| Abstract: | At the present, spatial lifting systems are usually calculated numerically using linear approximation. However, the practical application of such systems at moderate and large angles of incidence requires new approaches that allow for various nonlinear effects such as large disturbances, flow separation, and jumps in entropy across shock waves. The existing investigations 3, 4] generally cover only simple systems (bodies of revolution, wings, and so on). Here, a numerical method is proposed for investigating supersonic flows past complicated spatial systems. The method extends and continues the well-known methods widely used to solve analogous problems in subsonic aerodynamics 5, 6]. Some examples of the computation of the aerodynamic parameters for flows past wings and spatial lifting systems are also given.Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No. 3, pp. 142–148, May–June, 1993. |
