More Dimples from the Tech corner


The other week we posted a scientific video that confirmed that a golfball (or floorball) with dimples have like 50% less drag..
It is just a fact. Nothing to mess with...

Now look at this...



In principle we could take any floorball blade for this discussion but - I just took the blade I use myself.

Our question is - how large is the surface of this stick? Of course they know at Salming.. but let us try to speculate and just guess a bit..

The depth of the blade is like, about 5-7 Millimeters so let us assume about 6 mm.  In principle we have like 5 bars roughly 230 millimeters long. Plus minus 5 -10% maybe?
Then all bars have an upper side and a lower face plus a leading edge and a tail edge - for the sake of easy math say one mill each for the edges. Then toss in like plus 20% for ornaments, wider areas and extra small bars and the fitting to the shaft... etc etc ,, sounds fair?

OK, 6 x 10 = 60
plus 2 x 10 = 20   this is for a crosscut at like 80 together, add 230 for the length and... 18.400 mm square plus 20%... yup: 22.080 square-millimeters seems to be a rough estimate of the surface of this blade..

Now let us do the ball - the Floorball ball - we take Pie times 72 x 72 to get the sphere area - size of the square = 16277.76 Square millimeters... Let us toss out like 10% for the 26 holes and we are at... like 14,560 square mils.. for a regular Floorball ball approx.

This estimate shows that the surface of a Floorball stick flying through that air is like roughly 44 percent larger than the ball - yes you may toss in a bit of the lower shaft too and we are probably well above 50% in size of area - compared to the ball - as an area flying through the air as you shoot hard.

You know what - that blade goes as fast as the ball through the air as we shoot slapshots - YES IT DOES if not EVEN a BIT FASTER
... the ball has dimples- since we know it will reduce drag with about 50%,,,,

Are we fully crazy here ? Sure as always!

To us it seems obvious that the Floorball blade and the lower part of the Floorball stick seems to be in much more need of dimples than any Floorball ball in the world -  if we want to shoot as hard as we can - with as little effort as possible?
This seems wrong..as the stick of today has been designed. We do not know about one single manufacturer that use dimples on their sticks...

So let us yet again challenge all Floorball producers in the world - Who will be first with a blade and the lower part of a stick to be filled with dimples? Just like a golfball?

If you do not agree on this - well come on and argue against us - unfortunately we think we are right -

and other improvements ideas like these we must sort in under the more wacky label http://www.google.com/patents/EP0877641A1?cl=en - wow... kinda. dimples in the blade would in essence include what these guys tries to obtain...

Now some patent trolls may steal this idea to be used in Tennis, Squash, Golf and Hockey too - why not lacrosse too? - That is fine since they will not be able to come up with the next thing  nor stay ahead of us lol

Caution

Research suggest that eye-injuries are more common in Floorball as compared to Tennis, but less common as compared to Squash (similar to Racquetball).
To minimize this risk of injury Floorballcentral recommend: Use certified protective eye-wear (mandated in many European areas for the youth). Do not lay down on the court. Follow the rules strict on stick height.

Also if you get addicted to this sport - do not blame us!
