摘　　要：对纤维增强复合材料 (FRP)固体火箭发动机壳体的纤维缠绕 (FW)线型进行了简要地分析。鉴于封头曲面上 FW线型稳定性对于线型参数变化十分敏感 ,分析封头 FW线型时 ,本文仍从测地线方面来考虑。依此 ,两赤道圆处 FW角必须以左右封头几何尺寸及测地线 FW条件来确定。在对筒身段非测地线 FW可行性讨论中 ,提出了筒身段实现非测地线 FW的条件 ,同时推导出了筒身段非测地线The FW process is a prefect method of manufacturing FRP solid rocket engine shell and aerial press vessel.In this paper FW pattern of FRP solid rocket engine shell was analyzed in a nutshell.The stability of FW patterns on end head is very sensitive to changing of pattern parameter.Consequently,its FW pattern was based on geodesic track.The FW angles and on equators depend on the dimension of end head and the condition of geodesic FW.Generally speaking,the polar holes of rocket engine shell are disproportional.Therefore,the FW angles of the shell column are changeable.The feasibility of nongeodesic FW of the shell column was discussed in this paper.Furthermore,it expounded the indispensable condition between the length of shell column and the FW friction coefficient.At the same time,the general mathematic models of the movement control of nongeodesic FW were deduced.
