Subject fundamentals
Within the educational growth of students in Aerospace Engineering with particular emphasis on Systems Engineering, the present course represents the final synthesis for "aerospace systems integration", as at the same time the single system (or subsystem) is considered and designed to be an harmonic integration of equipment and to be able to perfectly integrate with all other systems (or subsystems), which are both on board and outside the vehicle, like the Logistic Support System. Apart from these systems, an innovative concept, the so called System of Systems, is getting more and more important today and it has to be seriously taken into account, as there is a growing interest and need to make various types of systems operate together in an integrated way.
A fundamental objective of the present course is therefore represented by the development of the capability of learning the Systems Engineering view and approach to design, in order to make the students able to define and integrate subsystems and/or components to form a system that meets requirements. Students will therefore learn how to size subsystems and components and how to evaluate and compare architectural layout alternatives, through the application of the typical Systems Engineering design tools. While the first part of the course focuses on issues related to the definition of integrated aerospace systems, specifically from the point of view of functions/performance, the second part of the course focuses on the peculiar features of the various subsystems, from the point of view of sizing and qualitative or architectural choices, including considerations on Safety, Reliability and Maintenance. The role of integration is fundamental both in the first and in the second part of the course. In particular in the second part of the course integration plays a crucial role for installation studies and for considerations on Logistic Support System.
Expected learning outcomes
Capability of performing systems engineering design activities at different levels as well as acting as Logistic Support System designer, taking into account systems integration, Systems Engineering design tools, technical products data searching and evaluation and reporting.
Prerequisites / Assumed knowledge
Fundamentals of aerospace systems, flight mechanics, aeronautic constructions.
Contents
Course introduction and schedule. Examination. Course table of contents. Systems configurations of some modern aircraft. Systems design methodology: requirements analysis, functional analysis, definition of integrated systems architecture, preliminary sizing, mathematical modeling, weight and volume estimation. Requirements integration at system level and definition of subsystems requirements. Example: aircraft architectural layout definition, conceptual sizing and subsystems definition (30 hours).
Definition of main aircraft subsystems: avionics, flight controls and landing gear, fuel system, Environmental Control system, anti-ice system, air system, hydraulic and electric system; integration of subsystems and definition of main equipment. Subsystems installation studies. Presentation of a software tool for on board integrated systems design and related applications (30 hours).
Fundamentals of systems integration. Digital Mock-Up at Conceptual Level. Safety, Reliability and Maintenance in Systems and Integrated Logistic Support System Design. Installation analysis and Zonal Safety analysis. Preliminary cost estimation (20 hours).
Delivery modes
Design exercise: students are divided into groups and each group is in charge of carrying out the system design of a specific vehicle. Main steps of the design exercise are:
- conceptual definition of the aerospace platform
- architectural configuration definition and 3D CAD modeling
- subsystems definition
- integration of subsystems for digital mock-up
- application of maintainability and safety analyses (Zonal Safety analysis) to digital mock-up and cost evaluation
Even though the students will work in a group, each student has to participate to all phases, in order to acquire the capabilities needed to perform each step. Design reviews are planned in advanced and related presentations are envisaged, in order to let the students able to learn issues related to other students team work and their proposed solutions.

- Exercitations: the students, that attend the course, will be provided with the texts of the proposed topics and their solutions through the educational portal.
Assessment and grading criteria
The examination will focus mainly on the evaluation of the system design performed by the student during the course, on the basis of the report written by the student on the assigned design theme. The examination will also focus in the design activities carried out by the other students teams. The examination aims at verifying the knowledge acquired by the students on issues related to aircraft systems design and the capability of students to explain clearly, rationally and synthetically the results of their technical activity.
