This study quantitatively analyzes how wingtip slots reduce induced drag, using a vulture-inspired bionic model of eight primary feathers. Induced drag was decomposed via wake-plane integration. Results show wingtip slots lower the induced angle of attack, mitigate vortex-induced flow deflection,. This verifies the method's applicability for evaluating and optimizing wingtip slot designs.
