Title: Innovations of Thierry Henri Tassin
Introduction
Thierry Henri Tassin is a notable inventor based in Brunoy, France. He has made significant contributions to the field of engineering, particularly in turbine technology. With a total of two patents to his name, Tassin's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Tassin's latest patents is a turbine vane cooling system. This system utilizes three internal cooling cavities separated by two radial walls. The upstream cavity employs a helical ramp and is fed through an intake at the vane root. The middle cavity is also fed at the vane root and features a compartmented, multi-perforated lining. Air is exhausted from each compartment through impact orifices, entering the succeeding compartment through slots before being finally exhausted through a vane-head orifice. Additionally, the vane side walls opposite the downstream cavity have double skins with bridging elements, allowing air to circulate centrifugally.
Another significant patent is a sealing device designed for rotary machines. This device ensures effective sealing between a rotor and fixed blade stages. Blade edges are connected by rings that carry circular seals in slots, with springs forcing the seals towards the transverse faces of the rotor's reinforcements. This design achieves a turbulence-free gas flow due to the total seal provided by the seals.
Career Highlights
Throughout his career, Tassin has worked with prominent companies such as the Société Nationale d'Étude et de Construction de Moteurs d'Aviation, commonly known as Snecma. His experience in these organizations has allowed him to refine his skills and contribute to various innovative projects.
