箭体上的凸起物对火箭气动特性的影响

综合大量实验研究结果,本文给出了火箭箭体上的环形凸起物和纵向凸起物对火箭气动特性的影响。其中最主要的是改变滚转力矩的大小和方向。而这正是姿态控制系统设计的重要依据之一。因此,给出凸起物的设计原则,对火箭气动设计有实际意义。

AERODYNAMIC CHARACTERISTICS THE ILNFLUENCE OF PROTUDERANCES OF MISSILE BODY ON MISSILE

Based on a number of experimental results, this paper sums up the influence of annular and longitudinal protuberances of missile body on missile aerodynamic characteristics. The most important influence is changing the level and direction of the rolling moment, which constitute one of the basis for attitude control system design. Therefore, the present provided the design principle of protuberances that has practical significance for the missile aerodynamic design.
