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.
A CODLAG system employs electric motors which are connected to the propeller shafts (usually 2). The motors are powered by diesel generators.For higher speeds, a gas turbine powers the shafts via a cross-connecting gearbox; for cruise speed, the drive train of the turbine is disengaged with clutches.
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]
The shaft power from each can either go directly to the propeller, pump jet or other mechanism, or it goes through some form of transmission; mechanical, electrical or hydraulic. In the 1800s, steam was one of the main power sources for marine propulsion.
A primary shaft carries the compressor and its turbine which, together with a combustor, is called a Gas Generator. A separately spinning power-turbine is usually used to drive the rotor on helicopters. Allowing the gas generator and power turbine/rotor to spin at their own speeds allows more flexibility in their design.
Another way to combine the two types of engines is to connect them to generators and drive the propellers electrically as in a diesel-electric. See Combined diesel–electric and gas (CODLAG) and Integrated Electric Propulsion (IEP). This also permits propeller pods, with the propulsion motors being located inside the pods.
Current [when?] marine Opposed-Piston applications include use as main propulsion engines and service generators. The USCG Hamilton -class cutters use the 38 8-1/8 engine in a CODOG arrangement, where the diesel engine provides cruise propulsion, and a gas-turbine provides propulsion where high speeds are required.
The General Electric LM1600 is an industrial and marine gas turbine produced by GE Aviation. The LM1600 is a derivative of the General Electric F404 aircraft engine series. [ 1 ] [ 2 ] The LM1600 delivers 20,000 shaft horsepower (shp) (14,920 kW) with a thermal efficiency of 37 percent at ISO conditions .
