Abstract

The present 'vortex-alone' distributed-vortex singularity method, which uses flat panels with linearly varying vortex strength, is used for the analysis of multielement airfoils. This technique avoids such drawbacks of extant methods as the use of multiple singularities and the need to represent the airfoil by a large number of points. The versatility of the present formulation is demonstrated by analyzing thin or cusped airfoils, as well as airfoils with two, three, or four elements for which exact results are available. As few as 20 panels are shown to suffice in the computation of pressure coefficients over a single-component airfoil.
