Title: Innovations of Jean-Philippe E Richard in Gas Turbine Technology.

Introduction

Jean-Philippe E Richard is a notable inventor based in Saint-Medard en Jalles, France. He has made significant contributions to the field of gas turbine technology, particularly with his innovative sealing device for rotor blades.

Latest Patents

Richard holds a patent for a gas turbine engine rotor blading sealing device. This invention allows for real-time adjustments to be made regarding the clearances between the rotor blade tips and the sealing structure. The sealing shroud around the turbine wheel is composed of sectors, each attached to both a monolithic short response time ring and a monolithic long response time ring. Ventilating air from upstream of the turbine wheel is directed onto these rings, causing the sectors to radially expand or contract in accordance with the expansion or contraction of the rotor blade tips during various engine operational modes. A small positive clearance between the sealing sectors and the blade tips is maintained throughout the engine's operational range.
