Title: The Innovations of Marc Stephan

Introduction

Marc Stephan is a notable inventor based in Melun, France. He has made significant contributions to the field of aeronautics, particularly through his innovative designs and patents. With a total of 2 patents, his work reflects a commitment to enhancing the efficiency and functionality of aeronautical equipment.

Latest Patents

One of Marc's latest patents is an elbow bracket for aeronautical equipment. This invention features an elbow bracket designed for cables or pipes, supported by a structure of an aeronautical device. The unique aspect of this design is that a reinforcing rib of the elbowed main plate is not assembled by welding but by tightening, which follows a twisting of end-pieces traversing slots of the main plate. This method allows the outer face of the plate to be trapped against an upper face of oblong slits partially cutting into the end-pieces. As a result, the support is faster to construct and possesses sufficient resistance.

Another significant patent is a device for feeding fuel to a combustion chamber in a turbomachine. This device comprises an annular fuel feed rail that extends around the outer casing of the combustion chamber. It includes a plurality of injectors fixed to the casing, which open into the combustion chamber. The injectors are connected to the rail by fuel transport ducts and support means that are deformable in bending, twisting, and pivoting. This design allows the casing to expand thermally in a radial direction relative to the annular rail while providing rigid support for the rail.
