AERODYNAMICS & FLIGHT MECHANICS - 2023/4

Module Overview

The purpose of the module is to introduce the student to aeronautical aerodynamics, the aerodynamics of aerofoils and wings, aircraft propulsion, and to apply these to build an understanding of and mathematical description of aircraft flight for low-speed subsonic aircraft.

Module content

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, aerodynamic coefficients, stall. Pressure and friction drag. Effects of Reynolds number (briefly).  Wings, effect of aspect ratio.  Trailing vortices, downwash, and induced drag.   Multi-element aerofoils/wings, flaps and leading-edge devices.  Effects of Mach number. Swept wings.

Propulsion systems: 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).

Assessment Strategy

The summative 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 students to develop their 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 hr) - [learning outcomes 1, 3]


• Examination (2 hrs) - [learning outcomes 1, 2, 3]

• Formative verbal feedback is given in tutorials during discussions with individual students.


• Written feedback is given on the class test, and general points are fed back during lecture or tutorial time.


• Further feedback is provided during the laboratory classes.

Module aims

• Provide students with an introduction to the principles of flight and their implications for low-speed subsonic aircraft
  
• Provide students with a level of understanding that will equip those seeking professional placement where a knowledge in aerodynamics and the principles of flight is expected
• Provide students with sufficient knowledge to participate in the Flight Test Course at a later time, though this course is not formally part of the module
• Provide students with a practical experience (via laboratory classes) of aerofoil aerodynamics and aircraft stability
• Provide students with an introduction to propulsion systems used in the aerospace industry

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to introduce principles through theory, delivered primarily through guided learning. This is accompanied by tutorial example sets, some of which develop a series of linked case studies.

The learning and teaching methods include:

• 3 hours lecture per week x 11 weeks


• 1 hour tutorial (in groups) x 10 weeks


• 3 hours of Laboratory experience

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.
