| 内容記述 | A numerical method for computing inviscid transonic flow around an arbitrary aircraft configuration is described in this paper. The basic formula consists of simultaneous equations for variables of velocity potential and Mach number. This formula is a permutation of the full potential equation. The simultaneous equations are solved numerically, satisfying given boundary conditions. The shock wave is captured as a discontinuous surface where the flow conditions satisfy the shock wave relationship. The calculation flow field is a rectangular box field. Grid points and boundary points are generated in Cartesian coordinates. The grid points are equidistant but their intervals can be varied with the location. External forms of the aircraft and vortex sheets are shaped from numerous small triangular planes. The majority of the boundary points are on these external forms. The basic formula is expressed as difference equations using the grid points and the boundary points. The difference equations are solved in the numerical procedure. Several calculated results of this method are compared with the experimental and other numerical results. | |||||||||
