AirFish Family of Ground
Effect Crafts
The
AirFish ground effect
crafts travel like a ship on water when it departs from the moorings or
berthing site.
After a short run on water, it lifts itself smoothing above the water
to begin an
economical and comfortable ground effect flight on a pneumatic air
cushion.
WigetWorks
has spent
considerable length of time developing the imperative underlying
foundation in
which to research, plan, develop, finance, construct and commercialize
the AirFish
ground effect products.
|
|
|
|
We deliver ground effect crafts to fulfill
the need for a long range operation, with very high efficiencies in
relation to initial capital cost, fuel usage, in-service vessel
maintenance costs and the lowest possible crew training requirements.

Development of AirFish WIG Crafts
The AirFish design was based on the Lippisch's
reverse delta wing concept however with improvements to avoid the
free-flight ability. The development took place from 1979 to 1987 and
in 1987, the prototype
AirFish-1 was built and test flown on Lake Baldeneyon by the
Airfoil Development GmbH (AFD) development partner, an R&D company
called Fischer-Flugmechanik
founded by Mr Hanno Fischer and his
partner Klaus Matjasic.
AirFish–1 cruised on 13 hp at 100 km/h. An unique design feature of the
AirFish ground effect crafts is in its ability to use the kinetic
energy
from cruise flight to jump over obstacles and returned automatically into ground effect. Because it was
inherently stable and could not
cruise above the ground effect level, this and subsequent prototypes
could be flown without a licensed pilot and without complex aircraft
construction and operational requirements.
AirFish-1 had a high
wing span which is disadvantageous for use as a recreational boat. This
led to the
development of the AirFish-2 and the AirFish-3, the recreational ground
effect crafts designed with a lower wing span for the use in regular marinas. Both
AirFish-2 and AirFish-3 had the fuselage of AirFish-1, a new set of
wings
with extremely low aspect ratio and a modified tail.
The AirFish-8 (AF8), an 8-seater ground effect craft was built,
demonstrated and certified in February 2001 at the Markermeer in the
Netherlands.
 WigetWorks Ground
Effect Crafts
WigetWorks has acquired all patents,
industrial property rights and
know-hows from the Airfoil Development GmbH and Fischer
Flugmechanik, covering the complete technology developed in connection
with the design, testing and manufacturing of all AirFish types of WIG
crafts. We will continue the development and
commercial production of WIG crafts on the basis of AirFish
Technology and with the continuing support of the German designers. The
technology acquisition would grant WigetWorks worldwide exclusive
rights and license, with the rights to grant sub-licenses and to sell
and
distribute the AirFish Technology.
 Our
crafts are built as per operation
requirements as nothing less than
"ocean standard" performance. Engine is fully housed and protected,
drive fans are mounted on top of the vessel and well clear of water. We
have incorporated a marine hull that will allow the vessel to safely
stay on task for extended periods in remote regions. Winglets, sponsons
and ailerons are used in order to reduce the wing tip vortex losses and
to give banking and cross wind control to the design, and to allow a
tight radius, banked turn by deliberately rolling the craft using the
wing tip ailerons within the limit of the surface clearance.

AirFish-8 |
 AirFish-8 (AF8)
is a safe,
comfortable,
fast speed (80 - 90 kts) marine craft with low
operating costs and
maintenance needs. All construction is of fiber-reinforced polymer(FRP)
composite,
propulsion is provided by a V8 automobile petrol engine driving two
fixed pitch
airscrews. Auxiliary water drive is fitted for slow speed
waterborne operation and for precise mooring operations. A special
retractable water rudder guaranttees the manoeuvrability.
Standard
fit-out includes regulation safety equipment, Marine VHF radio, global
positioning system, electronics flight instrumentation system, radar
collision avoidance and navigation system, electronic charts, depth sounder,
altimeter and air speed indicators, magnetic heading system, navigation
lights and air-conditioning. For
slipway or ramp use, a retractable undercarriage is available as an
optional extra.

AirFish-3 |
AirFish-3
(AF3) is a
two seater recreational craft
capable of operating in ground effect only. However, it is also
capable of dynamic jumps of up to 4.5 meter high. Normal
operating height is 1 meter. A two cylinder BMW boxer
engine drives a geared six bladed ducted propeller.
For road
transport the AirFish-3 can be
easily towed by trailer,
making it highly portable.

X-113 is capable of
flying in both ground effect and free flight. The
German designer Dr Alexander Martin Lippisch developed the experimental
craft
which has an unique design with a reverse delta wing and a T-tail
arranged outside the ground effect in order to provide natural
stability. An
advantage of the X-113 is its flying ability which enables it to fly
over land and various obstacles and hindrances with a 48 hp engine on
regular fuel. It is exactly as
maneuverable as a regular airplane. It can fly over to another river or
far behind the coast and continue traveling on a lake.
