Design for bird strike crashworthiness using a building block approach applied to the Flying-V aircraft

The Flying-V aircraft concept promises better fuel-burn performance over conventional tube-and-wing configurations, integrating the passenger cabin and cargo volume into the lifting surface. However, the wing-fuselage and cockpit windows of the Flying-V are exposed to the flight direction, posing a new challenge to the design and...

Assessing the climate impact of the AHEAD multi-fuel blended wing body

Air traffic is important to our society and guarantees mobility especially for long distances. Air traffic is also contributing to climate warming via emissions of CO2 and various non-CO2 effects, such as contrail-cirrus or increase in ozone concentrations. Here we investigate the climate impact of a future aircraft design, a multi fuel blended...

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...

Conformable Pressurized Structures: Design and Analysis

There are many applications where volume needs to be pressurised within a geometrical space for which conventional pressure vessels do not provide suitable solutions. Applications are for example found in pressure cabins for Blended Wing Body Aircraft and conformable pressure vessels for an incompressible medium that has to be stored in a...

Optimization of Blended Wing Body Aircraft by Automatic CFD Driven Design Tool

Blended Wing Body (BWB) Aircraft has aroused a considerable interest as a potential candidate for future large subsonic transport air-vehicles. In this paper, we present the results of one and multi-point multi-constrained optimization of a BWB configuration for minimum total drag. The optimization technique is based on Genetic Algorithms and is...
