Answer study questions. Name the four major units of the LM2500 gas turbine module. Describe the EOP procedure used for entering the LM2500 gas turbine module, and what this procedure is designed to accomplish. In this lesson we will cover the LM2500 design and operating characteristics, and discuss how these features affect overall operation of a gas turbine platform. Today's operational gas turbine engines use the open Brayton cycle. .
Atmospheric air provides the working mass. .
The mass is drawn from the atmosphere and compressed. . Heat is added by mixing fuel with the compressed air and igniting the mixture. . Work is extracted by expanding the hot gases through a turbine. . In the combustor section, fuel is added through fuel nozzles and combustion occurs. . A two stage high pressure turbine on the exhaust end of the combustor drives the compressor. .
