  • Rotary machine having an axial abutment that retracts automatically by means of a flexible membrane subjected to the pressure of a fluid
    Patent number: 5232334
    Abstract: The rotary machine includes an automatically-retracting axial abutment system mounted between the rotary shaft of the machine and its case, the abutment system having a displaceable abutment portion that is prevented from rotating, a rotary abutment portion mounted on the displaceable abutment portion by means of a bearing suitable for transmitting axial forces to the displaceable abutment portion, a very stiff flexible device connecting the displaceable abutment portion to the case in such a manner as to enable the displaceable abutment portion to move through a small amplitude in translation along the axis of the rotary shaft, and an axial thrust transmission member for transmitting thrust from the rotary shaft to the rotary abutment portion, the thrust transmission member being shaped to be in contact between the rotary shaft and the displaceable abutment portion when the machine is at rest, and to drive the rotary abutment portion via purely static friction when the machine is rotating and is exerting axi

  • Compact structural assembly for feeding propellants at high pressure to a rocket engine
    Patent number: 5074762
    Abstract: The compact structural assembly comprises a gas generator, and two turbopumps for feeding the combustion chamber of a chamber of a rocket engine with propellants. A main structure which is essentially circularly symmetrical about the axes of rotation of the turbopumps and made of thermostructural composite materials surrounds the turbines and fixes together the body of the gas generator and the pump bodies of the turbopumps. Internal partitioning elements added to the main structure and likewise made of thermo-structural composite materials serve to divide the space inside the main structure into a plurality of intercommunicating cavities allowing hot gases from the gas generator to flow to the turbines, and also serving to collect the outlet gases from the turbines and exhaust them through a common exhaust duct.
