Aerodynamic Characteristics and Flow Field Investigations of an Optimal Hollow Projectile

摘要：

　　Computational fluid dynamics(CFD)is applied to simulate a 2-D hollow projectile with optimal geometry at different Mach numbers and different angles of attack to investigate the shock wave structures and drag characteristics.Different types of shock waves appear in the front of projectile with the variation of Mach numbers,and the structures of flow fields and total drag coefficients have obvious differences.Moreover,the influences of the viscous effects on the pressure distribution of projectile surface and total drag are analyzed.Finally,the variations of drag and lift coefficients with different Mach numbers and different angles of attack are discussed in detail.
