Title: Zoltan L Libertini: Innovator in Gas Turbine Technology

Introduction

Zoltan L Libertini is a prominent inventor based in Stamford, CT (US). He has made significant contributions to the field of gas turbine technology, holding a total of 9 patents. His innovative designs have advanced the efficiency and functionality of turbine engines.

Latest Patents

Among his latest patents is a ceramic nozzle assembly for gas turbine engines. This assembly features ceramic inner and outer shroud rings that are concentrically disposed. The design includes recesses in the outer circumferential surface of the inner shroud ring, with apertures extending through the outer shroud ring in alignment with these recesses. Vanes are integrated through the apertures in the outer shroud ring and engage with the recesses in the inner shroud ring. Additionally, a ceramic outer support ring is utilized to securely retain the vanes, while slots or recesses in both shroud rings prevent rotation of the nozzle within the engine.

Another notable patent is the air and oil cooled bearing package. This innovative design incorporates a combination air and oil cooled seal housing that utilizes trapped stagnant air as an insulator. This combination effectively prevents coking of the oil used as a lubricant for the bearings and seals in the hot section of a turbine engine. Pressurized air is introduced from the compressor into the inner structure support housing through hollow passages, absorbing heat as it travels. The oil circulates within an annular cavity, cooling the seal support structure and ensuring proper lubrication of the seals and bearings that support the turbine rotor stages.
