What will the future designs and skateboards look like? If the skateboards are to fly and operate like hover boards then chances are they will be quite a bit different from what we are used to. For instance we know that hover craft have an interior area underneath to trap the air in a ground effect fashion.
We also know that hovercraft blow low-pressure air underneath at one to two pounds per square inch. To lift a 200 pound person does not require too much air flow close to the ground while in the ground effect. But as the hover board gets higher the low-pressure area escapes and as the hover board moves faster the air gets away.
Any future design of hover boards will have to take all this into consideration. The mechanism which blows the air also takes up space and this will have to be part of the interior of the board. Therefore the board will have to be very light and hollow inside and a little thicker in or taller to contain the mechanical part.
Our drawings show 4-5 inches in height with 2 inches below the board. Additionally, hovercraft need quite a bit of air and therefore the board will have to be designed in such a way to collect the air as it moves forward with a series of air scoops and slats which help redirect the air into the interior mechanism.
Too much restriction of the airflow will cause the hover board not to work very well. This means the rider will not be satisfied with his speed, agility or performance of the hover board. The board will also need a spoiler system to dump the airflow it does not need at times, as do hover crafts.
The design must also allow the hover board to produce enough lift, through normal aircraft wing aerodynamic theory to support five times its weight during forward flight. A wing shape with side gates will need to be incorporated into the designs.
No airflow can be wasted and thus air which is blown underneath will need to be re-used through a series of design shaping strategies to force that air back along the aerodynamic structures of the hoverboard body.
The goal is to build a hover board which can travel like a hockey puck on and near table game board; very fast and maneuverable. Then use that speed to gain lift from the relative wind and use deflection strategies for maneuvers and tricks, jumping and clearing objects. Since forward flight does exist also the rider will employ angle of attack strategies as well.
If the rider decides to slow down or turn directions then they will simply pivot the board into the relative when and use that to slow down and change directions. During this transitional phase flight the airflow coming at the bottom of the hover board will need to be trapped and redirected back around through the turbines rather than fighting them so the rider can zoom off and the other direction.
All this is possible but it will radically change the design and looks of what we consider to be a modern-day skateboard. The futuristic design will be very cool looking and like nothing you have ever seen before. Will it fly? Yes and like nothing else you have ever seen either.
