    • Coanda.Effect and lift produced along a surface of an airfoil are increased by- ducting (112) compressed fluid from the engine to the surface of the airfoil. An engine produces exhaust gases that are predominantly directed toward an aft end of the aircraft by a cowling (102) or other structure as an exhaust plume. One or more internal ducts extend (112) from the engine to the surface of the airfoil to thereby transmit a compressed fluid from the engine to the surface in order to suppress flow separation along the surface, thereby causing the engine exhaust flow to remain attached to the surface over a wider span. Such structures and techniques may find particular use in aircraft designed to exploit upper surface blowing (USB) techniques and structures for short takeoff and landing (STOL) performance.
    • 沿着翼面的表面产生的效应和升力通过将发动机的压缩流体(112)增加到翼型件的表面而增加。 发动机产生主要通过整流罩(102)或其它结构作为排气羽流朝向飞行器后端的废气。 一个或多个内部管道从发动机延伸(112)到翼型件的表面,从而将压缩流体从发动机传递到表面,以便抑制沿着表面的流动分离,从而使发动机排气流量保持附着于 表面越宽越宽。 这种结构和技术可以在设计用于利用上表面吹风(USB)技术和用于短起飞和着陆(STOL))性能的结构的飞机中发现。
