Ram Implosion Wing - Wind Tunnel Testing
I want to build the RIW and test it in a subsonic windtunnel, however, I was browing the forums and everybody is calling it a scam. Has this been proven to be a scam? Should I not try testing this? I don't want to waste my resources on a scam. Why do you guys think this would fail, do you have any legitimate reasons?:confused::confused::confused:

I'm serious about this, I will actually test it. I just want some feedback before I do.

Read this first: http://ecomodder.com/forum/showthrea...ngs-17139.html

I read it, but I don't think it's supposed to create thrust by improving the aerodynamic fluidity. It's supposed to create a vortex in front of the car, thus reducing air pressure, I'm not an expert but I think we have to look at it from another angle.

Or mount it in place of a kammback, where it would work, but be out performed by a sheet of cardboard. |
I'm actually going to be building a miniaturized version of this and mounting it on a car model, not an actual car. And then I'm going to test it in a mini wind tunnel. I don't have the resources to build a full scale wind tunnel, and RIW. I'm still a high school student.

Sometimes, logic is incomplete, and people are proven wrong. Sometimes, logic is valid, but testing provides credibility logic sometimes lacks.
Good luck! |
troll?

Test this in a wind tunnel? I think you risk a runaway reaction that would create a wormhole that would take you off into cloud cuckoo land, where you would meet the inventor of this thing and you could write some testimonials together.

Implosion, indeed. I think a few IQ points just vaporized.
I anticipate a change of address for this thread. |
Wind tunnel guy, I see you're still young and learning about new things. One of the things you need to teach yourself is how to be skeptical of things that claim results that seem outside the realm of possibility. One of the biggest clues you'll find that lead you to be skeptical is people using terms that seem scientific, but are really just patent Bull Crap.
The 2 things you wrote that make me say "What the heck?" are "Aerodynamic fluidity" and "Create vortex in front of the car". It is good that you are curious about aerodynamics! We all start somewhere. I suggest you read a lot of the things Aerohead has written about and explore what we can do to a vehicle in order to reduce the drag forces created by moving a solid object at high speeds through the air. There is a lot to learn just to start understanding the basics of aerodynamics. This Ram Implosion device thing you speak of is an attempt by some to confuse you with scientific statements which sound reasonable, but, in fact and by just plain logic are false or it's supposed effects are hugely over exaggerated. Welcome to ecomodder. Don't let the snide comments here dissuade you from learning more about this very interesting field of study. I started out with my own huge misconceptions 4 years ago and have learned a ton since then. If you really want to learn, forget this Ram Implosion thing for now. Be grateful for the fact that it has led you here, and start learning my young friend. If you try to defend the Ram, you'll only be met with greater and greater hostility which will certainly frustrate you and send you off thinking that we're all a bunch of closed minded mean people here, which we are, :rolleyes: but given the right chance, we can teach you a whole bunch. :thumbup: Much respect, Charlie |
OP -- Vortexes don't work that way.
What I'm curious about is your [proposed] wind tunnel. What scale will it work at? Most are 1/4th to 1/10th; but the horsepower requirement goes up*. There was a guy in Japan who had videos on Youtube showing his work at 1/24th, but I think they're gone. He had digital scales under each wheel and one to get pushed at the back. He couldn't derive absolute values, but could do A-B comparisons. *There are losses involved, so a full scale wind tunnel will consume 1000s of horsepower. |
I have not seen this before - and I am sorry I did.

*The last thing in the world that you'd want,is a vortex in front of the car.This would destroy the flow all over the car. *The 'high' pressure in front of cars is not a problem and never will be. *The problem is the low base pressure behind the car,something the RIW cannot address. *The RIW fails theoretically.It's performance premise is completely removed from the realities of physics. *You'd do just as well to paint your car Baker-Miller Pink. |
^^
Made me look up Baker-Miller Pink. Weird stuff. Not knowing the history of B-M Pink or Drunk Tank Pink, I tried a shade of pink a few years ago based on my own theories and suppositions: Sherwin-Williams "Little Princess," very nice in my opinion, fairly pale to make the most of poor lighting. I had a volunteer crew paint a stairwell leading to the overnight dorms in the homeless shelter where I work. The reaction was so unpleasant I painted it back to grey. That was ten years ago. I've repainted in there at least once since then, and it's still grey. It may not be calming, but it doesn't induce rage either. |
The most manly pink is Mountbatten Pink (#997A8D)

I have read that Mikoyan-Gurevich cockpits were painted in a sea-foam green for the very same reason.

green

If you're in a daylight dogfight and glancing back and forth,from a high-altitude clear sky background to the instrument cluster,the retina would experience a more uniform lighting level maintaining good visual acuity. If the green is also calming,that would be a plus,given the work environment of a fighter pilot.:p |
Obviously you need a pink implosion wing!
I would drive the dog van from Dumb and Dumber if it doubled my mileage, but when I told my "mother-in-law" that I broke 50 MPG on my previous tank she just shrugged it off. |
Quote:
I find it easier to tell people how much money I saved as most people can relate to money in their pocket compared to MPG. Fer example, I've saved between $500 to $700 in fuel costs every year (6 years) since I started aero modding my T-100...which has paid fer the purchase of my truck and ALL mods to date. My long road trips calculated out to $0.09 per mile. ;) |
A quick note to InnovativeWindTunnelGuy:
If you're an actual wind tunnel guy, I think you'll appreciate that we prefer testing and documented results over rhetoric and anecdotes. The "inventor" claims double and even triple the usual fuel mileage for vehicles using his device, and that it works better at higher speeds. If you spend much time here you'll see that that flies in the face of our usual philosophies. Doubling one's usual fuel mileage is the holy grail, tripling is the essence of the Unicorn Hunt. To date I can only imagine one guy could claim having done that: Diesel Dave in the White Whale, and his posted average speeds are the epitome of "modest." The "inventor" uses a lot of gobblydegook to talk about his creation. Many of the terms make no sense whatsoever, even if you assume they are sort-of contextually appropriate. For further exploration of this concept see: https://www.youtube.com/watch?v=rLDg...?v=rLDgQg6bq7o But don't let us dissuade you. We're all about testing, here. Test, document, test again. Test with and test without. Eliminate as many other variables as humanly possible. And then tell us what you've learned. It would be quite something to discover if there were an actual unicorn, and that it was useful. |

Ha Ha- The ORIGINAL ricer speed holes!

Aerohead, I am embeding your image to view it! :D

Wouldn't that create excess wind noise? If it makes wind noise, wouldn't it be creating drag?
|
A brick wall with a hole in it will make more wind noise than a flat brick wall, but it will still have less drag. :D

A true sky-ripper! Waring blender.'Bass-O-Matic.'"Holy Parachutes Batman!" After the 1/4-mile run,they probably took their hole saw out to the desert and used it for target practice. Smokey Yunick acid-dipped his cars for weight reduction,maintaining their aerodynamics (of which he cheated on).:D |
As a parent of teens I see no harm in trying an experiment using a model and a leaf blower. I think that the lesson in critical thinking and experiment design will prove useful. That said, I believe the device will not live up to claims. This is how we learned there was no such thing as the ether medium in space. I have done some rather counterintuitive things in my life such as roast a marshmallow between my fingers without getting burned and building fairings for mountain bikes immune to side winds.
