Metamodels for Composite Lattice Fuselage Design

Design and Analysis of a Composite Fuselage

The present study presents a new methodology developed for an analytical model of a composite fuselage. It also presents finite element analyses of a simplified model and comparisons with more complete models. These comparisons show that there is a very good correlation between both models for the cases studied. Therefore, the applicabilty of the proposed procedure was demonstrated. Based on fi...

Topology and Parametric Optimization of a Lattice Composite Fuselage Structure

Conventional commercial aircraft fuselages use all-aluminium semi-monocoque structures where the skin carries the external loads, the internal fuselage pressurization and is strengthen using frames and stringers. Environmental and economic issues force aircraft designers to minimize weight and costs to keep air transport competitive and safe. But as metal designs have reached a high degree of p...

High Fidelity Failure Analysis for A Composite Fuselage Section

A high fidelity delamination failure analysis was developed by combining a local failure analysis with a global fullscale finite element structural analysis to address strength and delamination failure in a single package. The methodology was demonstrated through a local threedimensional pull-off failure analysis and a geometrically nonlinear structural analysis of a five-foot composite helicop...

Thermal Analysis of Composite Fuselage Skin for Tool Correction

Realization of laminated fiber reinforced composite structures through autoclave process is quite challenging. This is due to the complex geometries of the composite structure and also due to the bending and stretching coupling introduced by stacking of plies of different orientations. In the curing process due to the different coefficients of thermal expansion of the composite component and th...
