Abstract
This paper was presented at the 18th National Conference of the Society of Aeronautical Weight Engineers at Atlanta, Georgia, May 18-21, 1959. It addresses the problems associated with efficient design of pressurized skin-ring-stringer aircraft fuselage structure. A method of analysis for defining the stresses associated with this type of design is discussed. Extension of this method is made to provide a solution of fatigue and related problems, particularly that of crack propagation and fail-safe design. A parametric evaluation approach is evolved for use in weight estimation and design optimization studies.
