The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine. As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships . [ 1 ]
Dry low emission (abbreviation DLE) is a technology that reduces NOx emissions that exhausts out of gas fired turbines. [1] [2] [3] [4]The amount of NOx produced depends on the combustion temperature. [2]
An LM2500 gas turbine on USS Ford. The first U.S. gas-turbine powered ship was the U.S. Coast Guard's Point Thatcher, a cutter commissioned in 1961 that was powered by two 750 kW (1,000 shp) turbines utilizing controllable-pitch propellers. [95]
The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation.Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners.
The General Electric LM6000 is a turboshaft aeroderivative gas turbine engine. The LM6000 is derived from the CF6-80C2 aircraft turbofan.It has additions and modifications designed to make it more suitable for marine propulsion, industrial power generation, and marine power generation use.
The TF39 was the first high-power, high-bypass jet engine developed. The TF39 was further developed into the CF6 series of engines, and formed the basis of the LM2500 and LM6000 marine and industrial gas turbine. On September 7, 2017, the last active C-5A powered with TF39 engines made its final flight to Davis-Monthan Air Force Base for ...
1 × General Electric LM2500+G4 gas turbine [5] 2 × electric propulsion motors: INDAR 2 x 3.4 MW; 4 × ship service diesel generators Rolls-Royce MTU 20V 4000 M53B engine 3000 kW for a total output of 12 MW; Reduction gears by Philadelphia Gears [6] 2 x fixed-pitch propellers
The four LM2500 gas turbines of the class are most efficient at high speeds; an electric motor was to be attached to the main reduction gear to turn the drive shaft and propel the ship at speeds under 13 knots (24 km/h), such as during BMD or maritime security operations.
