Aerospace Vehicle Design

Module aims

The design of aerospace vehicles is a complex, multidisciplinary endeavour. This module offers you an opportunity to integrate and apply your prior knowledge and analytical skills to the design of an aircraft of conventional architecture, starting from only a simple set of operational requirements, while introducing them to the multi-stage approach and methods typically employed by vehicle design teams.

Learning outcomes

On successfully completing this module, you should be able to:

  1. appreciate the importance of the design process for the overall future success of a new aircraft project;
  2. demonstrate understanding of the drivers and constraints, including operational, legal and environmental, in the evolution of a new aircraft configuration from an initial set of operational requirements;
  3. synthesize and apply their broad aeronautical knowledge to practical aircraft design problems through use of appropriate methodologies, tools and terminology;
  4. better recognise the order of magnitude of various design parameters;
  5. appreciate the relative importance of design choices, as determined by a problem's inherent level of uncertainty, as you progress thought the stages of a design project;
  6. tackle complex, multidisciplinary design problems where there is significant uncertainty;
  7. collaborate and communicate as a member of a small, multidisciplinary design team.

U/C loads etc.; Cut-outs design; Design of fatigue prone components, such as root fittings, spar boom splices, windows etc.; Practical fail safe and safe life design.; Finite Element analysis of airframe components; ESDU data sheets relating to structural strength, stability and fatigue.
 

Teaching methods

The module utilizes a project-based, student-centred learning approach, whereby you will carry out the project in a small group. While you will primarily learn through the conduct of the project itself, extensive support material is available in the form of pre-recorded online lectures, a wide variety of reference texts, weekly drop-in tutorials with the tutors and an online discussion forum.
