Boundary layer, skin friction, and boattail pressure measurements from the YF-12 airplane at Mach numbers up to 3 [PDF]

, 1978
In-flight measurements of boundary layer and skin friction data were made on YF-12 airplanes for Mach numbers between 2.0 and 3.0. Boattail pressures were also obtained for Mach numbers between 0.7 and 3.0 with Reynolds numbers up to four hundred million.

Why Drag? Observations on drag performance in times of drag popularity

Documenta, 2019
Simon Baetens is een student Drama aan het KASK, waar hij momenteel zijn master afwerkt. In deze artistieke bijdrage, werpt hij een blik op theoretische hoek op een andere artistieke praktijk van hem als dragperformer. Aan de hand van een visuele en tekstuele collage, maakt hij een kritische reflectie over drag in connectie tot zijn eigen werk binnen ...
