Improving MotoGP aerodynamics using CFD simulations - The Dotto Creations - AirShaper MotoGP Challenge - Aero Update 2

General information: https://airshaper.com/motogp-aerodynamics-challenge

Aero update 2 (with wings on the front wheel): https://app.airshaper.com/projects/dotto-creations-airshaper-motogp-challenge-aero-update-2-lower-wings-over-fender

For the second aero update, we had modified:
- the front fairing / wind screen: we aimed for a more horizontal exit angle by making the front face steeper
- Changed the position of the lower wings to the front suspension
- Deleted the rear wing

Results:
- Fender: the wake structure has improved around the fender & rider (more horizontal), but the wake is too wide now, causing extra drag.
- Front mud guard: better flow attachment here, but the bolt which is sticking out is creating a lot of drag
- Wings: these help a lot to clean up & direct the airflow around the legs & arms of the rider.

Drag & downforce values can still be improved further, so we'll continue work for aero update 3!

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!

The Chery aero concept claims a drag coefficient of just 0.168, which is significantly lower than the values of Tesla, Lucid which hover around 0.20.

This is still a concept car, so it remains to be seen how it performs once it goes into production.
