Schuberth

Schuberth Engineering AG in Braunschweig, Germany, develops and manufactures high-tech helmets that are also preferred by many Formula 1 teams. Michael Schumacher, Rubens Barrichello, Ralf Schumacher and Nick Heidfeld rely on the individual and tailor-made helmets.
For tailor-made manufacturing, the 3D digitizing system ATOS II, a product of GOM, records the shape of the racing driver's head precisely, quickly and completely.
During a Formula 1 race, forces occur that are four times the amount of the gravitational acceleration. In order to allow for best possible protection, convenient wearing and mobility, a light, stable and compact helmet is required that is individually adapted in shape and upholstery. For this purpose, a special layered structure with a high-performance carbon fiber is used, the material of which the Formula 1 monocoque chassis are made of as well.
For optimizing the shape of the helmet, reducing its weight and improving aerodynamics, it is important to precisely and completely record the individual shape of the driver's head.
Due to the Schuberth technology and the GOM measuring system, Rubens Barrichello's helmet just weighs 1050 grams and thus is about 500 g lighter than his old helmet. That way, during a race, the muscles of the neck are essentially relieved. The slender form of the helmet results in less air resistance and better streaming to the air box. Therefore, an increased power of 10 HP is available.

Arai

The GP-5 is the result of Arai's pursuit of a comprehensive package, one providing comfort and function in an attractive package while masking the hidden energy-management system within.
Incorporates Arai's exclusive, premium Sclc2 (Super Complex Laminate Construction) shell technology. Because of this proprientary aerospace fiberglass composite, the GP-5 offers the benefits of improved impact-energy management properties, as well as low helmet weight without the use of trendy lightweight materials which may not be properly suited for use in helmet applications.

is this thread a joke?

It's Arai? I thought it was Aral.

is this thread a joke?
Why is it a joke? Not alot of people know the difference.
It's Arai? I thought it was Aral.
Yea it's Arai.



EDIT: just a side note, Schuberth claims their helmet is bulletproof.

They both look similar, but my choice would be "Arai".

I love those helmets...hehe.

Also, it was proven that Arai's helmet is supposingly more *aerodynamic*. But i'm not too sure about that being correct.

Well they have those little spoiler's you can add to the GP-5 helmet, that will make it more aerodynamic.

M. Schumacher, did a lot of testing, to make his helmet aerodynamik!
but i choose Arai, the only one i know!... and its the helmet choise of Hamilton ;)

I choose Arai, mainly becuase it's the only one I've heard of. Also it's the helmet that saved Richard Hamonds life (kinda). They both do the same job so it doensn't matter really.

^Yeah they both do the same job so there's not really any difference them to be honest? But a 10hp increase due to the helmet shape? I'm a bit sceptical about that one...

^ Yeah, pretty soon, your hairstyle will determine whether you win or not:p

im sorry but this thread is a waste of space.

If you dont want to participate in this thread rather than whine about it than leave it alone. Some people actually have NEVER heard of Schuberth at all. So, in this case, it's not a waste of space.

The schuberth is more aerodynamic when used in an open wheel race car, than the Arai. They are both pretty much bullet proof these days, both use a lot of kevlar and Carbon Fiber, not fiberglass like the old days or the 100-500 dollar helmets you buy around.

As far as comfort goes, the Arai will cool your head a lot more than the Schuberth. Visibility wise they are pretty much the same thing.

the other difference is price, the schuberth is a lot more expensive than the arai, in that f1 racing trim, hence the hans device attachment built into the helmet and not as detachable as the arai.

Over all I have had both, and the new Arai Gp5 is one expensive mofo but man is it nice, to feel the air going into your head, especially while driving on the bike.

^Yeah they both do the same job so there's not really any difference them to be honest? But a 10hp increase due to the helmet shape? I'm a bit skeptical about that one...

Its based on how your helmet helps funnel air into the intake positioned above the drivers head in F1. If you helmet disturbs the air flow, you will end up getting turbulent air entering the intake, which can reduce the amount of air entering the combustion chamber, it can also create a vortex which will induce a pocket of air preventing air form entering the intake.

On the other hand if your helmet can streamline the air flow and not disrupt this flow, create more of a laminar flow you will be able to obtain a steady air flow to the combustion chamber. Thats pretty much how they claim the 10hp difference.

sorry for the double post

LOL, the GP-5 is *supposingly* for auto racing, heh.

^^^ yeah I know, but when you get a free arai gp5 from someone that does not know what the hell its used for, you just smile say thank you and take them out to dinner and a movie.

^^ LOL. You got a free Arai helmet? nice...

To me they are both helmets and are there for a reason. If they do their job they would work for me.

So in this comparo, I obviously have to choose the "better" one. This of course is the Ferrari colored Schuberth. A thing of beauty within itself.

^^ LOL. You got a free Arai helmet? nice...

I want one for free...:p.

...Also I was wondering is there a difference in the Moto helmet than in an Auto one?

or just as long as it protects your head :P

...'cause I have a Moto one, was only $22 bucks at a swap meet, used but looks fine.

I know for a fact that the Schuberth is damn near indestructible b/c a tank ran over it without any damage to the integrity of the helmet. Then based on how many aerodynamists choose Arai over another brand based on the aero efficiency that would be another way to go. Overall I'd have to personally try both to see how the weight of the helmet felt on the neck muscles. Whichever felt better as far as weight distribution and comfort level would be my pick. Honestly how much could a tiny little head hinder the aerodynamics of a car? All of these helmets have to be aerodynamic to a certain degree.

Cooper "S" explained why. read what he posted on the first page.

Helmet shape also has effects on the rearward aerodynamics, and is as important piece of the whole car as the wing mirrors. If the car is not designed with the helmet in mind, or vis versa, you can get some serious repercussion in terms of the airflow towards the rear of the car.

An example of the aerodynamics of the helmet in conjunction with the car can be seen on Hamilton's helmet in the 1st post. See that small addition to the rear of the helmet? That is supposed to line up with the part that holds the headrest, ensuring that any air traveling over the helmet isn't thrown off or made turbulent and draggy as a result. By doing that, the air is more manageable and predictable, and comes with minimal drag effects.

^Thanks Timbit and of course Cooper S for explaining, at first I thought that 10hp was a bit far fetched to be honest, but now it's seeming more believable.

In response to Timbits very detailed post. Here's a picture i drew to interpret what i think he intended to say for the air flow. As my Drafting teacher said, 'Picture is worth a thousand words"
More air to the intake = more power.

Not exactly. I hope this image explains what I meant graphically:

As crudely formed that image was, it shows what I meant. The added part of the wing acts as an extension of the headrest, in that it bridges the gap that is left in a conventional helmet, this making the air more manageable and less prone to becoming turbulent.

Have a look at Trulli's (quite awesome) helmet in this pic from Brazil:

You can clearly see the flap at the back (in a very awesome clear), and you can also see how well it lines up with the head rest-majiger.

Keep in mind though that there probably isn't a huge penalty to run without a helmet flap. Kimi and Ralf both use helmets that don't have any additional aero bits on them. The teams would probably decide prior to each year's car on whether to design their cars with the flap in mind, or whether their time is better spent making gains elsewhere.

Very nice explanations guys. Thanks Timbit and Cooper S for explaining this. Also nice pic Timbit. Great!

I want one for free...:p.

I'm not so sure. There should be a difference or else they would just sell the same design for both categories.

Well for one, the HANS system isn't available on a Moto Helmet.
