Aims

The aims of the course are to:

• write a Matlab code that calculates the lift and drag on a 2D aerofoil section;
• design high-efficiency aerofoil sections, using numerical calculations to guide the process;
• gain an understanding of the aerodynamics of aerofoils, in particular the role of the boundary layer in limiting performance;
• obtain an appreciation of the strengths and weaknesses of CFD itself.

Content

The advent of high-performance computing has radically changed the aerospace industry's approach to wing design. In the past, wing sections were based closely on one of the wide range of standard geometries for which experimental data were already available, and optimisation was via extensive wind tunnel testing. Now, most initial section design is based on numerical calculations, with experimental work appearing later in the process. The advantage of this combined approach is that the experimental data which is the backbone of any development project is still obtained, but expensive wind tunnel tests can be targeted on the most promising designs identified by the (relatively) cheap computations. This computer-based project provides an introduction to the numerical design process, in the context of two-dimensional aerofoil sections for aeroplane wings. Programming experience above and beyond Part I computing coursework activities is not necessary.

Week 1

Write a 2D potential flow panel method. Validate via comparison with analytical solutions for standard test cases. First interim report.

Week 2

Write an integral boundary layer equation solver. Validate via comparison with theoretical and empirical results for laminar and turbulent boundary layers. Second interim report.

Weeks 3 & 4

Combine the potential flow and boundary layer routines to produce an aerofoil analysis code. Design your own 2D aerofoil sections using calculation results to guide the process. Final report.

Aims

The aims of the course are to:

• To introduce students to the challenges of designing and innovating with technology in the context of international development.
• To provide students with opportunities to improve their hardware and software rapid prototyping skills.
• To develop students' skills with project development, open collaborations and documentations writing.

Content

The IIA project Technology for the poorest billion allows students to work on real-world engineering related projects that are proposed by partner organisations and/or research labs, with the objective to address humanitarian challenges and contribute to international development.

Students will be offered to contribute, as a team, to one of the selected projects. They will work with great autonomy with the partner to propose, implement and test a solution to their problem. The project assessment is aligned with this overarching objective. Students will have to determine what they feel they can achieve within the duration of the project, and propose a work plan by the end of the first week.
Then students will have another two weeks to work on implementing solutions, deliver an interim presentation, and finalise their output (prototype and/or source code, handover notes, documentation, dissemination plan) in the last week. Feedback will be given during regular progress meetings with the project coordinators.

Students will be working in the Dyson Centre where possible, and a limited budget will be available to them to create their prototype. Principles of interdisciplinarity, creativity, openness and collaboration are key to successful international development projects. Students from all areas of engineering are welcome to join this team-based activity where complementary skills are an asset.

The project is developed and offered in collaboration with the Centre for Global Equality.  

ACTIVITIES

1. Around the end of Lent - 2h afternoon session (date/time tbc) : Lara Allen, Director of the Centre for Global Equality, will present some of the most pressing challenges faced by the poorest billion on the planet, and cover a number of success stories, but also highlight failures and works in progress.

2. Start of IIA project period - allotment of team project :  to be determined with partners.

3. Project Week 1: Developing a proposal including costing. Identifying team strengths and weaknesses, setting up work-plan and roles for the project development.

4. Week 2/3: Early prototype development.

5. Week 3: Interim presentation, preliminary feedback from judging panel.

6. Week 3/4: Development of final prototype, project report, online documentation et video demonstration.
