N2 - The aerodynamic design benefits and configuration integration challenges of blended wing body (BWB) configurations over traditional tube-and-wing (TAW) designs have been thoroughly studied over the years. Research has shown that an intermediate approach, the lifting-centerbody (LCB) configuration is optimal for regional and short-haul passenger aircraft, providing a significant aerodynamic benefit while reducing the integration complexity. In this paper, we characterize the geometry and configuration aerodynamics of LCB aircraft across a range of wing-body blending. We use a variety of aerodynamic analysis methods to characterize the surface pressure and lift distributions and determine the sensitivity of various performance parameters to the degree of blending, and inform configuration design guidelines through these studies for aerodynamic design of LCB aircraft. We postulate that spanload optimization strategies can provide significant reduction in induced drag for an LCB configuration over tube-and-wing configurations, and understanding the chordwise effects can further play an important role in the performance of these designs.
