By the semi-inverse method proposed by He, a variational principle is established for steady flow over a thin, symmetric, non-lifting aerofoil. The nonlinear, small-disturbance, velocity-potential equation is obtained by minimizing the obtained functional, and all boundary conditions are converted into natural boundary conditions, resulting in much convenience when incorporating the finite element method.
