So some answers about the use of 'AI' (or let's say ML/DL) for aero development :
At least 6 F1 teams are using it (probably all of them by now, maybe with a different supplier)
Biggest advantages are : instant result as opposed to hours or days, and considered as post-processing so no limits on number of predictions as opposed to CFD / wind-tunnel runs
Also, makes collaboration between engineering teams (aero, design, structure) much more easy. Instant results means no need to wait for the next meeting, waiting for the results
Some explanations on inputs : parameters vs geometries. ML vs DL
Training the model. Quality and distribution VS quantity. Teams tend to use the data they already have available and deal with it despite the greater uncertainty
Dealing with uncertainties with a Traffic Light System
Other uses : crash test, acoustics, probably strategies etc.
Just one more tool for the engineers, still people to take the decision after the predictions are done
