To establish a unified aerodynamic design and optimization framework for morphing Blended-Wing-Body UAVs.
Integrated parametric CAD modeling and Computational Fluid Dynamics (CFD)
Surrogate-based optimization using Response Surface Methodology (RSM)
Sensitivity analysis of geometric parameters including sweep, taper, and twist
Achieved a 56% improvement in lift-to-drag ratio relative to conventional UAVs
Validated the optimization framework across multiple Mach numbers (0.2, 0.4, and 0.8)
Established that geometric twist and taper dominate lift variations at low Mach numbers

Kang et al. (2026) studied this question.
