Background
General Background
Alistair Saddington is Professor of Defence Aeronautics at Cranfield University, Shrivenham and Head of the Centre for Defence Engineering and Physical Science.
Alistair's main research and teaching interests are in aerodynamics including computational and experimental methods, as well as engineering design and optimisation. He has over 25 years of experience in aerospace engineering across both industry and academia including research leadership, management, and postgraduate teaching and supervision.
Alistair has a First Class BEng (Hons) degree in Aeromechanical Systems Engineering from Cranfield Institute of Technology (now Cranfield University). and an EngD, also at Cranfield, for research on short take-off and vertical landing (STOVL) aircraft propulsion integration aerodynamics. Following a short period in industry with Rolls-Royce Bristol, where he worked on a range of compressor aerodynamic design and research topics, he returned to academia and joined Cranfield University, Shrivenham. Alistair led the development of the University's part-time MSc programme in Military Aerospace and Airworthiness (MAA) and is the current Course Director. He is a Chartered Engineer, a Fellow of the Royal Aeronautical Society and Member of the Special Interest Group on Weapons Science and Technology.
