  • EG-M90 Advanced Aerodynamics

    This module is intended to extend the theory of EG-293 Aerodynamics & EG-335 Gas Dynamics and apply it in the context of aerodynamic design across a range of length scales and Mach number. A number of case studies will be used to explore the concepts of aerodynamic design ranging from subsonic civilian aircraft to aerodynamic design in nature and hypersonic space vehicles. The course is split into four sections: subsonic, transonic, supersonic and hypersonic. By the end of the course students should have developed a good understanding of why aerospace vehicles operating in these different speed regimes with varying mission objectives look the way they do from an aerodynamic perspective.

  • EGA302A Aerospace Engineering Design 3

    The module is a group design project for year 3 aerospace engineering students. Students are required to design an aerospace vehicle from an initial set of mission requirements and constraints through concept design to detailed design and flight testing. It requires students to draw on knowledge from a range of modules across the aerospace engineering course. Each student will specialise in one of six areas: aerodynamics, structure, materials & propulsion, weight& performance, control systems or dynamics & stability. Groups will be required to submit a series of group design reports at each stage in the design process as well as deliver presentations to the rest of the class. Each student will also take a turn acting as chief engineer and a reflective essay is required after the student's time as the chief engineer. By the end of the module students should have an understanding of the process and complexities involved in designing an aerospace vehicle from scratch and appreciate the multi-disciplinary nature of this task. Note that since this module is, in part, explicitly assessing students' ability to work effectively within a team environment the group submissions and peer review components of assessment cannot be excluded for extenuating circumstances.

  • EGH303 Aerodynamics

    This module extends the previous coverage of Fluid Mechanics and covers the fundamental equations governing aerodynamics and their application to aeronautical systems. Various analytical and computational methods of solving aerodynamic problems are covered. This will lead on to considerations of stability and instability in aircraft flight.

  • EGTX23 Engineering in Texas and CAE for Texas Exchange Aerospace Engineers (replacing EGA230)

    This module is for Aerospace Engineers undertaking the Texas A&M exchange programme. It replaces EG-264 (Computer Aided Engineering) and is split into two parts: 1) An analysis of the differences between studying engineering in the UK and in the USA (5 credits) Students will be required compare and contrast studying Aerospace Engineering in the U.S. and the U.K. in terms of course content, academic culture, student life and social culture. This will be assessed in two parts; a group presentation and an individual report. Both of these will be assessed after the students return to Swansea from the exchange. 2) An introduction to SolidWorks Students will be required to complete a self-guided coursework assignment which introduces them to SolidWorks CAD software. The assignment will require the students to design a specified aerospace component and produce a report explaining the design process and their use of the SolidWorks software.
