| description | The invention relates to durable riblets for engine environment. An airfoil of a propulsion device having a first riblet laminate with a first adhesive layer on at least a first portion of the airfoil surface and a first riblet array sheet disposed on at least a portion of the first adhesive layer. The first riblet array sheet defines a first plurality of contiguous geometric features having rigid peaks and valleys extending in a first rib direction. The first plurality of contiguous geometric features define a total width to total height ratio W:H of about 1:1 to about 2.5:1 with a maximum total height of about 0.65 mm or less. A second riblet array laminate is also disclosed in an embodiment.
本发明涉及用于发动机环境的耐用凸肋。具体而言，种推进装置的翼型件(90)具有第凸肋叠层(136)，其具有在翼型件表面(92)的至少第部分上的第粘合层(156)以及设置在第粘合层(156)的至少部分上的第凸肋阵列板(130)。第凸肋阵列板(130)限定第多个连续几何特征(110)，其具有在第肋方向上延伸的刚性的峰部(146)和谷部(148)。第多个连续几何特征(110)限定带有大约0.65mm或更小的最大总高度的大约1:1到大约2.5:1的总宽度与总高度比W:H。实施例中还公开了第二凸肋阵列叠层(132)。 |
