Module code: ENG2096

Module Overview

Second year module for BEng and MEng aerospace engineering students.

A lecture and tutorial based module giving understanding of aircraft structures, aircraft aerodynamic loads and aeroelasticity. This builds on previous general modules on materials stress analysis and the module on aerodynamics and flight mechanics, providing the student with knowledge and understanding in each of these areas directly applicable to aircraft structures. It complements this knowledge with an introduction to fluid-structure interaction, presenting fundamental loads and aeroelastic effects that arise on aircraft structures.

Alternative Assessment


Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

they can describe aspects of typical aircraft structures and hence the rationale for their idealisation
they can analyse simplified aircraft structures through hand calculations
they can calculate shear flow distributions in thin-walled beam sections
they can describe the implications of fluid-structure interaction on aircraft analysis and design (final examination)
they can perform basic aerodynamic loads-related and aeroelastic hand calculations on simplified examples

Thus, the summative assessment for this module consists of:

Examination [Learning outcomes 1, 2, 3, 4]          (2 hours)        {100%}

Formative assessment and feedback

Formative assessment - practice exam style questions - peer marked
Formative verbal feedback is given in lectures (group) and tutorials (individual)
Written feedback is given on the coursework (individual)

Module aims

  • an introduction to typical materials and features of (principally fixed-wing) aircraft structures and methods of stress analysis based on hand calculations
  • an understanding of the interaction between aerodynamic loads and structural deformations, as well as an introduction to the most important aeroelastic effects on aircraft

Overall student workload

Independent Study Hours: 106

Lecture Hours: 33

Tutorial Hours: 11

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce aircraft structures, materials and aeroelasticity principles through theory and worked examples. This is delivered through lectures and tutorial classes.

The learning and teaching methods include:

3 hours lecture per week x 11 weeks
1 hour tutorial (in groups) x 11 weeks


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.
