An investigation is presented into whether Gurney flaps can provide increased lift on a configuration which is exhibiting transonic flow resulting from a moderate flight Mach number (M=0.6) and high lift condition. Of particular interest is whether any increment in lift can be sustained up to and beyond CLmax. The BAE Systems Hawk trainer configuration has been used as a demonstrator vehicle for this numerical study. SOLAR [1], the unstructured grid, Reynolds Averaged Navier Stokes, Computational Fluid Dynamics code has been used to provide the aerodynamic data upon which the analysis is based. A brief analysis is also presented of the increment in drag produced, but not for the change in pitching moment.
