Abstract

In order to explore the characteristics of the launching flow field after launching a tube-shape weapon in a limited space, this paper uses ANSYS Fluent software to solve the launching flow field of a tube-shape weapon, and obtains the shock wave cloud map of the launching flow field, as well as the near and far Field pressure variation curve.The research shows that the launching flow field can be divided into three stages after launching in a limited space: the initial wave system formation stage, the shock wave reflection stage and the turbulence stage; the reflection wave formed by the collision of the shock wave and the wall will cause the pressure of the flow field to rise, The impact on the gunner's point pressure peak is higher, and the peak is 2.5 times that of the free shot, while the increase on the near wall point pressure peak is smaller.

Key words： limited space launch; tube-shape weapon; launching flow field
