context_page_description: The General Electric CF6, US military designation F103, 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 basic engine core also powers the LM2500, LM5000, and LM6000 marine and power generation turboshafts. It is gradually being replaced by the newer GEnx family.
context_section_description: The CF6-6 was a development of the military TF39. It was first used on the McDonnell Douglas DC-10-10.
  This initial version of the CF6 has a single-stage fan with one core booster stage, driven by a 5-stage LP (low pressure) turbine, turbocharging a 16-stage HP (high pressure) axial compressor driven by a 2-stage HP turbine; the combustor is annular; separate exhaust nozzles are used for the fan and core airflows. The 86.4-in (2.19-m) diameter fan generates an airflow of 1,300 lb/s (590 kg/s), resulting in a relatively high bypass ratio of 5.72. The overall pressure ratio of the compression system is 24.3. At maximum take-off power, the engine develops a static thrust of 41,500 lb (185.05 kN).
