LM 6000 - 31041 LM6000 Marine Gas Turbine

The LM6000 is a simple-cycle, two-shaft, high-performance gas turbine that is derived from GE’s CF6-80C2 high bypass turbofan aircraft engine. Taking advantage of the CF6-80C2 low-pressure system’s normal operating speed of 3600 rpm, the LM6000 couples loads directly to the low-pressure turbine shaft. This feature allows the commonality of the CF6-80C2 and the LM6000 to be maintained. The results are low-cost, field-proven parts for the LM6000. The low pressure compressor features independently controlled variable inlet guide vanes and variable stator vanes to modulate airflow, ensuring fast, easy startup/shutdown—even under partial loads. The high pressure compressor is mated to an efficient annular combustor for maximum fuel economy. Incorporation of advanced airflow and cooling technologies helps the LM6000 have unprecedented parts life, and provide reliable and efficient power, low fuel consumption, and low NO

Direct-Drive Means More Useful Power

The LM6000’s power comes directly from the low pressure rotor shaft. There is no free-spinning power turbine, and in 60-cycle applications such as an electric drive ship, no gearbox is required. Loads are coupled directly to the turbine’s cold or hot end. Eliminating the free power turbine allows for greater flexibility in ship design and better use of valuable space.The LM6000 weighs only 17,336 pounds (7,880 kg) which is less thanhalf the weight of other large aeroderivative gas turbines. The entire unit is only 193.5 in long, 85 in wide and 81 in high (4.91 x2.16 x 2.03 m) so you can generate more power in less space. The compact LM6000, with its great environmental and high thermalperformance, is an ideal gas turbine for consideration in ship propulsion systems design when high power output is a requirement.
