Why Birds Almost Lose Control When Landing

Birds don’t “flare and gently land” the way we usually imagine. Many species ride the stall edge on purpose—trading stability for control right at touchdown.In this episode, we break down a recent aerodynamics paper on bird perching/landing near stall, what the data actually shows, and how it maps onto concepts you already know: lift breakdown, unsteady separation, pitch control, and energy management.What you’ll learn:Why birds approach the perch at very high angles of attackHow they stay controllable near stall (and when they don’t)What “controlled stall” means in real aerodynamic termsHow this compares to aircraft physicsWhy perching is an extreme case of unsteady aerodynamicsIf you like deep dives on new aerodynamics research + car aero simulations, subscribe for weekly episodes.🎓 Learn more (if you want to go deeper)🔹 RC Airplane Design CoursePropellers, airfoils, performance trade-offs, and aircraft-level design👉 https://premieraerodynamics.com/RC-Airplane-Course/🔹 Learn OpenFOAM for Aerodynamics & CFDFrom meshing and validation to interpreting results correctly👉 https://premieraerodynamics.com/Courses/🔹 Automotive Aerodynamics CourseDrag, downforce, cooling flow, wakes, and real CFD case studies👉 https://premieraerodynamics.com/Automotive-Aerodynamics/🚗 Commissioned CFD simulationsIf you want answers without learning CFD, I also do commissioned aerodynamic simulations for real vehicles.If you’ve ever wondered what the airflow around your car is actually doing, you can find details here:👉 https://premieraerodynamics.com/Simulate-Your-Own-Car/📚 Paper discussedAgile perching maneuvers in birds and morphing-wing drone, https://link.springer.com/article/10.1038/s41467-024-52369-4?fromPaywallRec=false, licensed under: https://creativecommons.org/licenses/by/4.0/#Aerodynamics #FluidDynamics #BirdFlight #Stall #Aviation #CFD #WindTunnel #NatureCommunications
