Aerodynamic evaluation of a self-developed high-aspect-ratio flying wing standard model was conducted in a 2.4 m transonic blowdown wind tunnel. The tests quantified boundary layer transition effects, assessed measurement system precision, and characterized elastic deformations under critical test conditions. Longitudinal and lateral-directional aerodynamic performance analyses confirmed the model’s stability and suitability as a benchmark for high-aspect-ratio flying wing configurations. The derived aerodynamic database elucidates flow mechanisms, Reynolds number dependencies, and aeroelastic behaviors specific to such configurations. Additionally, the study validates advanced wind tunnel testing methodologies while supplying critical testdatasets for computational fluid dynamics (CFD) code verification. Findings underscore the model’s utility in advancing integrated testcomputational frameworks for next-generation aircraft development, particularly in addressing aerodynamic complexities of high-aspect-ratio flying wings.
