摘要： A turbofan engine (100) having one or more heat exchangers (192) tied to a power gearbox (142) is provided. The power gearbox (142) mechanically couples a low pressure spool (133) and a fan (100) of the turbofan engine (100). The one or more heat exchangers (192) have a heat exchanger capacity defined by a resultant heat transfer surface area density associated with the one or more heat exchangers (192) multiplied by a heat conductance factor that relates a power gearbox heat load, a fan power consumption function, a fan diameter of the fan (100), and a bypass ratio of the turbofan engine (100). The heat exchanger capacity is between 0.77 and 298.17 for a rotational speed of the low pressure spool (133) between 2,000 and 16,000 revolutions per minute at one hundred percent capacity and a resultant heat transfer surface area density being between 3,000 m 2 /m 3 and 13,000 m 2 /m 3 .

摘要： A turbofan engine (100) having one or more heat exchangers (192, 192B, 192C, 192D) tied to a power gearbox (142) is provided. The power gearbox (142) mechanically couples a low pressure spool (133) and a fan (134) of the turbofan engine (100). The one or more heat exchangers (192, 192B, 192C, 192D)have a heat exchanger capacity (HEC) defined by a rendered heat transfer surface area density ( HTSAD R ) associated with the one or more heat exchangers (192, 192B, 192C, 192D) multiplied by a heat conductance factor (HCF) that relates a power gearbox heat load ( Q CB ), a fan power consumption function ( P FAN ), a fan diameter of the fan (134), and a bypass ratio (BPR) of the turbofan engine (100). The heat exchanger capacity (HEC) is between about 0.77 and 48 for a rotational speed of the low pressure spool (133) between about 2,000 and 16,000 revolutions per minute at one hundred percent capacity and a rendered heat transfer surface area density ( HTSAD R ) being between about 3,000 m 2 /m 3 and 13,000 m 2 /m 3 .
