Patents by Inventor Jean-Francois Gerard Jacques Cortequisse

Jean-Francois Gerard Jacques Cortequisse has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8157519
    Abstract: A system for connecting two ferrules of an axial compressor case. A ferrule includes a female flange, while the other ferrule includes a male flange. Both the female flange as well as the male flange are substantially annular and include a proximal face intended to be integral with the ferrule, and a distal face. The male flange is intended to be introduced into a space bound by an axial extension of the female flange. The system further includes a trim intended to be introduced behind the male flange into the space and clamped between the proximal face of the male flange and a surface of the extension substantially opposite in order to space them apart and thus clamp the distal faces of both flanges one against the other.

  • Patent number: 8133011
    Abstract: The invention concerns a novel type of turbomachine. The stator of the turbomachine comprises a plurality of profiled members forming stiffeners arranged on the blade stage. The profiled members are distributed uniformly at periphery of the blade stage and individually between two consecutive blades. The stiffeners are fixed to the internal and external ferrules of the stator in order to uniformly increase the axial and radial stiffness of the stator in normal operation of the turbomachine and to allow the internal ferrules to have a limited displacement during the normal functioning of the turbomachine. This makes it possible to reduce the axial sizing of the turbomachine, and consequently its mass.
