The complete lecture notes will be available via Blackboard. Further directed study will be supported by printed notes and guided readings. The laboratory sessions will involve experiments on two vitally important aspects of aerodynamics. There will be relevant soft wares available on campus networks and students will be encouraged to use them freely.

They must also produce a formal written report of the laboratory activity, outlining the suitability or otherwise of theory in practice and showing an awareness of the sources of experimental error, and drawing appropriate conclusions from the results. The assessments are designed to consolidate understanding of key aspects of propulsion and aerodynamics science and design RELEVAT to the 21 st century aerospace industry.. Aerodynamic analysis and design - this will involve identifying key physical mechanisms of operation and factors governing performance of wing components (winglets, slats, flaps, vortex generators etc) and aircraft body modification features e.g. nose cones, systems. Aspects of viscous flow, boundary layer theory, vortex models and drag/lift factors will be assessed to develop student learning of practical aerodynamic design. Students will also be expected to make recommendations for enhancement and innovation and quantify aerodynamic performance of different flight vehicles and its relationship to design and operating parameters, determine performance limiting factors with a focus on design regimes e.g. subsonic, supersonic etc. Propulsion analysis and design- students will be expected to comprehend, various types of propulsion system design e.g. jets, rockets, and will be assessed on integrating design formula, judgement and new recommendations for improvement of existing propulsion systems. This will also include cost factors, feasibility of combined designs e.g. hybrid bypass hypersonic systems (AJAX flight vehicle). Furthermore they will be expected to apply critical analysis to their new suggested designs and clearly show their conclusions based on quantitative and qualitative data, using a range of formats and media. The assessment will possibly also include alternative flight vehicles e.g. V-22 Osprey and new suggestions for improving helicopter propulsion. Students will be expected to identify sources of error and uncertainty for the investigation, develop and implement strategies for their reduction and validation, and be encouraged to use comparative. Presentations and reports for both areas discussed above will be coordinated by the module leader. For a pass (40%-60%) in the assessments, students will be expected to demonstrate a good ability to solve fundamental problems in aerodynamic/propulsion science, appreciate the applications and draw reasonable conclusions from their efforts. They
must also produce reasonably coherent laboratory reports on the Merlin Flight Simulator and Wind Tunnel. For a good pass (60%+) students are expected to demonstrate a much higher level of competence in calculations, incorporate critical analysis, make intelligent recommendations and also suggestions for improvements to particular aerodynamic/propulsion systems. The quality of written reports and research in assignments will also be expected to be very high and illustrative of the efforts of the student in developing an understanding beyond the basics. A separate reassessment package will be provided for students who are referred at first attempt. FEEDBACK Students will receive feedback on their performance in the following ways Feedback will be given during tutorial/seminar sessions where the students will have the opportunity to work through example problems, ask questions and will be encouraged to reflect on their experience. Feedback on assignments will be given in written format normally within 3 weeks of an assignment being submitted.
