The invention provides a shroud type propeller tip turbulent flow blocking device for a duct propeller. The device comprises a propeller blade shroud, which is installed at the blade tip of a propeller blade and forms a closed ring shape, and the propeller blade shroud is embedded in a groove in the corresponding position of the inner surface of a duct shell. According to the shroud type propellertip turbulent flow blocking device for the duct propeller, the shroud type propeller tip turbulent flow blocking device is installed on the duct propeller, so that the duct propeller is low in noise,safe and reliable in operation and large in lifting force.

    本发明提供了一种涵道螺旋桨用围带式桨尖扰流阻拦装置,包括螺旋桨叶围带,所述的螺旋桨叶围带安装在螺旋桨叶的叶尖部位并形成一个闭合的环状,所述的螺旋桨叶围带嵌在涵道外壳内表面对应位置的凹槽内。本发明所述的一种涵道螺旋桨用围带式桨尖扰流阻拦装置,将此装置安装在涵道螺旋桨上,使得涵道螺旋桨噪音低、运行安全可靠、升力大。
