Latest Patents

Paprotna holds a patent for a "System for actively controlling compressor clearances." This invention relates to a system and method for actively managing compressor clearances in a turbine engine. The system utilizes a thermal fluid that is passed in heat exchanging relation through a compressor vane carrier. During specific operational conditions, such as hot restart or spin cool, it is beneficial to heat the vane carrier to either enlarge or prevent a decrease in compressor clearances. In these scenarios, a heated thermal fluid can be provided by reclaiming residual exhaust energy from a heat recovery steam generator. Conversely, when improved performance is desired, the vane carrier can be cooled to minimize compressor clearances. The cooled thermal fluid can be sourced from bleed air, water-cooled high-pressure bleed air, or feed water from the bottoming cycle in a combined cycle engine.
