  • Non-axisymmetric aero-engine nacelle design by surrogate-based methods 
    Tejero, Fernando; Christie, Robert; MacManus, David G.; Sheaf, Christopher T. (Elsevier, 2021-06-15)
    For many aerodynamic design tasks, a key challenge is the balance between the non-linearity of the transonic flow, the inherent 3D nature of the geometry and flow field, the computational cost and the level of accuracy. ...
  • Surrogate model of complex non-linear data for preliminary nacelle design 
    Heidebrecht, Alexander; MacManus, David G. (Elsevier, 2018-10-03)
    Most response surface methods typically work on isotropically sampled data to predict a single variable and fitted with the aim of minimizing overall error. This study develops a metamodel for application in preliminary ...
  • Surrogate models for the prediction of the aerodynamic performance of exhaust systems 
    Giangaspero, Giorgio; MacManus, David G.; Goulos, Ioannis (Elsevier, 2019-05-14)
    The aerodynamic performance of the exhaust system is becoming more important in the design of engines for civil aircraft applications. To increase propulsive efficiency and reduce specific fuel consumption, it is expected ...
  • Surrogate-based aerodynamic optimisation of compact nacelle aero-engines 
    Tejero, Fernando; MacManus, David G.; Sheaf, Christopher T. (Elsevier, 2019-05-29)
    Genetic algorithms are a powerful optimisation technique for the design of complex engineering systems. Although computing power continuously grows, methods purely based on expensive numerical simulations are still challenging ...
