ABSTRACT:
A method for filament winding a pressure vessel having at both end domes thereof holes of different diameters and preferably used for a high pressure combustor of a rocket engine. The present method comprises first and second winding processes. In the first process, the first mandrel on which the winding band is wound is provided with a jig which makes the outer diameters of the opposite bosses of the mandrel be equal to each other and is removed after hardening process. In the second process, the winding band is again wound on the second mandrel comprising a first body obtained from the first process and provided with a jig which makes the outer diameters of the opposite bosses of the second mandrel be equal to each other and is removed after hardening process. In result, the winding band is always wound on the mandrel along straight winding passages in the two winding processes because the outer diameters of the opposite bosses of each mandrel are equal to each other, thereby causing the pressure vessel manufactured by the present method to have a good structural strength efficiently enduring high pressure.
