and to driving, pusher or propelled
airscrew tips such as wind turbine blades or for craft such
as boats or submarines using lift or steering in their three-axis
movement, vertical, horizontal and yawing. For existing rates
of efficiency, the invention enables the use of low traction
systems, longer and faster trips while consuming less energy
or while producing more as with wind turbines for example,
the use of greater loads, the increase and approach of aerodrome
or airport transit/landing/take-off traffic more safely. When
used in reverse (active surface/passive surface) on high-speed
land vehicles or racing cars, said device fixed to each wing
tip, produces a result inversely proportional to its speed.
The faster the vehicle runs the less drag it produces and
the more it adheres to the ground.
