CFM56 ENGINES (CFM56-7) 737-600/700/800/900 AIRCRAFT MAINTENANCE MANUAL General The CFM56-7 is a high bypass, dual rotor, axial flow turbofan engine. The engine fan diameter is 61 inches (1.55 meters). The bare engine weight is 5257 pounds (2385 kilograms). The engine has these sections: * Fan and booster * High pressure compressor (HPC) * Combustor * High pressure turbine (HPT) * Low pressure turbine (LPT) * Accessory drive. The fan and booster rotor and the LPT rotor are on the same low pressure shaft (N1). The HPC rotor and the HPT rotor are on the same high pressure shaft (N2). Fan and Booster The fan and booster is a four-stage compressor. The fan increases the speed of the air. A splitter fairing divides the air into these two air flows: * Primary * Secondary. The primary air flow goes into the core of the engine. The booster increases the pressure of this air and sends it to the HPC. The secondary air flow goes in the fan duct. It supplies approximately 80 percent of the thrust during take-off. High Pressure Compressor (HPC) The HPC is a nine-stage compressor. It increases the pressure of the air from the LPC and sends it to the combustor. The HPC also supplies bleed air for the aircraft pneumatic system and the engine air system. Combustor The combustor mixes air from the compressors and fuel from the fuel nozzles. This mixture of air and fuel burns in the combustion chamber to make hot gases. The hot gases go to the HPT. www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：ENGINE
