摘要： In one embodiment, a nozzle of a gas turbine engine may be provided having a coanda injector and a fluidic injector which operate together to provide for a change in exhaust flow direction. The fluidic injector may be coincident with or downstream of the coanda injector and both may be used in high pressure ratio operations of the nozzle. The fluidic injector may be positioned opposite the coanda injector and, when activated, may provide for a region of separated flow on the same side of the nozzle as the fluidic injector. The coanda injector may provide additional momentum to an exhaust flow flowing through the nozzle and may encourage the flow to stay attached on the coanda injector side of the nozzle.
摘要翻译： 在一个实施例中，可以提供燃气涡轮发动机的喷嘴，其具有共同作用以提供排气流动方向的改变的共用喷油器和流体喷射器。 流体注射器可以与安联注射器重合或下游，并且两者可以在喷嘴的高压比操作中使用。 流体喷射器可以与安联注射器相对定位，并且当被激活时，可以提供与喷射器相同的在喷嘴的相同侧上的分离流动的区域。 大空中注射器可以向流过喷嘴的排气流提供额外的动量，并且可以促使流动保持连接在喷嘴的连线喷射器侧。
