Title: Michel R Ayache: Innovator in Gas Turbine Technology
Introduction
Michel R Ayache is a prominent inventor based in Epinay sous Senart, France. He has made significant contributions to the field of gas turbine technology, holding a total of four patents. His work focuses on enhancing the efficiency and performance of aviation turbojets.
Latest Patents
One of his latest inventions is a temperature control device for gas turbines. This device features a portion of the stator known as the turbine shroud, which is situated radially opposite the mobile vanes of a turbine stage. It includes an 'abradable' member supported by a first shell, which is braced by a second shell connected to the turbine casing by a flexible annular wall member. Cooling air inflates the second shell to brace the exterior shell and circulates between the two shells to cool them, as well as the 'abradable' member through impingement. This invention is particularly applicable to aviation turbojets.
Another notable patent is the labyrinth seal, which is mounted between a shaft and the casing of a gas turbine combustion chamber. This seal supports an abradable sealing surface that operates in conjunction with rapidly rotating fins. The cooling of the sealing surface is achieved by an upstream airflow that is parallel to the envelope surface of the fins. The cooling air is drawn from the casing through a conduit connected to an overflow valve tied to the gas turbine load. This invention also finds its application in aviation turbojets.
