Adjustable Spoiler

[LSX-438]

Interesting stuff. Do you know of anyone running these wings (active or static) in any aussie CAMS sanctioned event? I have asked our eligilibility officer to look into it, for the 2010 season.

Fair enough. I am still a sceptic though as I think if it was such an advantage it would have been more widely used in motorsport.

We have done further research today on the use of active aero on various supercars, and have added more info to our "The History Of Active Aero" article here ...

http://www.tunersgroup.com/active_aero_history.html

That new section on that page reads ...

--------

There are a number of supercars that run active aero, some of them at the higher end of the price range and not frequently seen, so many people don't know that they run active aero ...

Bugatti Veyron

The Bugatti Veyron's active rear wing changes height and angle of attack. Adding height to the wing moves it into cleaner air (making it more effective), and adding angle increases the downforce coefficient of the airfoil (blade).

McLaren F1 Roadcar

The McLaren F1 roadcar also changes the angle of attack of it's rear wing.

http://en.wikipedia.org/wiki/McLaren_F1 reads ...

There is a small rear spoiler on the tail of the vehicle, which is dynamic, the device will adjust dynamically and automatically attempt to balance the center of gravity of the car under braking – which will be shifted forward when the brakes are applied.

Porsche Panamera

The Porsche Panamera also uses active aero.

http://www.autoblog.com/2009/06/25/first-d...78-years-in-th/ reads ...

Active aerodynamics are standard equipment on all variants of the Panamera, but they alter slightly based on trim level.

The Panarama S and 4S feature a one-piece rear spoiler that is retracted and flush with the bodywork until the sedan reaches 56 mph, at which point it moves into an angle of -3 degrees.

At 100 mph, the wing angle lifts to +5 degrees to increase downforce. At 127 mph the spoiler moves to its maximum deflection of +14 degrees.

The spoiler on the Turbo model is fitted with two additional flaps that extend to increase surface area. It too deploys to -3 degrees at 56 mph, but then locks at +10 degrees at 127 mph and up.

Ferrari 458 Italia

The Ferrari 458 Italia also uses active aero.

http://news.teamxbox.com/xbox/21027/Forza-...-Screens-Video/ reads ...

The 458 Italia is a combination of banned F1 active-aero technology and the voluptuous vision of the Pininfarina design house. The Ferrari features ‘aerolastic’ spoilers in front that shape shift as the car accelerates altering the flow of air into the radiator and decreasing drag.

Honda

Honda is also working on active aero.

http://www.autocar.co.uk/News/NewsArticle/...oncepts/244309/ reads ...

Honda is working on active aerodynamics for its next generation of cars, and will introduce the technology within five years.

Nobuki Ebisawa, Honda's R and D managing director, said active aero would be introduced to get away from the high, cut off tail that characterises cars such as the Insight and forthcoming CR-Z.

Hi Duncan,

As far as I know no cars in Australia are running them yet, but as detailed earlier in this thread they are being used on a bunch of cars in the US.

There are also a number of cars running them in Asia already ...

We will be speaking to CAMS later this week to help familiarise CAMS and their scrutineers with the Aeromotions wings.

Sounds like some pretty impressed customers there and definatly some positive feed back. Are all their wings a generic design or are they model specific as i would be interested in pricing on a static wing for my R33GTR if they are available as i have been looking into options for my track car and have mainly been looking at some of the japanese product available. I would also like to know what the actual weight of the wings are if possible.

[LSX-438]

ok, will be interesting to see how you go. You may want to review cams sports sedans rules before talking to them. I noticed in the marketing stuff for aeromotions you can run the wing in a fixed position to satisfy racing regs, say for a given meeting, please ask them if they would allow that (if you get an initial negative response) i will be interested to know. my email address is duncan_forrest at optushome.com.au please emai me your pricing and availability for the fixed and dynamic wing. (non-split versions). FWIW i think CAMS regs will exclude spilt designs entirely.

Hi Dazmo,

For all models of the Aeromotions wings, a universal version is available as well as the model specific versions.

So currently the available versions of each wing are:

- Nissan Skyline R35 GT-R

- BMW 3 series E36

- BMW 3 series E46

- Corvette C5

- Honda S2000

- Mitsubishi Evolution 8

- Mitsubishi Evolution 9

- Universal version

I would also like to know what the actual weight of the wings are if possible.

The single element R2 Static weighs 5.7 kg (12.5 lb)

The single element R2 Dynamic Wing weighs 7.9 kg (17.5 lb)

The split element S2 Dynamic Wing weighs just 4.7 kg (11.0 lb)

The weight savings on the S2 Dynamic are achieved by using teardrop shaped uprights from an airplane, Formula 1 grade dry pre-preg carbon fiber, and titanium internals.

We have put together a comparison matrix for each of the wings here, showing specs, weight comparisons etc for all the Aeromotions wings ...

http://www.tunersgroup.com/Products/aeromotions_matrix.html

The pages with full product info about each wing are also now online ...

The single element R2 Static is here ... http://www.tunersgroup.com/Products/aeromo..._r2_static.html

Hi Dazmo,

We have been finalising pricing this week.

Pricing for our US customers is here ...

http://www.tunersgroup.com/Products/aeromo...pricing_US.html

AUSTRALIAN PRICING

As I wrote earlier in this thread, "As always, our Australian pricing will be as close as possible to prices in the US where Aeromotions is based."

Australian prices ex shipping will be roughly equivalent to the US prices above plus import duty and GST. The landed price will vary slightly depending on which part of Australia a wing is being delivered to.

We can arrange customs clearance etc so that customers do not need to deal with the time consuming process of doing a formal customs entry, which also helps our customers avoid the lengthy delays that can happen in customs clearance.

Our customs broker is currently checking on the exact duty rates etc so that we can have exact Australian prices. Similarly our shipping companies are working out the best options for shipping. They should all be finalised this week.

Given that the S2 Static Wing is priced for our US customers at US$1699 and this post posted by a driver with an S2 Static Wing on an R35 GT-R http://www.nagtroc.org/forums/index.php?sh...st&p=472311 reads ...

My GT-R was transformed with the wing. I dropped 1.5 seconds on a 1:20 course at Roebling Road, and the difference in feel is immediately noticable ... I am running the static wing for now.

... that's very good value for a potential drop in lap time of that magnitude.

I am keen for a wing, please send me a price delivered to postcode 2035 duncan_forrest at optushome.com.au

i need two quotes, one for a fixed version and the other the dynamic (i dont think i can run the split version). You should get lots of exposure next year we plan on lots of video work showing all components on the car! cheers.

Cool video GTOMR !

I also just found an article on TMR about the Aeromotions Dynamic Wings with some additional info about how they were developed ...

I LOL'd when I saw this part of the article ...

Despite all the hard parkers you see cruising your local entertainment district on a Friday night, a rear wing is actually useful for more than just a place to rest your cup of Coke if you’re driving your modified car at the track, not just to McDonald’s. This wing appears to be the next step in aerodynamics for motorsport enthusiasts.

Hi LSX-438,

The data from the Thunderhill test mentioned above produced the following lap times (the wing used in this test was the split wing, running in 3 different configurations):

- Without Aeromotions Wing: 2 minutes 10.1 seconds

- With Aeromotions Static Wing: 2 minutes 9.2 seconds

- With Aeromotions Dynamic Wing : 2 Minutes 8.4 seconds

- With Aeromotions Dynamic Wing With Centre Fence): 2 minutes 7.7 seconds.

So lap times with the Aeromotions Dynamic Wing running in dynamic mode were 0.8 seconds a lap faster than the wing running in Static mode.

And lap times with the Aeromotions Dynamic Wing With Centre Fence were 0.7 seconds a lap faster than the wing running in in dynamic mode with no centrefence.

What I found really interesting there is that the simple addition of the centre fence cut 0.7 seconds off the lap time compared to running the split wing in dynamic mode with no centrefence. The centre fence is the vertical plate that runs between the centre of the two split elements - see photo above.

The reason for that is that a centre fence isolates the airflow over each half of the split wing, and can have a huge effect on increasing aero efficiency and cleaning up aero flow. That then lets each half of the split wing to work more efficiently than without the centre fence.

That concept is the same reason that the Boeing 747-400 and Airbus A380 run upturned wingtips on the ends of their wings. This effect was also mentioned in the Richard Hammond show on SBS a few weeks back about the development of the A380.

Above is a photo of the wing tips from an Airbus A380.

There is a diagram here of the effect on airflow ...

There is an article on Wikipedia about that effect here ... http://en.wikipedia.org/wiki/Wingtip_device

It reads ...

Quite a few other planes run upturned wingtips for the same reason ...

I'll check with Aeromotions to see if they have data available about the difference in performance between the single element Dynamic Wing and the split element Dynamic Wing. Given that the simple addition of a centrefence on the split wing cut 0.7 seconds from the lap time though, I wouldn't be at all surprised to see a very significant difference in lap times between the split element wing and single element wing.

And the airbus stole it from eagles. So in turn we owe faster lap times to a bird and generations of evolution

Top of the line Aeromotions S2 split wing, awesome stuff. about 8k aus. Some spend almost that on a carbon fibre lip or rear spoiler with no added aerodynamic benefit so probably not insane price for something with this level of functionality. I suspect a few track guys here would be interested in this, it seems to provide noticeable results

Were can i get myself a aeromotions S2 split wing for my R35?
