Prerequisites / Co-requisites
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.
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.

Indicative content includes:
The Atmosphere: The international standard atmosphere. True and equivalent airspeed
Aerodynamics of Aerofoils and wings: Aerofoil profile parameters, lift, drag, pitching moment, aerodynamic centre, coefficients, stall. Pressure drag and skin-friction drag. Effects of Reynolds number (briefly). Wings, effect of aspect ratio. Trailing vorticies, downwash and induced drag. Multi-element aerofoils/wings, flaps and leading-edge devices. Effects of Mach number. Swept wings.
Propulsion: Jet engines, the effect of altitude. Turbo prop. Aerodynamics of propellers.
Aircraft performance: Steady level flight. Drag-speed relationships, minimum drag. Lift-to-drag and other non-dimensional ratios. Range and endurance for thrust producing engines. Rates and angles of climbing flight, thrust-producing engines. Altitude ceiling. Gliding flight. Ground effect, take off and landing.
Stability: Longitudinal static stability conditions, effects of downwash. Neutral stability and static margin. Speed control and trim. Longitudinal dynamic stability. 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)
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
An assignment (6 hours)
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 coursework 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:
Written assignment. (6 hours)
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 coursework assessment, and general points are fed back during lecture or tutorial time.
