The effect of tail sweep angle to the aerodynamics and stability of a blended wing body aircraft (baseline V) / Mohamad Zulfazli Arief Abd Latif

Blended wing body (BWB) aircraft is theoretically designed based on the combination of conventional aircraft and flying wing which is likely to be the future concept of an aircraft. Some of the studies claim that BWB aircraft has higher lift to drag ratio compared to the conventional aircraft. However, by obtaining high lift to drag ratio only does not means that the aircraft has good longitudinal stability. Flight Technology and Test Centre (FTTC), Universiti Teknologi MARA Shah Alam began the research on BWB aircraft in 2005 and found problem related to the stability of the aircraft. Some ideas have been proposed to overcome the BWB‟s poor flight stability such as having large central elevator, installing canard, designing planform that mimics a bird, and installing long tail boom.
