ble. Les brevets des Etats-Unis d'Amérique n 4 055 947, n 4 137 709 et n 4 213 736 décrivent des formes de réalisations antérieures de turbomachines La conception de base d'une turbomachine est définie par la formule D'Euler de la théorie des turbines, qui est une forme des Lois du Mouvement de Newton, appliquée à un fluide traversant un rotor, comme décrit, d'une façon corn. U.S. Patent Nos. 4,055,947, 4,137,709 and 4,213,736 disclose prior art embodiments of turbomachinery. The basic design of a turbomachine is defined by the Euler formula of the theory turbines, which is a form of Newton's Laws of Motion, applied to a fluid passing through a rotor, as described, in a manner
