Abstract: As control force source,the solid propellant gas generator was used to exert lateral force for the end control and the turn of vertical launching of missiles. Missiles with lateral jet as control force had complicated flow field. According to the theory of dissipation analogy, compact upwind TVD scheme with high precision was made out.Two dimensional axial symmetry numerical simulation to the lateral jet flow field was conducted.The research show that if the coming stream is supersonic and the lateral jet is sonic, the force of the lateral jet will reach the maximum value when the jet out angle is an acute angle.
