Definitions

  • This innovation is of the helicopter-airplane, with mechanical properties, like a helicopter, and an airplane.
  • This helicopter is mainly centre of grafity piloted, and while it flies like an airplane, it can use also an airplane's normal fin and horizontal stabilizer.
  • the horizontal stabilizer can to be in during the helicopter flies whitout any pilot, and when it flies like an airplane, take part about it.
  • rotors, engines, and wings are combination set, and to join to the cabin by the longitudinal axis, and these can to do rolling movement by hydraulic cylinder of the cabin.
  • the coaxial shaft pull the pipe round of it and the pipe's end is the collar step bearing, concentricity axle of the pipe, as the engines is same.
  • the wings and the coaxial shaft is connect by the intermediate gear, with this can to choose between the helicopter-or the airplane fly position.
  • the rotor's and wing's gears are same dimensions, they turn always same angle, or when the rotors of the helicopter are straight up, so wings are straiht up too, and when the rotors axles are straight ahead on, also the wings is same direction, as the airplane.
  • the helicopter's mass centre is under of the rotors, while when fly as an airplane, the mass centre and the wings lift up is one moment of the rotation and it counter torque is the rotors' pull and the mainly air resistance of the body, and when this momentarm is longer, so the airplane need smaller power to fly as a helicopter.
  • the moment of the rotation does too, and it balanced by the horizontal stabilizer.
  • the pilot of this helicopter come about centre of the grafity pilot, for example, if want to go front right, do to the rolling movement of the rotor to front and right. Both of these pilot of course happen by the one control stick.
  • the helicopter has four wheels, for it can also to take-off and land as an airplane.
  • the patent numper De 1023327 decision difference is the most, that there are not the coax shaft or both ways rotation rotors, also the engine is dead axle to the propel, and the engine must to turn, when change the fly in the one way or the another, and only innermost of the wings turn, so this cannot be same kind decision, as this patent application of the helicopter-airplane.
  • the picture 1 present the side view of the helicopter-air lane, when it fly as a helicopter , in the broken line there are rotors, wings and the horizontal stabilizer condition, when it fly as an airplane .
  • the picture 2 present how pull of rotors get to transmith to the pipe round of it and in the end of bearing flange and to the frame, and how the rotors get from the same gear rotation the both ways, in the picture can see too, how intermediate gear can to get either the helicopter or the airplane condition during the flight, in the picture also can see, how engines, rotors, and the wings are the join and the bearing by the two bolts to the frame .
  • the picture 3 present front view of the cross cutting of about the picture 2, from cutting line A-A, where can see two engines and about the connecting gears to the rotors, and about the cross cutting of the frame.
  • the construction of the rotors axle in the this picture is cross cutting by B-B in the picture 1
  • Round of the rotor's axles 1 is a pipe for the two parts of frame 20 and 21, by flange 22, in this center of the flange are bearing for enginesl9 and the central gears 7.
  • the engine 19 is connect to the frame 20 and 21, by the bolts 23.
  • the intermediate gear 13 is between frames' 20 and 21, and to the connect to half of the intermediate gear 14.
  • By the bolts 24 is cabin of the helicopter 25 to connect and bearing to the axis of the rotation 16, and the again to the of mentioned above.
  • This helicopter is centre grafity pilot and the rotor rotations is both ways and so nullify the rolling moment, example if flies to ahead, in this way pilot flange of rotors always can to be on the same level, only the rotors' blade angle change, when want to change of power, or when speed change when fly as an airplane.

Abstract

L'invention concerne un aérodyne comportant un rotor du type double, coaxial contrarotatif à deux hélices, et son application à un hélicoptère-avion pour tirer profit des caractéristiques des aérodynes. Lors du vol en mode hélicoptère, le pilotage de l'avion se fait par gravité. Le rotor est entraîné par deux moteurs placés de part et d'autre de l'arbre porte-hélice. Un vérin hydraulique permet la transition, de position verticale en position horizontale, de l'arbre porte-hélice monté pivotant au moyen d'un système d'engrenages. Lors de la transition verticale-horizontale de l'arbre porte-hélice, un engrenage déplace simultanément l'aile. L'ensemble du système moteur-rotor est suspendu pivotant et inclinable grâce à des vérins hydrauliques. L'avion comporte également un stabilisateur horizontal et une dérive.
