The invention provides a ductless thrust generating system for an aircraft. The aircraft includes a fuselage, a wing connected to and extending outwardly from the fuselage, and an engine mounted to the wing. The engine includes a turbine defining a centerline axis, a fan, and an exhaust section having an outlet nozzle. The turbine defines a centerline axis. A fan is connected to the turbine and disposed upstream of the turbine. The fan is arranged to rotate about the centerline axis. During engine operation, an exhaust flow is discharged from an outlet nozzle of the exhaust section. The exhaust flow defines an average flow direction in a downstream direction of the exhaust section. The average flow direction defines a first angle with a centerline axis of the turbine greater than zero such that the centerline axis is oriented downward in a vertical direction relative to the average flow direction of the exhaust flow.
本发明提供一种用于飞行器的无导管推力产生系统,该飞行器包括机身、连接到机身并从机身向外延伸的机翼,以及安装到机翼的发动机。该发动机包括限定中心线轴线的涡轮机、风扇和具有出口喷嘴的排气区段。涡轮机限定中心线轴线。风扇连接到涡轮机并设置在涡轮机的上游。风扇设置为围绕中心线轴线旋转。在发动机操作期间,排气流从排气区段的出口喷嘴排出。排气流限定在排气区段的下游方向上的平均流动方向。平均流动方向与涡轮机的中心线轴线限定大于零的第一角度,使得中心线轴线相对于排气流的平均流动方向沿着竖直方向向下定向。
