Educational objectives The course gives a view of some space exploration systems with details
about the missions. The objective is to provide the basic elements of
aerospace engineering for analysis of exploration missions.

Educational objectives Knowledge and understanding;
At the end of the course the student will be informed about the following topics.
- How to get the thrust out of a propeller
- How does a turbo-prop work
- How does a piston engine work
- How to find an optimal design for a general aviation engine
Applying knowledge and understanding;
Ability to perform a preliminary sizing of the components of an aeronautical propulsion system, and estimate its performance through numerical tools produced by the students themselves during the group work.
The training objectives are pursued by using classroom exercises and work in progress reviews. The verification of acquired skills takes place during revisions and course lessons.
Making judgements;
The skills are acquired through frontal lessons, classroom exercises, and group work. The verification of knowledge is carried out through individual tests and through written group reports, which at the same time ascertain and promote the acquisition of the ability to communicate effectively in written and/or oral form.
Communication skills;
Ability to work in a team, to present the results of group work with presentations and short technical reports.
Learning skills.
Expertise to carry out a preliminary design of a general aviation engine powered by either a turboprop or a internal combustion engine. Ability to define a multi-objective design problem. Ability to use ModeFrontier, a robust, multi-objective optimization software.

Educational objectives The course objective is to introduce to the space systems design and
management of the system development. The global system design
problematics and the sub-systems sizing are addressedAttending the course, the space system design and management methodologies will be familiarized with.
In particular methods for the preliminary sysnthesis of a space systems requiremnts and development will be addressed.

Educational objectives The course aims to provide the tools to perform a simple static and fatigue design of an aerospace component, made in both metallic and composite material. The main transformation technologies used are described, both for the processing of metal alloys and composite materials, allowing an adequate contact with these materials and the knowledge of the most adequate way to use them in the structures. The main characterization, assembly and non-destructive testing techniques will also be addressed with a look at the materials and technologies of future aerospace structures.

Educational objectives During the course we will study the theoretical tools necessary for the design and optimization of the performance of aerospace vehicle trajectories. Their application to the various fields of Flight Mechanics and Astrodynamics (such as interplanetary missions or the ascent trajectories of Launchers), will allow the student, also through the development of software, to deal with mission analysis problem. Furthermore, the knowledge acquired will constitute a solid preparation for studying optimization problems in different fields of aerospace engineering.

Educational objectives Learning objectives of the proposed course consist of integrating general knowledge acquired in basic Aerodynamics course with more advanced and application skills. In particular, this course aims providing students with knowledge of principles and methods of applied aerodynamics, with reference to unsteady aerodynamics, to the study of the wake of aerodynamic and bluff bodies, of appendages and control systems and flows at small and large Reynolds numbers. The overall objective is therefore to delve into the aerodynamic optimization of components and of the entire aircraft, to introduce aerodynamic design and to apply some possible aerodynamic solutions to the study of aircraft and micro-air-vehicles. These objectives are obtained by specific theoretical knowledge, by analysis and optimization techniques and by practical examples through numerical and experimental investigations.

Educational objectives The optional course of the third year of the three-year degree in Aerospace Engineering (BAER) is designed to provide the student with knowledge and skills not currently provided for in the bachelor's and master's degrees. The current training offer is oriented towards training in the field of propulsion systems and other subsystems but there are no courses dedicated to the study of the launcher system. The course therefore provides an exhaustive overview of launch systems, aimed above all at understanding the process that defines the architectural choices and how these are governed by the choice of subsystems, passing through the study of the operating environment and the main physical processes involved. The launcher system is therefore not studied as the sum of its parts but, rather, as a multidisciplinary integrated design problem capable of stimulating the student towards a flexible and versatile use of the knowledge acquired in the field of aerospace propulsion.
The course program will be divided into the following topics:
History and development of launch systems, reusable and non-reusable launch systems, overview of existing launch systems; Ground launch systems vs air-launched systems; State of the art and problems of launch systems; Costs/benefits of launch base location.
Definition of launcher requirements and mission design; Dynamic, thermal, and acoustic loads on the launcher in the various flight phases; Aerothermodynamics of the launcher. Staging, tandem, parallel, and mixed architectures; design criteria for choosing staging and number of stages; Launcher performance curves (e.g., payload mass vs realized ∆V as a function of orbital parameters); Optimal distribution of ∆V as a function of the structural and propulsive efficiencies of the stages; Sensitivity analysis of propulsive and structural parameters on the launcher architecture. Recall of the concepts of velocity losses (gravitational, aerodynamic, and misalignment) and qualitative evaluation of their impact on the launcher's design choices.
Preliminary design of the launcher: integrated design aspects; architectural choices (number of stages and type of staging); dimensions and weights of the main components and subcomponents of the launcher, such as tanks, interstages, intertanks, fairings, fuel systems, turbomachinery, on-board avionics, control systems (thrust vectoring, jet vanes, jet injection, aerodynamic controls); Thermal protection systems; cost engineering analysis.
The Launch Systems course is structured according to the following descriptors of the skills that students will acquire.
Knowledge and understanding:
• Know how to evaluate the state of the art of launch systems, know recent and future technological developments and understand the current market landscape.
• Understand the fundamental principles of the integrated design of a launcher starting from the constraints represented by the mission and the general sizing, passing through the general system layout, the sizing of the masses and volumes of the main subsystems, the preliminary verification of the performances and the final integration of the launcher.
• Know how to critically evaluate the issues associated with the design of a launcher, including environmental impact, costs, reliability, and risk analysis.
Ability to apply knowledge:
• Know how to apply the methodologies acquired for the preliminary sizing of a launcher.
• Know how to develop simple calculation codes (e.g., Matlab) for sizing and calculating launcher performance.
Autonomy and responsibility:
• Know how to critically evaluate the advantages/disadvantages of different launch systems and the technologies associated with them.
• Know how to interact and collaborate in an interdisciplinary manner between groups of students with different tasks, in order to complete the integrated project of a launcher.
Communication Skills:
• Know how to produce detailed and coherent technical documents containing data, analysis results, descriptions of systems and subsystems inherent to the design of a launcher.
Lifelong learning skills:
• Acquire sufficient fundamentals of analysis and design of launch systems to allow both the continuous learning of coherent and similar topics, and the development of a decision-making process capable of efficiently complementing the student's career in aerospace engineering.
