For more than two weeks I've been trying to understand the principles teached in this video in order to understand the difference between vortex generators and wing fences. I started with books, then articles on the internet and finally I found this amazing class. Thank you so much to all bold method team, you are awesome!!!
Guys your explanation about how shockwaves for above wing don’t really make a lot of sense. Your notion that the airflow moves from the leading edge to the trailing edge … but it gets backed up because it’s moving too fast it .., doesn’t make a lot of sense. Look at the explanation offered by the military explanation of shockwave formation. Their explanation is completely opposite of yours. They explained that the pressure waves are building up from the trailing edge and they get blocked up as they try to move forward. That seems a lot more intuitive, doesn’t it? Look at the 2:50 mark on this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ugPJYJ-BKkU.html
Excellent presentation, truly enjoyed. To be more precise, M# = TAS/LSS. LSS meaning the local speed of sound. LSS (in KT) = 38.94 V Absolute Temperature (K) LSS (in KT) = 38.94 V°C + 273. (It’s not a V it’s a square root, can’t seem to replicate). Keep up the nice work.
I think spanwise flow should be showed on leading edge of the wing, that would show in intuition how it works. (and arrows from fuselage should be first: relative wind, spanwise flow on leading edge and chord line of wing connecting tips of spanwise flow and relative wind)
Hi so from my understanding, is the Blodmethod logo of a bow wave? And also what's the name of that symphony at the beginning...I love listening to it rite before learning from u guys at boldmethod...I swear if I had it as a ring tone I'd always have to call back once it's done lol😂
The illustration showing the shockwave over the wing is incorrect. A shockwave is formed at 1.0 not 1.05 or anything above 1.0, but right at 1.0. Other than that, it is a very good video.
The shockwave is formed when the airflow slows down to below M 1.0, not speeds up to 1.0 This presentation is correct, as it's shown in between 1.05 and .95, showing the formation just as it falls under 1.0
