Studies dealing with tensioning and packaging, reducing stress risers, fabrication of 7-in. pressure vessels, 18-in. rocket cases and bending tests are reported. The 7-in.-diam pressure vessel and the analytical and experimental methods used to derive the end dome configuration are discussed. Comparison of stress values obtained for tape and roving from identical designs were of the same order of magnitude. The tape material compacted better t an r ving in both the cylindrical and end dome regions because of the more uniform control of width and thickness of the tape. A balanced designed isotensoid geodesically wrapped pressure vessel 12.5 degree longitudinal wrap angle is weakest in the longitudinal winding at the point of tangency. The design concept for off-center port reinforcements is presente . a method utilizing a filament wound cylinder which can have a pure bending moment applied without special machining is discussed.
