Peer-reviewed STOKE!

very interesting indeed. i love this sort of stuff.
hooray for physics and the way of the world.

that pass on the left bit is definetly something to remember. 

The percentage of overall drag breakdown is suprising, wouldn't have guessed that your helmet is almost a third, or your board being as much as it is?

makes sense though, but yeah the board creates far more drag than you think it would aye.

Great post! That was a good read.

I'd say it is such a high proportion because it would generate a very turbulent region underneath. Front spoilers/skirts on cars are there to deflect airflow to prevent it going under the chassis (as well as create downforce) to reduce drag.

...spoilers for your skateboard?

Ultimate downforce and grip.

When you look at street lugers, they certainly design their luges with airflow in mind. Why should it be any different with skateboards?

Rad as, I found this one on the fish just this week. I put a discussion in the members lounge with reference to it. The legs making up a large proportion of the drag. I had been wondering how that would be effected by the position of the back knee. Right Behind the front knee V's mid calf like the dude In the study v's right down low near the Achilles tendon ofthe front leg????

how i wish i was smart enough to understand this :(

Its definetly not new, I think these are from mid 2009

 

obligatory pictures

Maybe Chaput was onto something?

It's really interesting, hopefully they do more modelling with a variety of positions and tucks, as well as different speeds.

Alex, our body and the position we ride in makes the majority of the differance when it comes to aerodynamics. Your body creates more disturbance as far as airflow is concerned, compared to ours. The other factor is the luges are alot bigger in area than a skateboard, which means any aerodynamic "component" we add to the luge design will have a greater effect, as compared to a small longboard (area). You could try putting "wheel spats" on your wheels, see how it goes.
