The invention relates to a fan air inlet device and an airplane. The fan air inlet device comprises a device inlet, a device outlet and an air inlet pipeline located between the device inlet and the device outlet, the device inlet is rectangular, the device outlet is round or oval, and therefore the flowing section of the air inlet pipeline is gradually transited from the rectangle to the round or the oval. The fan air inlet device further comprises a first rib, a second rib, a third rib and a fourth rib which are arranged at the four corners of the inner side of the air inlet pipeline respectively, the first rib and the second rib are located on the upper portion of the air inlet pipeline, and the third rib and the fourth rib are located on the lower portion of the air inlet pipeline. The third rib and the fourth rib extend from the device inlet to the device outlet, and the first rib and the second rib extend from the basically middle length position of the upper portion of the inner side of the air inlet pipeline to the device outlet.

    本发明涉及风扇进气入口装置及飞机。该风扇进气入口装置包括装置入口、装置出口、以及位于装置入口和装置出口之间的进气入口管道,装置入口呈矩形,装置出口呈圆形或椭圆形,因此进气入口管道的流向截面从矩形逐渐过渡至圆形或椭圆形,风扇进气入口装置还包括分别布置在进气入口管道的内侧四个角部处的第一肋条、第二肋条、第三肋条和第四肋条,其中,第一肋条和第二肋条位于进气入口管道的上部,第三肋条和第四肋条位于进气入口管道的下部,第三肋条和第四肋条从装置入口一直延伸至装置出口,第一肋条和第二肋条从进气入口管道的内侧上部的基本中间长度位置延伸至装置出口。
