Tandem Airfoil Flairboat
A tandem Airfoil Flairboat is a ground-effect vehicle based on the stowage wing principle , designed and developed by Günther W. Jörg since 1963 . The parallel arrangement of two pairs of wings one behind the other (tandem arrangement) in combination with a special fuselage with vertical stabilizer and propeller leads to a stable flight in the ground effect , i.e. H. within the special properties of air close to the ground.
Leaving the ground effect is not intended. The special construction means that a self-stabilizing effect occurs, which guarantees the safe flight of the vehicle close to the ground.
This effect has a particularly good effect over water, so that the special application of the tandem airfoil vehicles as tandem airfoil flair boats (TAF) lies here. A TAF cannot leave the ground effect, but is tied to the presence of the water surface. For this reason, tandem airfoil flair boats are also considered watercraft and are approved and classified as boats.
