Beschreibung
Zusammenfassung:	A gas turbine engine includes a compressor section and a turbine section. The turbine section includes a drive turbine and is located downstream of the compressor section. The gas turbine engine alsoincludes a fan mechanically coupled to and rotatable with the drive turbine such that the fan is rotatable by the drive turbine at the same rotational speed as the drive turbine, the fan defining a fan pressure ratio and including a plurality of fan blades, each fan blade defining a fan tip speed. During operation of the gas turbine engine at a rated speed, the fan pressure ratio of the fan is less than 1.5 and the fan tip speed of each of the fan blades is greater than 1,250 feet per second. 种燃气涡轮发动机，其包括压缩机部段和涡轮部段。涡轮部段包括驱动涡轮并且位于压缩机部段下游。燃气涡轮发动机还包括风扇，所述风扇机械地联接到驱动涡轮并能够与驱动涡轮起旋转，使得风扇能够通过驱动涡轮以与驱动涡轮相同的旋转速度旋转，风扇限定风扇压力比并且包括多个风扇叶片，每个风扇叶片限定风扇末端速度。在所述燃气涡轮发动机以额定速度操作期间，所述风扇的风扇压力比小于1.5，并且每个风扇叶片的风扇末端速度大于1，250英尺/秒。
