Brilliant video! An engineer's dream to fix problems simply with knowledge of flow physics and good judgement, rather than relying on sophisticated tools.

Wow. Really a good video. You have more actionable info in 8 minutes than most videos have in an hour. I very much appreciate all of it.

The over-surface NACA duct problem seems so evident in hindsight, yet must require experience to detect. Thanks a lot for sharing.

Great work! I now want to improve the aerodynamics of my vw scirocco 3 to reduce drag. I have 2 ideas 1) Use the factory air intakes located on the sides of the front bumper and make air outlet holes in the wheel fender 2) Make a grille in the skirt of the rear bumper so that the air from it goes directly into the low-pressure zone behind the car, thereby reducing it. If you can give me some advice, then I would be happy!

What an awesome video. Thank you. One thing I would like to know more about is relieving fender pressure.

I would be interested in a video on how analyse flow vis and cotton threads please ! Very interesting video

very informative video. goes to show that all the fancy software and analysis won't do you any good without fundamental knowledge and the ability to test empirically and improve based on that. I'm not in the full time workforce yet but that's definitely something my school's Formula SAE team could stand to learn from...

What an amazing chanel you've created! Bravo! 👏 So much knowledge and useful information is very hard to find, and to be so understandable and dense. You're an amazing engineer! This is so interesting, to me at least, I can't believe I didn't find your videos earlier.

Does the effect of gravity on the flow-vis ever cause issues? Or are the aero effects always much more significant?

@BSport320

2 жыл бұрын

I mean once you sprayed it on the car, it should really start driving, overwise it will dry while the flow viz is running down. Same goes for hot surfaces (bonnet etc.) It will be dry before the car starts driving. But as soon as you are driving the flow effect is more significant than gravity.

Thanks for insightful video’s!! Many engineers dream of being in the hothouse of intense pressure of F1… you had (it seems, a relatively short) time in F1, and then left. So whats more challenging, being a high-focus specialised F1 engineer or being a freelance engineer with a high diversity of challenges & opportunities? Also, would you go back to F1 (or LMH/LMDh) if approached by a factory?

@BSport320

I've been in F1 for 3 years, which is normal looking at my work mates. 4-5 years is regarded as a long time in F1:) Anyway, I left because I wanted to start my own business and enjoy the freedom and variety of projects now more than being specialized on a particular area. Never say never but currently I am pretty happy being self-employed.

Really enjoyed this video, good combination between theoretical knowledge and understandable practical applications. Why kind of engine were you guys running, why not the NA V8?

Thanks! The NA V8 needed 3 times more fuel per lap which resulted in too many pit stops. The better choice for long endurance races was the V6 TDI.

Great Stuff. A question on the NACA ducts in the floor....you said they had a "step" which was preventing them working efficiently.....how big was this step? The pic you showed had them mounted externally to the floor, with the "lip" on the outside, so is that step (i.e. the 2-3mm or whatever the thickness of the plastic is) too small to be a problem?

@BSport320

2 жыл бұрын

The step was 2mm and separated the flow. We could see that with flow viz and at the diff temperatures. After removing the step in front of them, the NACA ducts worked fine.

Cool. What was the difference in lap time? 😬

@BSport320

2 жыл бұрын

That's not easy to say because the video summarizes one year of updates and the conditions at the Nurburgring are different every time. But with aero updates + some software updates for the engine, we were able to reduce lap times from 10:10s to around 9:50s (25km VLN track)

question: are the old open top CanAm cars way better aero-wize? less frontal area, hatchback shapes are better then coupe shapes. i know their are easier to design and cheaper due to no doors or roof. thanks

Seems a choice of compromise: open cockpit so less drag, more flow to the back, but less surface to guide it. Even if the former seems to me the less relevant. Viceversa for every point for the closed one

As a small team we couldn’t just simply change tyre size on an all-wheel-drive car. We were pretty happy with the mechanical grip and the static downforce of the nose heavy Audi was good anyway. But for more performance at faster corners it makes sense to have them. We worked on front diffusers lateron.
