Learning Outcomes
- Use a control volume to develop the equations, being able to understand the basic ideas of conservation used in the process, and then understand and be able to apply potential flow theory.
- Understand the characteristics of lift (and drag) in 2D and 3D, the key difference between them, and be able to apply lifting line theory and panel methods to determine the aerodynamic characteristics of lifting surfaces / aerofoils. (Capability 1.1, 2.1, 2.2 and 3.2)
- Understand and apply CFD to the solution of aerodynamics problems, use analysis and visualisation tools to reveal important flow phenomena, and understand / recognise the limitations of CFD. (Capability 1.1, 2.1, 2.2, 3.1 and 3.2)
- Understand the differences between low and high Reynolds number aerodynamics of aerofoils / wings, and be able to apply this knowledge to the design of lifting surfaces for gliders, UAV and larger aircraft wings. (Capability 1.1, 2.1, 2.2, 3.1 and 3.2)
- Understand and apply the concepts of lift, drag and moment to a flying aircraft, and therefore determine its stability in flight, and then be able to calculate the performance of an aircraft from a knowledge of its aerodynamics, and the propulsion. (Capability 1.1, 2.1, 2.2, 3.1 and 3.2)
- Analyse compressible flow situations to determine shock strength, pressures, flow rates etc; and then be able to understand and apply knowledge on supersonic flight. (Capability 1.1, 2.1, 2.2, 3.1 and 3.2)
- Understand, recognise and explain bluff body (including building) aerodynamics and use these to determine pressures and loads, additionally when the building is immersed in the atmospheric boundary layer flow. (Capability 1.1, 2.1, 2.2, 3.1 and 3.2)
- Understand and be able to analyse wind turbine blade aerodynamics, be able to quickly size a wind turbine to produce a specified power in a specified wind regime. (Capability 1.1, 2.1, 2.2, 3.1 and 3.2)

Health & Safety
Student Feedback
At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.
Your feedback helps teachers to improve the course and its delivery for future students.
Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.
Academic Integrity
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.
Class Representatives
Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.
Inclusive Learning
All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.
Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz
Special Circumstances
If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.
If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.
This should be done as soon as possible and no later than seven days after the affected test or exam date.
Learning Continuity
In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.
Student Charter and Responsibilities
The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
