Latest Patents

One of Gaurav's latest patents is focused on gas turbine cool-down phase operation methods for controlling turbine clearance by adjusting air flow rate. This application describes a method of operating a gas turbine during its cool-down phase. The gas turbine consists of a compressor, a combustor downstream of the compressor, and a turbine downstream of the combustor, which includes a turbine vane carrier. The method involves feeding a flow of cooling air from the compressor to the turbine vane carrier, measuring the temperature of the cooling air flow, and measuring the temperature of the turbine vane carrier. The flow of cooling air is fed at a first flow rate when the temperature of the turbine vane carrier is lower than that of the cooling air, and at a second flow rate when the temperature of the turbine vane carrier is higher than that of the cooling air, with the first flow rate being higher than the second.

Another significant patent is for a maintenance assembly adaptable within a gas turbine engine. This assembly allows workers to perform maintenance activities within the engine by being arranged within a cavity, generally around a combustor, and accessible from a manhole of the gas turbine engine. The maintenance assembly includes a platform and an inflatable member that is configured to the platform. The inflatable member is in a normal condition when placed outside of the cavity, being deflated, and in a working condition when arranged within the cavity, being inflated to accommodate the shape of the cavity. This design enables workers on the platform to reach predetermined positions within the cavity to perform maintenance activities effectively.
