In year three your research project allows you to tackle a problem in detail, such as the automated landing of an unmanned air vehicle (UAV), design of a potential space mission, or experimental testing of advanced composite materials. In year four there is greater flexibility for you to pursue options that interest you. Some units relate to particular application areas, such as helicopter aerodynamics, space systems or wind power. Others study particular technologies, such as composites analysis or experimental aerodynamics or you can choose to undertake a research project. The diversity of topics in aerospace engineering makes this a challenging degree but the reward is a uniquely broad education.
