In the present investigation Low order panel method with Dirichlet boundary condition conjugated with Kutta
condition, was used to calculate pressure coefficients for potential flow about isolated curved wings at different aspect
ratios and different angles of attack. Also both local and total lift coefficients were calculated for the same wings, with
detailed streamline behavior on both upper and lower surface. Constant strength quadrilateral doublet element and
Constant strength quadrilateral source element were placed on each panel, except on wake sheet only constant strength
quadrilateral doublets were placed to satisfy Kutta condition at trailing edge. A set of linear algebraic equations were
established by setting inner potential equals to free stream potential. These equations were solved using Gausselimination
to determine quadrilateral doublet singularity strength distribution. Finally finite difference formula was
used to predict aerodynamic loads calculation.
