A continuous vorticity panel method for the prediction of steady aerodynamic loads on lifting surfaces

A continuous vorticity panel method is developed and utilized to predict the steady aerodynamic loads on lifting surfaces having sharp-edge separation. Triangular and semi-infinite panels with linearly varying vorticity are used. The velocity field generated by an individual element is obtained in c...
