#f1 #formula1 #aerodynamics Improving F1 Aerodynamics using AirShaper CFD simulations - The Voyager-AirShaper F1 challenge For other aero updates: - Part 2: - Part 3: - Part 4: UPDATE: we found a mistake in the simulation - the increase in downforce was 44% and not 64% - check the next video (on aero update 2) to learn more! Simulations: Original car: Aero Package 1: In this video, we present the first set of aero updates to the Voyager-AirShaper F1 car. The redesign has been based on: - Input from the talented people who contributed to the AirShaper Reddit channel - Input from AirShaper (supported by aerodynamic shape optimization) We've focused on a number of areas: FRONT WING - We implemented the design of Busor to have a more updated design - The spacing between the wing elements was increased to avoid mesh bridging - The sideplates were pushed inward at the front to reduce flow separation The downforce on the front wing improved dramatically, with low pressure zones on the suction side being much more pronounced, now extending to the second and partially the third wing element. STRAKES - The thickness of the straks was reduced to avoind local flow separation - The "inlet angle" of the strakes was increased, to point more inward. - The "outlet angle" of the straks was increased as well, to be outward instead of parallel to the driving direction of the car. The result is less flow separation at the inleg and stronger vortices further downstream, resulting in a lower pressure and thus more pronounced suction effect across the majority of the underfloor. BIB The bib (sort of a scoop around the central part of the underfloor) was added, grabbing some extra downforce (as the pressure on top of it pushes it downward - even though some of this is cancelled out as this higher pressure also acts on the surface above the BIB). OTHER Other small changes include updated barge boards and a different nose angle. A MASSIVE THANKS TO ALL OF THOSE WHO CONTRIBUTED TO THIS AERO PACKAGE And a special thanks to the guys at Voyager for implementing all of the community suggestions Links General: /// F1 Challenge: Reddit: Contact: ----------------------------------------------------------------------------------------------------------- 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!
