structural analysis of fuselage with lattice structure

Project Title:Structural Analysis of Fuselage with Lattice Structure USING ANSYS.Prole! State!ent:The design of a fuselage structure for any aircraft is very essential. The fuselage structure for business jet aircraft carries stringers, frames, floor beam and outer skin. The fuselage structure for heavy passenger aircraft carries a wide numerous structural parts such as bulkheads, longerons, frames, stringers, flat plate, outer skin etc. Nowadays, stiffened shell structure was used in fuselage structure. The lattice structure is a complex design which carries an individual structural components of actual fuselage structure seen. In this project, the lattice structure was adapted to the aircraft instead of stiffened shell structure. The design of the lattice structure is carried out and the static structural analysis is carried out in AN! to find the stress and deformation due to the load.Project Intent: ". #nderstand the concept of fuselage $attice structure.%.
