  MEMOIRE   DESCRPTIF   JOINT la demande de BREVET d'INVENTION   au nom de André WATTEYNE Architecterue Roosendaal à FOREST,   cocernant le PRINCIPE PROPRE à INCLINER vers l'HORIZONTALE l'AXE VERTICAL d'un APPAREIL à VOILURES TOURNANTES. à deux rotors superposés rigidement reliès à   1'axe   qui leur communique le mouvement et tournant en sens inverses.Il est bien entendu que le principe ne s'adresse   qu 'à   un Hélicoptère   n'aya.nt   pas son centre de gravité en-dessous de ses Rotors. en d'autres mots,:Par ce principe,on donne à cet hélicoptère une vitesse d'autant plus grande   qu'il   a son axe vertical plus proche de 1''horizontale. 



  Lorsque, dans un Hélicoptère à deux rotors rigidement reliés à l' axe moteur, co-axiaux, tournant en sens inverses et dont le centre de gravité est situé au-dessu du, rotor supérieur,on augmente pendant le vol l'incidence de l'un ou de l'autre des deux Rotors au-delà de   +   35   degrés.!*Axe   de   1'* appareil   quitte la verticale   qu'il   gardait automatiquement lorsque les deux rotors attaquaient   lais   avec des angles de + 27 à + 28 degrés. 



  L'inclinaison de   l'APPAREIL   EST   AUTOMATIqUE   et proportionnelle à 1%augmentation des angles d'attaque d'un seul rotor seulement au-dessus de cette quantité de 27 à 28 degrés positifs. 



  La Manoeuvre inverse ramène l'appareil automatiquement VERTICAL. 



  Dans les hélicoptèrs actuels dont les Rotors sont montés   d'une     manire   souple et dont le centre do gravité est situé en-dessous des surfaces tournantes (cette deuxième condition nécessitant

 stabilité),l'axe de l'A3rodyne-hélicoptre ne reut s'incliner suf fisemment loin de la verticale et l'appareil par ce fait,ne peut acquérir une grande vitesse.

  DESCRPTIVE MEMORY ATTACHES the patent application in the name of André WATTEYNE Architecterue Roosendaal at FOREST, identifying the PRINCIPLE PROPER to TILT HORIZONTALLY the VERTICAL AXIS of a TURNING BLADE APPLIANCE. with two superimposed rotors rigidly connected to the axis which communicates the movement to them and rotating in opposite directions. It is understood that the principle applies only to a helicopter not having its center of gravity below of its Rotors. in other words,: By this principle, this helicopter is given a speed all the greater as it has its vertical axis closer to the horizontal.



  When, in a helicopter with two rotors rigidly connected to the motor axis, co-axial, rotating in opposite directions and whose center of gravity is located above the upper rotor, the incidence of 'one or the other of the two rotors beyond + 35 degrees.! * 1' axis * aircraft leaves the vertical which it kept automatically when the two rotors attacked the road with angles of + 27 to + 28 degrees .



  The inclination of the DEVICE IS AUTOMATIC and proportional to 1% increase in the angles of attack of a single rotor only above this amount from 27 to 28 positive degrees.



  The reverse operation brings the device automatically VERTICAL.



  In current helicopters whose rotors are mounted in a flexible manner and whose center of gravity is located below the rotating surfaces (this second condition requiring

 <Desc / Clms Page number 2>

 the existence of the first in order to obtain a certain
 EMI2.1
 stability), the axis of the A3rodyne-helicopter cannot tilt sufficiently far from the vertical and the aircraft cannot therefore acquire a high speed.



  This Patent relates, therefore, $ a Helicopter also called Gyroptre, including Engineer Arthur JOUNG (of BELL AIRCRAFT

 Cy) from BUFFALO U.S. À.) 2. Affirms that it would be stable if the center of gravity were above the ROTORS .. (INTERAVIA NQ magazine of July 1947.



    Opinion of Arthur JOUNG confirming the assertions defended by the patent taken in 1924 by the Belgian René Neuteleers. Patent which has since fallen into the public domain.



  The process used by Mr. Neuteleers to tilt 1% axis of the apparatus consisting in moving the center of gravity in the direction of the height, not seeming to us practical for a commercial apparatus,
