Title
(EN) TURBINES UTILIZING JET PROPULSION FOR ROTATION
(FR) TURBINES UTILISANT LA PROPULSION PAR REACTION POUR LEUR ROTATION
Abstract
(EN)
A turbine includes a rotatable vessel and at least one outlet for discharging pressurized working fluid from the rotatable vessel to a lower pressure area to produce jet propulsion for rotating the rotatable vessel. The turbine may also include a shaft having a fluid passage extending through at least a portion thereof for delivering a pressurized working fluid through the shaft to the rotatable vessel. The turbine may further include a ring positioned generally around the vessel within the lower pressure area such that pressurized working fluid discharged from the vessel will contact the ring and rotate the ring in a direction generally opposite to a direction of rotation of the vessel.
(FR)
L'invention concerne un turbine comprenant une cuve rotative et au moins un orifice d'évacuation pour décharger le fluide de travail sous pression de la cuve rotative vers une zone de pression plus basse de manière à produire une propulsion par réaction permettant la rotation de la cuve rotative. La turbine peut également comprendre une tige présentant un passage fluidique qui s'étend au moins sur une partie de celle-ci afin de fournir un fluide de travail sous pression qui traverse la tige jusqu'à la cuve rotative. La turbine peut également comprendre un anneau placé généralement autour de la cuve dans la zone de pression plus basse, de telle sorte que le fluide de travail sous pression évacué de la cuve entre en contact avec cet anneau et le fasse pivoter dans un sens généralement opposé au sens de rotation de la cuve.
