摘要
提出了一种全新的机动弹头气动舵面布局概念,将气动舵面与一个可旋转的圆盘基座紧密固连,通过圆盘基座的整体旋转实现舵面的偏转。这种设计完全避免了舵轴附近的缝隙加热问题,因为根本就没有舵轴;舵面与旋转圆盘基座固化为一体,也直接导致了连接强度和刚度的极大提高。气动特性和飞行性能计算评估结果表明,这种新的机动弹头气动舵面布局理念是可行的。
In this paper, a new concept of maneuverable warhead aerodynamic configuration with knoblike control surfaces is proposed, each control surface is tightly joined to a rotatable round plate, and the deflection of control surface can be achieved by means of the round plate＇s rotation. This new concept could avoid the gap areoheating problem between the control surface and the body which always presents in traditional maneuverable warhead configuration. The computed results of its aerodynamic characteristics and flight performance show that this new configuration concept of control surface for maneuverable warhead is feasible.
