Creates centrifugal force to propel the ship through the water. Rated at 26,250 braking horse power (BHP). The ship uses 4: 1A and 1B are in Main 1, 2A and 2B are in Main 2
Provides thermal and acoustic protection. Controlled environment for engine. Will withstand 2000 degrees, Fiberglass insulatated. Mounted on 32 resiliant shock mounts
Integrated Electronic Controls (IEC)
Stand alone cabnet. Contains the interface between the MCS and the LM2500.
Lube Oil Storage/Conditioning Assembly (LOSCA)
Filters, cools, removes entrained air and stores the lube oil. It is located on the upper level of the engineroom. Consists of a 40 Gallon storage tank. It is cooled by lube oil from the reduction gear.
Includes air louvers, anti-icing, moisture seperators, silencers, and FOD screens.
Compressor is 16 Stages and has a 16:1 compression ratio
Annular type, houses 30 fuel nozzles and 2 spark ignitors.
High Pressure (HP) Turbine
Two stage. Machanically coupled.
Low Pressure (LP) Turbine
Aerodynamically coupled. Each blade is shrouded to prevent inter-stage air loss.
High speed flexible coupling shaft
links LP turbine to the Main reduction Gear (MRG)
Enclosure Cooling system
Air fan assembly for the modules.
Fire Detection and Extinguishing system
Ultra Violet sensors to detect fire inside the module.
Describe the purpose of the Main Lube Oil (L/O) system
Designed to deliver clean filtered lube oil, at the proper temperature (90-95 Deg F), and the proper pressure
Gas Turbine L/O system
Cools the Turbine oil via a cooler/heat exchanger at the LOSSCA
Main Reduction Gear (MRG)
The lube oil is pumped via 1 attached pump and 2 electric pumps (used to maintain pressure) to 30 bearings (4 thrust bearings, and 26 Journal bearings)
Main thrust bearing
Lubricated by the main L/O system, oil is then returned to the MRG Sump.
