Description including Unit Aims

The aim of this unit is to bring together elements of flight dynamics and control theory into the context of aircraft design and response.

After a brief revision of aircraft equations of motion and response modes, the equations of motion are converted to transfer function format in order to perform (mainly) single-input-single-output control design.

Types of aircraft control and the importance of aircraft-pilot coupling and pilot handling qualities for aircraft manoeuvre demand systems are then discussed.

Common aircraft feedback structures are then developed, with emphasis on manoeuvre demand systems, along with relevant filtering and compensation techniques and examples for real aircraft (A320, EAP). Influence of typical non-linear and structural mode interactions are described and an extended numerical example is analysed.

Modeling, analysis and design of multivariable control systems in state-space form are described.

Fundamental properties of discrete (digital) implementation of control laws are introduced.


Sources of non-linearity in flight mechanics are described, along with associated aerodynamic and inertial phenomena and resulting flight dynamics behaviour. Implications for both agile/manoeuvrable aircraft and airliner upset are discussed.

Intended Learning Outcomes

On successful completion of the unit the student will be in a position to:

- design and evaluate simple linear aircraft controllers, using transfer function and state space methods, to account for manoeuvre demand requirements, stability and handling qualities, basic implementation issues (including some fundamentals of digital controllers) and limitations associated with actuators and filters;

- understand the sources of non-linearity in flight mechanics at high incidence and the associated challenges;

- perform simple analyses of aircraft response to discrete and continuous atmospheric disturbances.

Teaching Information

Teaching will be delivered through a combination of synchronous and asynchronous sessions, which may include lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

Assessment Information

100% Summer exam

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. AENGM1300).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
