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...

Development, Model Generation and Analysis of a Flying V Structure Concept

The Flying V, a concept aircraft configuration, has been proposed by Airbus and TU Berlin. The initial indications of potential improvements in performance over conventional aircraft gave rise to a continuation of the research. For this, the mass characteristics of the configuration must be explored. <br/><br/>A primary structure concept is...

Conceptual Design of Blended Wing Body Airliners Within a Semi-automated Design Framework

Blended wing body aircraft represent a paradigm shift in jet transport aircraft design. Stepping away from the conventional tube-and-wing philosophy, they promise benefits over existing or future conventional aircraft. The most significant challenge with the concept is the increased coupling between aircraft design disciplines that has...

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...

Rudder Incorporated Winglet Design for Blended Wing Body Aircraft

Concern about the environmental footprint of aviation has re-sparked the interest in unconventional configurations, such as the blended wing body aircraft, BWB. While most research studies recognize the potential of the hybrid-body, they also list a number of challenges. Amongst these challenges is the need for adequate lateral-directional...

Effectiveness of Thrust Vectoring Control for Longitudinal Trim of a Blended Wing Body Aircraft

The application of thrust vectoring on civil transport aircraft has only been studied by a few individuals.

Blended Wing Body configuration is a novel aircraft concept. Due to the...

A hybrid method for the interior and exterior design of blended-wing-body cabins

Considering the fact that all large commercial aircraft have not changed significantly in their tube–and–wing shape during the past few decades, one would suggest that a completely different configuration is necessary to facilitate a new leap forward in aircraft performance. The blended–wing–body is potentially such an alternative configuration....
