Some insects actually SWIM through the air by using drag as the vertical force instead of lift. But how? That's what we're covering in this podcast episode.Interested in plane aerodynamics?

Fixed-wing aircraft aren’t supposed to turn like this.So how do birds pull off insanely tight turns—and can planes do the same?In this video, we break down a recent aerodynamics paper that shows how bird-inspired morphing wings and tails dramatically increase turning performance in fixed-wing aircraft. Using wind-tunnel experiments and real flight data, the researchers reveal why changing shape matters more than just adding control authority.We’ll cover:Why conventional planes struggle to turn tightlyHow birds use wing morphing + tail control to stay agileWhat the experiments actually measured (and what surprised the researchers)What this means for drones, UAVs, and future aircraft designsIf you’re into aerodynamics, CFD, flight mechanics, drones, or biomimicry, this one’s for you.Learn CFD / Aerodynamics✅ OpenFOAM Courses: https://premieraerodynamics.com/Courses/✅ Automotive Aerodynamics Course: https://premieraerodynamics.com/Automotive-Aerodynamics/✅ RC Airplane Design & Build Course: https://premieraerodynamics.com/RC-Airplane-Course/Work with me🚗 Car CFD Simulation Commissions: https://premieraerodynamics.com/Simulate-Your-Own-Car/Community💬 Free Discord (CFD + aero discussion): https://discord.gg/QajxVpmYMQ📄 Paper link (open access):https://link.springer.com/article/10.1038/s44172-022-00035-2?fromPaywallRec=false, Sharp turning maneuvers with avian-inspired wing and tail morphing, https://doi.org/10.1038/s44172-022-00035-2, licensed under: http://creativecommons.org/licenses/by/4.0

Asymmetric Vortex Breakdown Over A Triple Delta Wing | Mach 0.85 Sideslip AerodynamicsThis episode explains asymmetric vortex breakdown on a triple-delta wing at transonic speed (Mach 0.85) with a 5° sideslip angle. Using results from a high-fidelity CFD study (including pressure coefficient maps and vortex visualizations), we show how sideslip creates windward/leeward differences, how vortex merging changes with angle of attack, and why breakdown can happen earlier on one wing — with real implications for stability and pitching/rolling moments.📄 Research paper: https://link.springer.com/article/10.1007/s13272-022-00571-9?fromPaywallRec=false, Investigation of transonic aerodynamics on a triple-delta wing in side slip conditions, licensed under creative commons: https://creativecommons.org/licenses/by/4.0/Learn CFD / AerodynamicsOpenFOAM Courses: https://premieraerodynamics.com/Courses/Automotive Aerodynamics Course: https://premieraerodynamics.com/Automotive-Aerodynamics/RC Airplane Design & Build Course: https://premieraerodynamics.com/RC-Airplane-Course/Work with me🚗 Car CFD Simulation Commissions: https://premieraerodynamics.com/Simulate-Your-Own-Car/Community💬 Free Discord (CFD + aero discussion): https://discord.gg/QajxVpmYMQ

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

Motorcycle aerodynamics looks simple — until you actually try to model it.At racing speeds, the airflow around a motorcycle is highly unsteady, asymmetric, and dominated by the rider, not the bike. Small changes in posture can completely restructure the wake, creating a problem that is closer to controlled chaos than clean textbook aerodynamics.In this episode, we break down why motorcycle aerodynamics is so hard, using insights from CFD, turbulence modeling, and published research. We’ll look at:Why the rider creates so much of the dragHow flow separates around the helmet and shouldersWhat the wake actually looks like at high speedHow models like DES, SAS, and k-ω SST are used to capture unsteady flowWhether you’re an engineer, racer, or just curious about why motorcycles behave the way they do at speed, this episode will give you a deeper intuition for the problem.Motorcycle vs rider drag contributionFlow separation and wake structureTurbulence, vortices, and unsteady aerodynamicsScale-Adaptive Simulation (SAS) vs Detached Eddy Simulation (DES)Why motorcycles don’t behave like cars in the wind tunnelCOURSES:Automotive Aerodynamics Course: https://premieraerodynamics.com/Automotive-Aerodynamics/UAV Design And Build Course: https://premieraerodynamics.com/RC-Airplane-Course/Want to simulate your VERY OWN car?
