常规的气动设计中将弹箭视为刚体,不考虑弹性变形对气动特性的影响。同时,为了抑制弹性变形的不利影响,只能增加结构刚度,在外形和重量上付出了沉重代价。此外,由结构弹性与气动力的相互耦合而引发的气动弹性效应,对飞行器的结构
Conventional pneumatic design sees a projectile as a rigid body, irrespective of the effect of elastic deformation on the aerodynamic characteristics. At the same time, in order to restrain the detrimental effects of elastic deformation, only the rigidity of the structure can be increased, which has paid a heavy price in appearance and weight. In addition, the aeroelastic effect caused by the mutual coupling of structure elasticity and aerodynamic force, the structure of the aircraft
