The module will be delivered with a blend of lectures, tutorials and problem-based learning with laboratory sessions, and individual self-directed research. This will include case study exercises and demonstration videos.
Module Aim:
The aim of this module is to introduce learners to the fundamental theories of aircraft stability and control, and how to apply techniques to predict and analyse an aircraft's stability, control and handling characteristics.
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1
Recognise the aircraft design characteristics that influence its stability and control properties.
LO2
Formulate the equations of motion for an aircraft in 2D flight, with focus on the stability and control derivatives.
LO3
Numerically predict and analyse the static and dynamic stability of an aircraft.
LO4
Analyse the operation and performance of a feedback control system using computer simulation techniques.

Practical/Skills Evaluation
Students will carry out a number of laboratory sessions throughout the academic year to enhance their understanding of the module, and will produce written reports describing each one. Laboratory practical work will include investigation of the following topics: static and dynamic stability analysis; computer simulation tools and mathematical modelling; real time flight analysis. A number of these laboratory sessions may take place in a simulated and/or a live aircraft flight environment.
