AIRBUS Talks - Aircraft Design Tools

For more on AIRBUS: - Part 1 - Aviation challenges: https://youtu.be/IgowvQZ3JtE - Part 3 - America's Cup Aerodynamics (1/2): https://youtu.be/ZcD9iA9DPrI - Part 4 - America's Cup Aerodynamics (2/2): https://youtu.be/AdGuENBuZ-Y In this second video in our series 'AIRBUS talks' we dive into the different methods that are used to design a modern airplane: - CFD (computational fluid dynamics): aerodynamic simulations running on high-performance computers - Wind tunnel testing: using scaled models inside a wind tunnel to analyze multiple set points - Flight testing: flying the real airplane to map its behaviour, performing reject take-off scenario's, stall angle detection, ... AIRBUS gives us insights into the benefits of these methods: - CFD: it's possible to simulate the real Reynolds number - the real speed & size of the airplane - Wind tunnel testing: you can analyze multiple setpoints over a single campaign - Flight testing: the one & only end evaluation Most of the efforts are focused on cruise flight, as this represents 90% of the operating regime of the plane. We also zoom in on the challenges of keeping the Reynolds number the same. AIRBUS even goes as far as working with different gases at low temperature & pressure to get the same Reynolds number as the real aircraft! They've performed tests at DNW (German-Dutch Wind tunnels), ETW (European Transonic Wind Tunnel), DLR (Deutsche Luft & Raumfahrt) and more. Coming up next: How AIRBUS was and is involved in the America's Cup! ----------------------------------------------------------------------------------------------------------- The AirShaper videos cover the basics of aerodynamics (aerodynamic drag, drag & lift coefficients, boundary layer theory, flow separation, reynolds number...), simulation aspects (computational fluid dynamics, CFD meshing, ...) and aerodynamic testing (wind tunnel testing, flow visualization, ...). We then use those basics to explain the aerodynamics of (race) cars (aerodynamic efficiency of electric vehicles, aerodynamic drag, downforce, aero maps, formula one aerodynamics, ...), drones and airplanes (propellers, airfoils, electric aviation, eVTOLS, ...), motorcycles (wind buffeting, motogp aerodynamics, ...) and more!
