Starting with Generic Hovercraft
Replacing group of the rubber coated skirts with vinyl
coated, mixed vinyl up/ rubber down, and HoverCollege's Teflon double coated
skirts.
|
|
Challenges
|

Hovering between frozen water surfaces over water gaps
in -15c under snowy condition.
|

High speed front drag, -15c, 50` depth
|
|

On icy water -5c
|
|



Snow setting -30c
|

Immediate Hovering after 7 days Snow setting
|

Setting over water turned into ice for 3 days
|
|

Repeated land water transition on deferent speeds
|

Jumping from deferent levels of the road on full
cushion
|

Low cushion test over gravels

High friction test on 23 degrees up hill over sharp
obstacles
|
|
Calibration Tools
|

Specially designed clear skirt for monitoring hovering
behavior
|

Tracking measuring for skirt/surface friction
behavior.
|
|
High speed racing boat for drag test, Garmin 120 GPS
|
|
Observations
|
 
 
Sharp Obstacle test most skirts deteriorated except
Double Coated Teflon Skirt still Usable
|
After Road jump Double Coated Teflon Skirt is the best
holding shape
|
|

Both rubber and vinyl are ripped after Snow setting
Double Coated Teflon Skirt still Usable
|
|
 
After the Frozen water test regular skirt ripped
Teflon proved ability to slick from sticky situations.
|

Double Coated Teflon Skirt proved to be able to hold
firm and slide from the snow setting faster
|

After the jump over full cushion Double Coated Teflon
Skirt proved better hull protection against regular skirt
|
|
 
because inside regular skirts is not coated it
collects amble snow to hold the hovercraft down and rip the skirt
|
 
with increasing the air pressure the snow did not pass
throw, the regular skirt got off.
|
The amount of snow collected in Un-coated inner skirt
is enough to maintain solid connection with the ground all the times.
|
|

Clear Skirt showed the tendency of Double Coated
Teflon Skirt to take bigger space with low pressure.
Also show the snow with in uncoated back skirt that
hold the hovercraft rear down.
|

Clear Skirt shows the ability of the Double Coated
Teflon Skirt to hold shape after the pressure is off.
|
|
Without Double Coated Teflon Skirt the front drag effect is clear and
the hovercraft front climb up the rare sinks, that slows the hovercraft
and keeps friction contact with surface.
|
With hybrid skirt for test it is clear that front drag is high with
regular skirt, very low with Double Coated Teflon Skirt (red) this allow
the rare to rise up and maintain full hovering.
The Low Friction of Double Coated Teflon Skirt Allows the following:
- Low Friction with water
- Low Friction with obstacles
- Low Friction with Ice
- Low Friction with the pressured air
- Low Friction with other skirts
