01/29/06 - Manta Ground Effect Aerofoil as possible Land Speeder
(Add a propulsion unit and we have a novel new transport method. - JWD)
7 foot 8 inches long by 6 foot wide. It lifts 90 kg at 40 kph [21+ mph
roughly] that's a seventy kilogram person [11 stone] (154lbs.), ask any
aircraft engineer or pilot, they will tell you an airfoil cannot lift
that much weight at that low a speed.
The picture is from a video capture. This is something new with quite a
bit of military capability and potential horse power. Bingo starwars
speeder bike. By the way it works!
The MANTA Ground Effect Aerofoil is a manta shaped wing designed to fly
in ground effect, configured as shown in the accompanying illustrations.
A 50 to 75 foot towline would attach the aerofoil to the tow craft with
a quick release. The aerofoil will plane on its center float at 10 to 15
mph and become airborne at 20 to 30 mph.
With a wingspan of approximately 10 feet, the aerofoil will reach a
height of 1 to 3 feet above the waters surface. To use the MANTA G.E.A.,
a person would lie on the upper central body of the aerofoil and grasp
the handrails; the rider would control the aerofoil by shifting his/her
weight.
Should any problem arise, the rider would only have to release the
towline or let go and slide safely into the water. Design Parameters
