A part of the UK research programme NEXUS ?Integrated Technologies for Future Wing Designs? has been to understand the opportunities and threats that new radical configurations pose. Unless such radical alternative options are tracked and understood the future benefit of any conventional technologies may be over estimated, especially if the radical option negates all of the proposed future benefits of a conventional design. The objective of the study has been to measure the impact on aircraft high speed performance of novel configurations. Two alternative novel configurations have been pursued which are the Blended Wing Body (BWB) and the Forward Swept Wing (FSW). The investigation included an initial aerodynamic assessment of BWB and FSW configurations to provide an initial insight of the potential benefits and technical risks of these novel configurations. This was then followed by sensitivity studies in which key wing parameters were varied. The aerodynamic data from these studies was then used to create trades data from which the impact on overall aircraft performance can be assessed. To enable these trade studies, rapid analysis and design methods were used, which were CFD methods coupled with the QinetiQ proprietary numerical design optimisation method CODAS. This paper will describe the analysis methods used, including results from validation studies. It will present results comparing the aerodynamic performance of various FSW and BWB configurations.
