	abstract = {In  this  paper  we  follow  the  process  of  rapid  design improvement  for  the  fan  outlet  guide  vane  for  a  turbofan powering a very light jet. The small size of such engines leads to  a  low  Reynolds  number,  resulting  in  flow-fields  prone  to boundary  layer  separation,  causing  significant  losses  in efficiency. This paper studies experimental testing in a scale rig, and numerical simulation using CFD, leading to the comparison of  the  two  datasets  and  hence  assessment  of  the  numerical technique.  The  mesh  employed  by  the  CFD  simulation  was modified  using  Free  Form  Deformation  to  create  different geometric  designs,  and  hence  an  optimization  scheme  was subsequently  utilized  to  find  the  deformation  of  28  variables which  maximized  aerodynamic  performance.  The  final optimized  design  displayed  a  novel  oscillatory  casing  profile, while  the  blade  shape  had  increased  camber  relative  to  the baseline. The improvement in pressure loss was approximately 20\% across the range of operating conditions studied.},
