Project Description

Blended wing body (BWB) aircraft designs are appealing due to their high lift-to-drag ratio. However, sizing constraints make these designs challenging as there is an excess of unused space in the trailing edge region. This project explores the viability of truncating the trailing edge region to reduce unused space and re-energizing the flow with a powered boundary condition to combat separation. Two dimensional truncated airfoils and three dimensional BWB models will be analyzed using USM3D computational fluid dynamic (CFD) code to assess the effect of the truncation and powered boundary condition. Ultimately, the addition of a powered boundary condition shows promising results for these designs, indicating further research into engine designs suitable for this concept is worthwhile.
