Problem Definition: The possibility of assessing environmental sustainability of future launchers from the early design stage depends on the availability of simplified and fast but accurate models, which have been developed, at the moment, only for traditional subsonic aviation. There is the urgent need to develop analytical formulations able to predict chemical emissions from a wide range of vehicle configurations, engines architectures and propellants.
Research Objectives:
- Definition of an exhaustive taxonomy of future launchers, and creation of a structured database
- Modelling and simulation of the most promising rocket engine architectures from a thermodynamic standpoint
- Numerical and experimental examination of combustion processes
- Definition of analytical formulations for chemical emissions predictions
- Integration of the novel formulations in commercial launchers and missions design tools
- Launcher configurations comparison and trade-off
Expected Results:
- Ability to assess the influence of launchers configurations, technologies and concept of operations on chemical emissions production
- Numerical propulsive and emissive databases, validated, when possible, against experimental tests
- Novel analytical formulations to predict chemical emissions in conceptual design
Secondments:
- Astos Solutions GmbH (ASTOS, Stuttgart, Germany, ca. 4 months): Analytical formulation integration in the ASTOS software and testing
- Institut supérieur de l'aéronautique et de l'espace (ISAE, Toulouse, France, ca. 4 months): 1D and 2D chemical/kinetic combustion modelling and simulations and experimental validation
