Paulipod 0 #26 November 10, 2004 Hmm... would a re-circulating tunnel go into the sucker or blower category I wonder... As the flow is pulled then pushed Either way, based on all the debate within this thread I have decided to rename our facility to the Bedford Joy Pipe.

Bodyflight.Net 0 #27 November 10, 2004 Paul, ya know I luv ya by now right? I don't see anywhere where the new Bedford Joy Pipe actually 'pushes' unless I'm missing something. HOWEVER, your recirculating tunnel, with it's single fan/prop above orientation is much more efficient than the 'other' competitors sucking design, but is still a sucker The single fan/prop above recirculating design creates an environment friendly for an "in draft" tunnel, and shouldn't cause speed dropouts or fluxuations in the flow when engaged, just like the blowers. So by MY definition, you should have the BEST sucker available!!! Quote Share this post Link to post Share on other sites
Paulipod 0 #28 November 10, 2004 Thanks I think so too... But when I say it pushes..... strictly speaking any recircultiing tunnel has a flow which is accelerated, then just topped up (ie.. when the flow is moving the ER is better) So what I meant was, in some ways this makes it irrelevant where the fan(s) is (hope that makes sense) But I would agree... I had had to pick a category... I am a sucker Bodyflight Bedford www.bodyflight.co.uk Quote Share this post Link to post Share on other sites
Bodyflight.Net 0 #29 November 10, 2004 Quotestrictly speaking any recircultiing tunnel has a flow which is accelerated, then just topped up actually only yours and one other, accelerate the air as it comes around, and there are at least a couple others that recirculate that don't accelerate, so again... your on top of the curve there too! But whos keeping score?? Quote Share this post Link to post Share on other sites
NickDG 23 #30 November 23, 2004 The first "wind tunnel" is attributed to the Wright Brothers who invented it. They used it to test the lifting ability of certain airfoils. Nowadays NASA uses a wind tunnel at the Ames Research Center in California that's the world's largest at 80 x 120 feet. Now turn that one up on its ear and imagine the possibilities. "Man, that 50-way was flying great, until it funneled trying to transition to the second point, and then it got real ugly . . . Nick BASE 194 Quote Share this post Link to post Share on other sites
Paulipod 0 #31 November 23, 2004 I wouldnt want to pay the electricity cost for generating 60m/s in a tunnel that size Bodyflight Bedford www.bodyflight.co.uk Quote Share this post Link to post Share on other sites
Bodyflight.Net 0 #32 November 23, 2004 Actually... the first wind tunnel was not invented by the Wright Brothers... however, they did use one first for testing airfoils. The first wind tunnel was invented in 1871 by Frank H. Wenham about 29 years before Wilbur & Orville got theirs going...http://www.bodyflight.net/history_1800-1916.html Ames can reach speeds of 250mph!!! Wouldn't THAT be fun... lol..

diablopilot 2 #34 November 25, 2004 QuoteI was talking about VWTs that SUCK. Which of course there are very few since the design itself causes instability in the air flow & test section.

Shoon 0 #36 December 9, 2004 Adren-L-N is a portable tunnel that F%*^ing Rocks. That blows away several permanent facility that are out there. Check it out www.adrenln.com/tv The lady is right you need to get out more, and learn to fly. Quote Share this post Link to post Share on other sites
