      Application of 3D least squares meshless method is studied in complex supersonic flow field in present paper.Discrete points approximating orthogonal uniform distribution are generated aiming at the calculated characteristics of least squares meshless method.And the flow field of B1AC2R generic missile in supersonic is computed by least squares method.Viscosity is not considered.Axial/Normal force and pitching moment coefficients of missile are analyzed at different angles of attack respectively.The simulation results agree well with the experiment results.All these results demonstrate that the proposed meshless method can be applied to simulate the complex flow problems accurately and practicability.
