Title: The Innovative Contributions of Bertrand J. Heurtel
Introduction
Bertrand J. Heurtel is a notable inventor based in Vert Saint Denis, France. He has made significant contributions to the field of turbomachinery, holding two patents that showcase his innovative approach to rotor blade fixing arrangements.
Latest Patents
His latest patents include a "Blade fixing arrangement for a turbomachine rotor" and "Rotor blade fixing for turbomachine rotors." The first patent describes a method where each blade of a turbomachine rotor is secured to the drum by upstream and downstream legs on the radially inner side of the blade platform. These legs cooperate with annular beads on the drum's periphery, and a locking plate holds the legs in position. The design ensures that the upstream leg fits into an annular groove in the upstream bead, while the downstream leg features an aperture that receives a tongue from a collar on the downstream bead. The downstream leg also ends in a cylindrical bearing surface that interacts with the drum's surface, incorporating hooks for added security.
The second patent outlines a rotor blade stage formed by sectors secured to a rotor drum through flanges on the blade platform. These flanges cooperate with corresponding flanges on the drum, featuring holes for a cylindrical pin that maintains the assembly's position. Scalloped segments are used to lock the assembly in place, ensuring a robust and reliable rotor structure.
