Title: Innovations of Bien-Aimé Rakotondrainibe

Introduction

Bien-Aimé Rakotondrainibe is a notable inventor based in Arbonne la Foret, France. He has made significant contributions to the field of turbofan jet engines, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is the "Afterburner arrangement," which relates to a burner ring for turbofan jet engines. This invention features an upstream annular envelope that forms a channel open axially in the downstream direction, along with a manifold for injecting fuel into the channel. The design includes multiple sectors connected together, each equipped with a fuel inlet linked to the fuel injection manifold. Additionally, the upstream annular envelope is positioned within the core flow, and each sector has a connector for the fuel inlet and a ventilation duct that extends through the channel. This duct allows for the emission of bypass air to cool the injection manifold, while a downstream annular envelope protects the manifold itself.

Another significant patent is the "Breakable coupling system for a turbojet fan shaft." This invention involves a rotary shaft arrangement that supports equipment at one end and extends rearwards. The shaft is supported by two bearings, with the first bearing carried by a casing surrounding the shaft. The second bearing is designed with radial clearance in a bore of an annular support secured to the stator structure. This innovative design allows the second bearing to bear against the support in the event of screw rupture, enhancing the reliability of the turbojet fan shaft.
