Stratospheric optimisation Dr András Sóbester is engaged in wide-ranging research which aims to develop technologies for the design, manufacture and testing of complex scientific instrument platforms, in particular low cost, high altitude unmanned aircraft. Research area Dr András Sóbester is a senior lecturer in Aerospace Engineering in the Faculty of Engineering and Environment at the University of Southampton. Dr Sóbester has BEng and MEng degrees in Mechanical Engineering and Design and Manufacture respectively. He completed his PhD at the University of Southampton, where he joined the Computational Engineering and Design research group. His doctorate was on the application of statistical techniques to optimise aerospace systems and this influenced much of his later research work too. He devises computational models which reduce the dependency on expensive and time-consuming simulation techniques required in the development of complex systems. 62 PECM Issue 16 Dr Sóbester’s ideas have led to applications in aerospace systems, including the design of unmanned air vehicles that operate at a wide range of altitudes. His statistical methods have also been applied to recent work on climate modelling which attempts to isolate and optimise the factors which cause the greatest uncertainty in current models. Academy support Dr András Sóbester received a Royal Academy of Engineering Fellowship in 2007. The Fellowship supported research work on various aerospace projects, including research to minimise the negative environmental impact of next-generation airliners by reducing their noise signature. During the course of his Fellowship, Dr Sóbester’s research increasingly focused on issues surrounding the scientific exploration of the stratosphere. His ASTRA (Atmospheric Science through Robotic Aircraft) initiative at Southampton was set up to rethink the technology that takes scientific instruments into the stratosphere for earth science and meteorology research. “The aim is to have rapid and low-cost development and deployment of fully customised systems, avoiding the expense and complexity of current generic systems,” he said. At the same time, he developed computational optimisation techniques to analyse the parametric shapes which make up the external surfaces of aircraft. Using these models, aircraft designers can save testing time and
