AERODYNAMICS & FLIGHT MECHANICS - 2021/2
Module code: ENG2091
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
The purpose of the module is to introduce the student to aeronautical aerodynamics, the aerodynamics of aerofoils and wings, and to aircraft propulsion, and to apply these to build up an understanding of and mathematical description of aircraft flight for low-speed and subsonic aircraft.

Lateral control and static stability. Longitudinal and lateral stability derivatives. Effects of control surfaces, wing shape; wing height and dihedral, sweep. Introduction to lateral dynamic modes.
Flight Test Course: Briefing, covering how parts of the module relate to this course (which is separate from the present module)
|Assessment type||Unit of assessment||Weighting|
|School-timetabled exam/test||ASSIGNMENT (1 HR)||20|
|Examination||EXAMINATION (2 HRS)||80|
The assessment strategy is designed to provide students with the opportunity to demonstrate an understanding of scientific principles, methodologies and mathematical methods as well as the ability to describe particular systems and processes in the final examination. The tutorial work allows the student to develop his/her understanding of the lecture material by a series of progressive questions. The class test element allows students to demonstrate that they can interpret problems and present solutions clearly and accurately.
Thus, the summative assessment for this module consists of:
- Class test (1 hour)
- Examination (2 hours)
Formative assessment and feedback
- Formative verbal feedback is given in tutorials in discussion with individual students.
- Written feedback is given on the class test, and general points are fed back during lecture or tutorial time.
- This module aims to provide students with:
an introduction to the principles of flight and their implications for low-speed and subsonic aircraft;
- a level of understanding that will equip those seeking professional placement where a knowledge in aerodynamics and the principles of flight is expected;
- sufficient knowledge to properly participate in the Flight Test Course at a later time, though this course is not formally part of the module.
- This is the first module specific to the Aerospace Engineering taken by students on these programmes, and also provides an introduction to material that is covered in later modules.

Overall student workload
Independent Study Hours: 104
Lecture Hours: 35
Tutorial Hours: 11
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
introduce principles through theory, delivered primarily through the lectures. The lectures are accompanied by tutorial example sets, some of which develop a series of linked case studies.
The assignment picks on a number of topics that have been covered to that point, with feedback given individually and general points to the whole cohort.
The learning and teaching methods include:
- 3 hours lecture per week x 11 weeks
- 1 hour tutorial (in groups) x 11 weeks
- 2 hours revision via questions from past exam papers
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
