Abstract
Suction through porous aircraft wings is a promising concept to reduce its drag, but the modified boundary layer can be more susceptible to external forcing, like surface roughness and inhomogeneities in the suction distribution. This paper analyzes the effects of suction on the linear receptivity of a swept-wing boundary layer to surface roughness and non-uniform suction, focusing on stationary crossflow instabilities. Employing a compressible adjoint approach, receptivity coefficients for a Falkner-Skan-Cooke similarity solution and a transonic swept-wing boundary layer on an A320 vertical tail plane with and without suction are given.
