Abstract

Aerodynamic optimization of airfoils is fundamental for aircraft performance, with NACA2412 and NACA0012 serving as benchmark prog actionable insights for airfoil design under variable operational environments. Files for commercial wings and helicopter rotors respectively due to their contrasting pressure recovery characteristics. However, contemporary research exhibits critical gaps in transitional Reynolds number (Re) regimes (1×10⁶< Re<3×10⁶), where conflicting reports exist regarding laminar-turbulent transition patterns. Compounding this, dynamic stall prediction discrepancies exceeding 22% persist across numerical models at Re=2x106, undermining airfoil selection for variable-speed aircraft. This investigation integrates improved delayed detached eddy simulation with wind tunnel measurements using oil-film interferometry (Re=1.2×10⁶–5.8×10⁶). These results reconcile scale effects in transitional flows through quantified vortex-shear layer interactions, addressing contradictions in separation criteria. The derived Re-CLmax correlation (R²=0.94) enables adaptive wing optimization for UAVs operating across maritime altitude conditions. This study bridges the gap between theoretical models and practical engineering challenges, offering actionable insights for airfoil design under variable operational environments.
