摘要:
A gear reduction (48) drives a fan rotor (42) at a speed slower than a fan drive turbine. The turbine section further includes a high pressure turbine (54) driving a high pressure compressor (52). The fan drive turbine and low pressure compressor (44) are connected by a shaft (40). The low pressure turbine, the shaft (40) and the low pressure compressor (44) define a low pressure spool (30). The low pressure spool (30) has a torque at maximum takeoff defined in ft-lbs and also has a low pressure spool power defined in horsepower and at maximum takeoff. A ratio of the low pressure spool torque to the low pressure spool power is defined, and the ratio of the low pressure spool torque to the low pressure spool power is greater than or equal to 0.6 ft-lb/hp (0.0011 Nm/Nm.s -1 ) and less than or equal to 1.2 ft-lb/hp (0.022 Nm/Nm.s -1 ).
