Hovercollege and Hovercraft Frequently Asked Questions
We are sure you found tons of Hovercraft and Air-Cushion
related FAQs through the internet, However, at HoverCollege we've distinctive phrasing
techniques in our answers and explanations, we always feature this methodology
in all our Hovercraft Courses, for not being
repetitive we'll only feature distinctive FAQ that are not usually in any other
FAQ or not explained according to our popular Academic-Industrial amalgamation Methodology.
What is the deference between HoverCollege and other academic institutes?
-
HoverCollege is recognized by many advanced methodologies,
for example; HoverCollege uses Science and Industry to serve and improve the
Hovercraft technology instead of using the Hovercraft just as a preliminary
example for science theories like other institutes, HoverCollege offers all
the courses online, you can access your study in HoverCollege from any
country around the world, HoverCollege generates Highly Knowledgeable
Hovercraft Builders, neither Academics in ivory tower nor Hovercrafters who
built their knowledge on try and hits.
What is Hump speed and is the same definition could be applied
on solid ground?
- According to Dr. Rushwan's Ph.D. Thesis; "Hump speed is the speed
that will not allow the ground media under the Hovercraft getting enough
time to deform and shape in response to the Hovercraft distributed weight
Displacement, it’s the hardest over fresh water and the easiest over
Skating rank"...why?
Fresh water as a liquid shapes waves in front of the Hovercraft to allows
the compressed air under the Hovercraft to take enough displacement mass
inside the water to float, these waves builds drag resistance " which
is one of the reasons why HoverCollege invented the Hoverfabric and the
Teflon Skirt" this wave drag becomes harder and harder as the speed
accelerates, the same scenario exactly as in breaking the sound barrier, and
all the sudden the liquid gave up and there is no enough time for the water
to form the wave, the Hovercraft starts to ride over it’s own wave,
passing the wave even before it starts to shape instead of chasing and
racing it like other conventional boats, this is the Hump speed.
Many factors can change the Hump speed from Hovercraft to another
Hovercraft even if they share the same weight or category, for example; the
distribution of central of gravity, the friction formula between skirt shape
& materials and the ground drag, Also using additional techniques as
geodesic trimming can improve the Hump Speed.
As a rule of the thump, Lower Hump Speed means Reliable Hovercraft, of
course you can get more knowledge by accessing one of our courses.
How the same Hovercraft that flies freely over ice can be used
to break the ice as an Ice Breaker?
-
The secret here is in the total weight per square foot
applied by the Hovercraft on the ground to produce enough displacement air
cushion in respond to the Hovercraft weight, for example; Hovercraft ground
pressure <10lbs/sf can fly easily over fresh snow, the same Hovercraft
with extra weight of fuel and extra air pressure under knees will produce
250lbs/sf which is enough to break this ice then higher weight for thicker
ice, although it will continue hovering because of the pressurized air
creates enough displacement air hole to keep it floating, the same
compressed air hole under the Hovercraft weight is enough to break the ice,
take the fuel off and reduce the weight and the Hovercraft will skim freely
again over the ice without breaking it
If the Hovercraft is that Fantastic, how come it's not that
popular?
-
Well, the Idea of the Hovercraft is the fantastic, but how
you apply it is how it makes it popular, Hovercraft suffered from the high
expectations without the surrounded technology becomes ready, we believe
that the Golden time of the Hovercraft finally come, HoverCollege has the
needed technology that makes the Hovercraft you next garage toy, without you
neighbor complain of noise, and without you looking for a marina slip to
launch it or even to find a place for the trailer.
Can the Hovercraft skim over fresh snow and moving sands?
-
We offered this interesting consulting
many times now, so we though it’s good to offer it in the FAQ, the Answer
is Yes, it possible and secret is in the final applied weight per SF, just
check the minimum weight that will deform the Fresh snow and the moving
sands in your area/country, then adjust the cushion pressure to be 15-20 %
less than this Critical weight, and skim, you’ll be safe, we only charge
for complicated consultations, but this one is on the House.
