One of my first questions when I got there was if there were large energy losses in the turn vanes. Norm said that usually energy losses associated with turning air is enormous, however with the skyventure design, they have reduced the energy losses considerably. They had a number of experts in the field work on the design and this was the final product. Apparently what they caome up with was so innovative that NASA is interested in the technology.

Perris, Orlando and Eloy are open air tunnels, they are all located in climates that are pretty well stable temp wise. Airkix,Colorado and New Hampshire (i think that is the other one going up) are recirculating tunnels that are in climates can be colder. Making them recirculate they can use the heat off the motors to heat the air in the chamber. The temps can be controlled by opening and closing the outside air intake to bring in more cool air as needed.

The "standard" design SkyVenture tunnels are all "total loss" systems. They suck air in from the bottom, through the venturi (flying chamber) and blow it out the top after it passes the electric motors. The Colorado design is a recirculating tunnel, as is the one on Fort Bragg (though it looks totally different) and, I am assuming, the Bedford tunnel.

Quote Share this post Link to post Share on other sites Bodyflight.Net 0 #119 September 23, 2005 that should depend on where you are standing.. it should be significantly quieter for spectators and outside observation.. but inside the chamber I'm estimating that it's the same to a bit louder because the sound is being contained & recirculated with the air. Quote Share this post Link to post Share on other sites davedlg 0 #120 September 23, 2005 QuoteAnyone know if the recirculating tunnels are quieter? The Perris tunnel struck me as being just a little too noisy for a built-up area. I know that there is quite a bit of noise dampening built into the diffuser. Norm had me walk up to one of the diffuser pieces (they are the big metal pieces in the foreground of this picture) and yell into it....It completely absorbed the noise - there was absolutely no echo whatsoever. How much noise it will make remains to be seen, but I have to imagine it will be much quieter than a non-recirculating tunnel. Quote Share this post Link to post Share on other sites GQ_jumper 4 #121 September 23, 2005 The majority of the noise in open tunnels comes from the air passing over the net, the re-circulating tunnel will still have the net but it won't have the one at the bottom of the opening like the open ones do, so one less net may very well greatly reduce the noise.

Eisenhower Quote Share this post Link to post Share on other sites flyangel2 2 #122 September 23, 2005 Speaking of nets. Norm was telling me that the wire (if that's what you would call that) on the net has been changed out at the tunnel in Florida and it seems that the material used for the net added to the noise level. The Colorado tunnel will be using the same material that is being used in Florida's tunnel. Dawn, I too stood in the area that Dave was talking about and yelled. I was shocked how quiet it was. You'll just have to head out this way this winter and give it a try and then hit the slopes with me.

Or so I've been told, I didn't get to go into the Orlando tunnel before it was change but it is definitely quieter than the bragg tunnel which has a bunch of ropes going across it.History does not long entrust the care of freedom to the weak or the timid. --Dwight D.

But majority of the noise will come from the fan blades for sure! Interesting talk on the net though The noise output from the blades is directly linked to the number of blades/rpm of the fan. With this you get the frequency of the noise which is also a key factor... Bodyflight Bedford www.bodyflight.co.uk Quote Share this post Link to post Share on other sites Bodyflight.Net 0 #125 September 24, 2005 fan blades don't tend to make as much noise as props do although I remember something about bearings I think it is that makes the fans loud. all nets sing at high speed, that's what I call it anyway.. we know the SV net is a major source of noise because without it the tunnel is refreshingly quiet the new net has a cable wrapped around it (each strand).. reminds me of the thread on a screw.. works very nicely..although I haven't heard it installed I only know about the testing before hand.

Least that is my guess Edited for typo and shitty spelling, im sure there is more I missed too She is not a "Dumb Blonde" - She is a "Light-Haired Detour Off The Information Superhighway." eeneR TF#72, FB#4130, Incauto Quote Share this post Link to post Share on other sites
SkymonkeyONE 3 #116 September 22, 2005 QuoteDoes anyone know why the Airkix (Milton Keynes, UK) and Colorado tunnels are so superficially different to the Perris, Orlando, and Eloy tunnels? The "standard" design SkyVenture tunnels are all "total loss" systems. They suck air in from the bottom, through the venturi (flying chamber) and blow it out the top after it passes the electric motors. The Colorado design is a recirculating tunnel, as is the one on Fort Bragg (though it looks totally different) and, I am assuming, the Bedford tunnel.

bob.dino 0 #118 September 23, 2005 Thanks one and all! Anyone know if the recirculating tunnels are quieter? The Perris tunnel struck me as being just a little too noisy for a built-up area. Quote Share this post Link to post Share on other sites
Bodyflight.Net 0 #119 September 23, 2005 that should depend on where you are standing.. it should be significantly quieter for spectators and outside observation.. but inside the chamber I'm estimating that it's the same to a bit louder because the sound is being contained & recirculated with the air.

davedlg 0 #120 September 23, 2005 QuoteAnyone know if the recirculating tunnels are quieter? The Perris tunnel struck me as being just a little too noisy for a built-up area. I know that there is quite a bit of noise dampening built into the diffuser. Norm had me walk up to one of the diffuser pieces (they are the big metal pieces in the foreground of this picture) and yell into it....It completely absorbed the noise - there was absolutely no echo whatsoever. How much noise it will make remains to be seen, but I have to imagine it will be much quieter than a non-recirculating tunnel. Quote Share this post Link to post Share on other sites
GQ_jumper 4 #121 September 23, 2005 The majority of the noise in open tunnels comes from the air passing over the net, the re-circulating tunnel will still have the net but it won't have the one at the bottom of the opening like the open ones do, so one less net may very well greatly reduce the noise. I would love to fly in a tunnel quiet enough for other people to hear me swearing when I bounce off the wallsHistory does not long entrust the care of freedom to the weak or the timid. --Dwight D.

flyangel2 2 #122 September 23, 2005 Speaking of nets. Norm was telling me that the wire (if that's what you would call that) on the net has been changed out at the tunnel in Florida and it seems that the material used for the net added to the noise level. The Colorado tunnel will be using the same material that is being used in Florida's tunnel. Dawn, I too stood in the area that Dave was talking about and yelled. I was shocked how quiet it was. You'll just have to head out this way this winter and give it a try and then hit the slopes with me.

GQ_jumper 4 #123 September 23, 2005 The difference in the new type of wire is that there is an extra cable coiled into it in a way that allows air to pass more cleanly around it. Or so I've been told, I didn't get to go into the Orlando tunnel before it was change but it is definitely quieter than the bragg tunnel which has a bunch of ropes going across it.History does not long entrust the care of freedom to the weak or the timid. --Dwight D.

Paulipod 0 #124 September 23, 2005 Dont want to throw the cat amongst the pidgeons too much.... But majority of the noise will come from the fan blades for sure! Interesting talk on the net though The noise output from the blades is directly linked to the number of blades/rpm of the fan. With this you get the frequency of the noise which is also a key factor... Bodyflight Bedford www.bodyflight.co.uk Quote Share this post Link to post Share on other sites
Bodyflight.Net 0 #125 September 24, 2005 fan blades don't tend to make as much noise as props do although I remember something about bearings I think it is that makes the fans loud. all nets sing at high speed, that's what I call it anyway.. we know the SV net is a major source of noise because without it the tunnel is refreshingly quiet the new net has a cable wrapped around it (each strand).. reminds me of the thread on a screw.. works very nicely..although I haven't heard it installed I only know about the testing before hand.
