Turbofan engine with a low pressure power take-off and high-pressure power-off take

摘要

Provision of the turbofan gas turbine engine having a gear system and power off take of the shaft [challenge] own. Power take-off of one [MEANS FOR SOLVING PROBLEMS] 2 are provided, each is for a high pressure spool and the low pressure spool. Between the high pressure shaft and the low pressure shaft to intersect the core flowpath of a turbofan engine, the power take-off, these extend to the fan frame of a turbofan. Drive gear is provided near the forward end of the high pressure shaft, drive gear and another is provided in the vicinity of the drive gear for the high pressure shaft, the low pressure shaft. Both gears are located in the sump of a gas turbine engine. Power take-off shaft is connected to the drive gear. Is connected to the power take-off shaft, power two devices are arranged in the fan frame. Power device can be a motor or power generator. [Selection Figure Figure 2
