Introduction

Sébastien Serge Francis Congratel is a notable inventor based in Moissy Cramayel, France. He has made significant contributions to the field of turbine technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and performance of turbine engines.

Latest Patents

One of Congratel's latest patents is a turbine wheel for a turbine engine, which features a disc carrying blades. Each blade includes an upstream radial wall and a downstream radial wall that extend inwards from the platform of the blade. The design incorporates inter-blade cavities that accommodate sealing and vibration damping members. These members are engineered to obstruct the flow of incoming air into the cavity between adjacent radial walls, thereby improving the turbine's performance.

Another patent by Congratel also pertains to a turbine wheel for a turbine engine. This design includes a disk with blades that have a platform and an impeller connected by a stilt to a root. The roots of the blades are engaged in slots on the disk's periphery, allowing for a circumferential arrangement of the radial walls and platforms. This configuration defines inter-blade cavities that house inter-blade sealing and vibration damping members, which are designed to be elastically prestressed against the cavity walls.
