"A hockey puck also known as LePuck will utilize aerodynamic and ground effect
forces
to reduce the friction that is found between the puck and the playing surface.
G Force
puck is cylindrical in shape with strategically located elliptical holes
positioned radially
around the periphery of the puck, with openings on the tap and bottom of the
radial
surface. The elliptical hole placements are symmetrical about the center plane
of the
puck, which is parallel, and midway between the two planar faces. This ensures
that
regardless of which planar face is interfacing with the playing surface the
hole orientation
is such that the ground effect forces are acting against the force of
friction. G Force Puck
also has circular pockets on each planar surface. The upper-most elliptical
holes exit to
the pocket on the opposing planar face and similarly the lower mast elliptical
holes exit
to the pocket on its opposing planar face. The upper most holes are positioned
such that
they are out of any boundary layer, or unmoving air mass, that may exist on
the playing
surface. This takes full advantage of the free stream air as the puck moves
across the
surface. The upper most holes will direct free stream airflow to the opposing
pocket and
thereby create ground effect forces that assist to counteract the frictional
forces found
between the puck and the playing surface. When the G-Force puck becomes
airborne, the
ducted airflow directed to the lower planar surface of the puck will have no
playing
surface contact, negating ground effects, and thereby forces an bath sides of
the puck will
be equalized. Airborne G-Force pucks will behave as per the desired flight
characteristics
of existing ice hockey pucks. The roller hockey version of G-Force puck will
also
incorporates low coefficient of friction coasters radially placed on the edge
of each planar
face to assist in minimizing the effects of friction. The reduction in
frictional forces will
allow consistent puck movement in game play, increase speed of puck movement,
will
minimize the effect of degrading playing surfaces on the puck behavior i.e
snow build-
up, chipped ice, debris) and increase puck life, while handling
characteristics will remain
unchanged. The G-Force puck will have different weights for different playing
surfaces,
age groups, and skill level".
