quantification of emissions, trade-off of the CONOPS identified and derivation of the most promising solution for given payload classes
- Development of a re-entry and recovery architecture missionisation strategy, process and tool for use in future reusable launchers
Expected Results:
- A validated suite of low-fidelity models for emissions estimation in the context of atmospheric re-entry
- Definition of a mission engineering methodology and process that integrates an ecodesign approach into the design of atmospheric re-entry for reusable upper stages with respect to specific payload classes
- A re-entry and recovery architecture missionisation tool that supports the design of sustainable launchers
- The application and validation of the process and tools on representative study case scenario(s), performed making use of different high-fidelity models in successive steps
Secondments:
- Politecnico di Torino (POLITO, Torino, Italy, ca. 5 months): definition of low-fidelity models
- Office national d'études et de recherches aérospatiales (ONERA, Palaiseau, France, ca. 4 months): multi-disciplinary optimisation
