Title: The Innovative Contributions of Gilles L Delrieu

Introduction

Gilles L Delrieu is a notable inventor based in Montgeron, France. He has made significant contributions to the field of gas turbine technology, holding a total of three patents. His work focuses on enhancing the efficiency and safety of gas turbine engines.

Latest Patents

One of Delrieu's latest patents is a compressor casing for a gas turbine engine. This invention features an inner casing that is radially adjustable, allowing it to maintain a radial clearance between the casing and rotor during radial expansion and contraction. The design includes an outer casing and a concentrically arranged inner casing, interconnected by a series of radially extending arms. The volume between these casings is sealed to form a chamber, where heated air from a downstream stage of the compressor is directed to contact the exterior surfaces of the hollow radial arms. Additionally, the invention incorporates a system for supplying cooling air to the interior of each radial hollow arm, complete with a regulating device for selective application.

Another significant patent by Delrieu involves a gas turbine engine equipped with a braking device. This device is designed to stop the compressor drive turbine in the event of a shaft break between the turbine and compressor rotors. It features a conical ring attached to the downstream end of the turbine rotor and a structural member of a conical shape at the upstream end of the turbine exhaust casing. This design ensures that the ring will frictionally interlock with the structural member if a shaft break occurs, enhancing the safety of the engine.
