Knowledge-Based Engineering Approach to the Finite Element Analysis of Fuselage Structures

In this work a Knowledge-Based Engineering approach is presented for validating the results of a semi-analytical weight estimation method used for the conceptual design of conventional and oval fuselages structures. The validation of these results is carried out by comparing the structural component's line loads as calculated by the semi...

Semi-Analytical Weight Estimation Method for Fuselages with Oval Cross-Section

This paper presents a semi-analytical method for the weight estimation of fuselages with an oval cross-section, applied to blended wing body aircraft. The weight estimation of the fuselage primary structure is based on a structural analysis of two-dimensional crosssections and it is completed by a set of empirical relations for the weight...
