Dr Andrew Limmack is Deputy Chief Engineer in the Aerospace and Defence team at the NCC with a specialism in the more unusual applications of composites, advanced materials and non-conventional testing. Having studied for a Masters degree in Aeronautical engineering from the University of Bristol he went on to undertake a PhD in the development and testing of nanocomposite materials for the protection of composite rotor blades in extreme environments. Following further research and teaching activities, Dr Limmack provided consultancy in reduction of defects and increasing the sustainability in composite manufacturing and assembly of civil aerospace and large wind turbine structures with a Bristol-based SME, in addition to playing an active role in European research council and UK Defence funded materials development programs including high rate, low cost composite manufacturing technology, multifunctional materials, testing and sustainable manufacturing processes. Alongside a lifelong passion for materials technology and propulsion systems, environmental responsibility and sustainability has become a fundamental driver behind his work.
