Regarding annular wings #2... (Season 1, Episode 4)

High Quality RC Electronics Here: http://www.r2hobbies.com/eng/categories.php?PARTNER=experimentalrc

This episode I will be going over the fluid dynamics of annular wings by doing smoke wind tunnel testing. Visit my website www.rcexperimental.com and subscribe, because more videos are coming soon. I have also been working on plans for a 3D annular wing foamy and free plans will be avaliable on my website as soon as possible.

Damn!! Is she a girl!! 'Cause brains are sexy!! She talks kinda slow but I love airplanes & I like her!!

@Zorayda85 Guy actually. Thanks for the self esteem booster. :) Don't worry, my voice has deepened in the past two years and I have my hair cut shorter now. Hope you find someone though, you sound lonely.

interesting, but was that a piece of cotton candy in the tunnel?

[RCexperimental]

@Ignantredneck Haha probably just some hot glue strings. :)

Very nice to see young scientists at work! One positive type of constructive critique for you: the smoke is "pushed" into your chamber (not "sucked") due to the lower pressure formed inside the box from the vacuum cleaner. Fluids/gas moves from high pressure to low pressure. You should change the terminology used in this respect going forwad. Congrats on the video.

[RCexperimental]

Ya, that makes sense, but then is anything really "sucked"

[RCFindsen]

try some kf's that would be cool

[RCFindsen]

fix ur audio

[jeetendrag10acc2]

put a pen laser through a fresnel lens (the kind you get from changing pics rulers and on candy boxes) and you will get a fan beam laser. from this you can see your vortices clearly by cutting through the smoke with a fan beam.

What a nerd

Good to have people like this in the world.

Good for you man

Fantastic work! The wing analyses were very well done. Were the wings cut from foam? Is there a system for adjusting AOA while the wind tunnel is running?

Just one tip: the singular form of "vortices" is vortex.

Keep up the good work!
