Fuselage Structural Analysis. Volume II. Center Fuselage and Engine Mounts

摘要

The structural analyses of the fuselage space frame, engine mounts and the propulsion system supports of the U. S. Army XV-5A Lift Fan Research Aircraft are presented. The space frame internal loads analysis was performed utilizing the IBM 704 computer program developed in conjunction with the XV-5A wing basic components analysis. Therefore, much of the report is made up of the deflections and internal member loads program output for the several loading conditions investigated. The space frame member critical loads are summarized and member allowables and margins of safety are presented. The propulsion system, including crossover ducts, tailpipe and forward engine support is reviewed and supporting structure analyzed for critical loading conditions. (Author)
