What you will learn

On successful completion of this module a student should be able to:

Knowledge and Understanding:

  • Evaluate the structural design principles for GW systems.
  • Analyse the influences of vibration and aeroelasticity, and evaluate the principles of thermodynamics and gas dynamics on a GW design.
  • Analyse the operating principles and key component design features of air-breathing propulsion systems for GW, including turbojets, turbofans and ramjets.

Skill:

  • Perform preliminary-level structural design and stress analysis.
  • Analyse a GW aeroelastic mechanical design.
  • Critically evaluate the key GW design trade-offs which relate to structures, vibrations and aeroelasticity.
