  • Rotation of the ring gear about the respective shaft in relation to the respective rotary element causes all of the gears 70 of that rotary element to be slightly rotated so as to cause the vanes to rotate together between the respective deployed and undeployed positions.
  • Rotation of the ring gear relative to the respective rotary element is accomplished by a plurality of electric motors 74 at three or more circumferentially spaced positions about the core of the rotary element. Suitable gearing couples the electric motors to the ring gears for rotating the ring gear when the electrical motors operate together.

The bearings 84 permit the shafts to remain rotatable relative to one another while additionally supporting the first shaft for longitudinal sliding movement relative to the second shaft.
  • a hydraulic piston cylinder 86 is provided for raising and lowering the main rotary element in relation to the secondary rotary element.
  • the piston cylinder 86 is fixed at a cylinder end on the housing while being rotatably coupled to the first shaft 30 at a cylinder end by suitable bearings 88 so as not to restrict rotation of the first shaft relative to the piston cylinder 86 and the housing to which it is mounted.
  • Control signals for the electric motors 74 of the main rotary element 28 and the secondary rotary element 46 respectively are operable independently of one another to permit vanes of only one of the rotary elements to be deployed at a time if desired. This may be advantageous to the stall characteristics of the aircraft in circumstances where the main rotary element 28 is raised with the vanes undeployed so as to close the openings in the rotary element while the secondary rotary element 46 has vanes which are either partly or wholly deployed so as to permit air to be communicated through the openings in the secondary rotary element 46 housing the vanes therein.

  • the aircraft 10 is permitted to takeoff vertically by engaging the thrust reversers of the jet engines 54 at the sides of the housing or 56 at the rear of the housing and by engaging the mechanical drive mechanism so that thrust from the jet engines 54 drives rotation of the main and secondary rotary elements.
  • the jet engines 54 With the vanes 36 in the deployed position, the jet engines 54 provide sufficient power to the rotary lifting system that the vanes lift the housing 12.
  • the thrust reversers may be undeployed so that sufficient forward speed can be accumulated until the aircraft is above its stall speed.

  • the aircraft 10 enjoys the advantage over other designs of not requiring the use of conventional airports for landing and take-off.
  • Airlines using the aircraft 10 will be able to utilize their own relatively small landing pads adjacent to city centers, and thereby avoid landing fees at regular airports. This would also enable airlines utilizing the aircraft 10 to provide their customers with easy access to and from city centers, and enable their passengers to avoid the usual long drive to airports at the outskirts of the cities being served. This factor would be a distinct marketing advantage.
  • This design also enables airlines to make stops at locations without airports, and enables remote locations to provide for air services by building relatively inexpensive landing pads and to avoid the expense of airports with long runways.

Abstract

L'invention concerne un aéronef (10) comportant un système de portance rotatif (26) présentant des ailettes (36) pouvant se déplacer entre une position déployée dans laquelle les ailettes créent un effet de portance sur l'aéronef (10) lorsqu'elles tournent, et une position rétractée dans laquelle le système de portance rotatif (26) se présente essentiellement sous la forme d'un profil aérodynamique de manière à créer un effet de portance lorsque lesdites ailettes sont entraînées dans un sens d'avancement. Un système d'entraînement en avant (54) sert à créer une poussée normale destinée à entraîner la structure vers l'avant. La forme aérodynamique du système de portance rotatif (26) permet de réduire la taille des ailes (24) d'un aéronef conventionnel, voire de supprimer entièrement les ailes de manière à réduire la traînée créée par des ailes de taille trop importante. Par ailleurs, il n'est pas nécessaire d'augmenter la puissance des moteurs (54) du système d'entraînement en avant pour maintenir l'aéronef à une altitude de croisière normale.
