Primary Adhesively Bonded Structure Technology (PABST). Phase 2. Detail Design

Abstract

This report covers the design, analysis, and trade studies conducted during Phase II, Detail Design of the Primary Adhesively Bonded Structure Technology (PABST) Program. During this Phase, drawings were made and released to Manufacturing for the construction of a 42 foot long test component simulating the forward fuselage of the C-15 airplane. The design concept, selected at the completion of Phase Ib-Preliminary Design consisted of wide spaced/close spaced internal longerons in the upper fuselage and external longerons in the lower (bilge area) fuselage. External loads were developed for both fatigue and ultimate loading conditions in conformance with the military specifications. The external shears and bending moments were matched to the Full Scale Demonstration Component test curves, adjusted for the actual test fixture loading points. Internal loads were generated and static, damage tolerance and fatigue analyses were performed on the Full Scale Demonstration Component. A spectra was developed based on a statistical analysis of information accumulated from Air Force operations and used for the fatigue and damage tolerance analyses.
