Analytical Investigation of Medium STOL Transport Structural Concepts. Volume II5 Isograd Fuselage Study.
Abstract
Results of a study program to evaluate application of the isogrid structure concept to a medium STOL transport aircraft are presented. Isogrid is an integrally stiffened panel concept incorporating a triangular arrangement of the stiffening material which has been used successfully on space vehicle structure. The fuselage shell structure of the projected C-15 production airplane is used as the study (and baseline component. The isogrid concept is evaluated for structural concepts are based on a common set of requirements for ultimate strength, fatigue, and damage tolerance. Because of generally lower stress levels and a general absence of rivet and bolt holes in basis isogrid structure, fatigue and damage tolerance are of reduced criticality relative to baseline structure.
