ABSTRACT:
Propellers are provided to drive a vehicle or to bear a vehicle in air. Such propellers have commonly been fixed to wings or fuselages. The fixed locations of the propellers limited the abilities and capabilities of the respective vehicle. The invention now provides arrangements on or to propellers which makes it possible to change the location of the respective propeller relatively to another portion of the vehicle. The change of the location of the propeller in relation to another portion of the vehicle makes it possible to improve the abilities or capabilities of the vehicle. Specifically beneficial effects are obtained by applying the invention to propeller-pairs. Specific relations of locations of propellers to wings or to flow of air in combination with means to pivot portions of the arrangement(s) can lead to better overall efficiencies, speeds, bearing capacities, economy or comfort of the vehicle or of portions thereof.
