The overall system analysis is shown as depending on the high pressure required to have high efficiencies, also towards an improved sustainability of space propulsion. The goal is also to provide the basic elements for the study of turbomachines in general and the main aspects of combustion instabilities in liquid rocket engines.

Educational objectives

The course will be devoted to the analysis and modelling of solid rocket motors and the complex phenomenology that characterizes these propulsion systems. Theoretical and mathematical models will be provided for analyzing the operation and performance in the quasi-steady regime with both zero-dimensional and one-dimensional approaches. Combustion of energetic materials will be analyzed with attention to the various solid propellant formulations. Specific aspects such as ablation phenomena of thermal protection materials in the nozzle, two-phase flow phenomena, grain geometry and burn-back analysis, as well as ignition transient, will be analyzed in detail. Hints on hybrid rocket propulsion systems and their main characteristics will be given. Finally, attention is given to recent efforts devoted to developing solid propellants using green oxidizers, which demonstrate less hazards and environmentally friendly chlorine free combustion products.

Educational objectives

One of the greatest difficulties encountered in the practical use in terms of engineering applications of computational fluid dynamics is the competitiveness of tasks, and related problems, which are by their nature very different. To name a few: the choice of computational mesh, solution algorithm, turbulence model, etc.

Therefore, the training objectives will focus on the knowledge and understanding of a broad spectrum of numerical methods, physical models and analysis techniques relevant to aerodynamic design in the compressible regime, as well as on the acquisition of the ability to identify the physical problem of interest, the choice of an appropriate approach for numerical modeling and the critical evaluation of the results obtained.

In addition, great emphasis will be placed on a project, hopefully a group project, aimed at the solution/simulation of a specific problem. This will address virtually all phases of the CFD workflow, pre-processing, resolution and post-processing. The team will have to organize meetings, manage resources, handle task dependence, report on calculations, and conduct comprehensive analysis.

The group project is central to this course, as it creates a virtual consulting environment, bringing together students with diverse backgrounds to solve a real problem.

Problem solving and project coordination must be undertaken on an individual and team basis. Students will also develop interpersonal skills needed to pursue their future careers as engineering and technology leaders.

At the end of the project, the team will give a presentation in which they will outline the problems encountered and the results achieved.

Educational objectives

Before entering the master of science program, aerospace engineers are already acquainted with the basic principles of fluid motion being trained on fundamental aspects of aerodynamics and gas dynamics. This level of knowledge is however deeply insufficient to understand how, even ordinary, fluids, such as air and water, behave in low gravity. The reduced weight adds indeed to the complexity of fluid behavior and enhances the effects of forces like surface tension that are usually negligible at the human scale on the Earth. In addition to that, the long permanence in the restricted environment of the spaceship, or, respectively, inside habitation modules, requires confidence with the more complex physiological fluids, and an understanding of how rheologically exotic fluids may behave.

In this framework, the course in microgravity flows is dedicated to providing the students interested in the microgravity environment with the appropriate tools to understand and design fluidic applications for and in the context of space sciences. The overall purpose is to train the students to identify the challenges posed by fluid motions in space systems and to propose effective solutions to problems involving their dynamics in the context of payload design, onboard systems, and manned missions.

- Capacity to translate the mathematical models of fluid motion into computational algorithms.
- Capacity to perform numerical simulations and interpret the results.
