Latest Patents

One of her latest patents is a labyrinth seal device for gas turbine engines. This invention refers to a labyrinth seal that incorporates a high-pressure compressor with a rotor, a diffuser, and a fixed wall element forming part of the combustion chamber's internal envelope. The seal comprises a stator part mounted on the wall element, which supports an annular wearing part. This wearing part works jointly with a rotor element that has at least one circumferential tooth integral with the compressor rotor to form the labyrinth seal. A key feature of this design is that at least one of the flanges of the attaching means is heavy enough to harmonize the rate of dilatation of the stator part with respect to the rotor element during engine accelerations. Additionally, ventilation orifices are arranged in the wall element, providing a means of controlling the clearance of the labyrinth seal.

Another notable patent is for a gas turbine with a stator shroud in the cavity beneath the combustion chamber. This turbomachine includes a high-pressure compressor with a downstream cone and a diffuser extending downstream by an inner casing. The design features a combustion chamber and a high-pressure turbine whose rotor is connected to the downstream cone of the compressor. The inner diffuser casing and the downstream compressor cone define an under-chamber cavity that is situated downstream from a discharge labyrinth, where cooling air flows downstream. The engine also includes a stator shroud installed under the inner diffuser casing downstream from the discharge labyrinth.
