Abstract: A turbomachine blade having features arranged to initiate bending of the leading edge towards the pressure surface upon impact of a foreign object on the leading edge. The features may be features weaker than the material of the leading edge located on the pressure surface side of a mid-thickness line. By causing the leading edge to bend towards the pressure surface on impact the volume of the foreign object, typically a bird, that passes over the suction surface is reduced.

Abstract: A process for manufacturing a layered composite component includes introducing a plurality of micro cracks into a predetermined region of the component in order to provide an increase in strength of the component at certain critical regions of high loading within the component. The micro cracks may be introduced using mechanical means, a pre conditioning load, or by manipulation of process parameters, material properties or stacking sequences.

Abstract: A blade for a turbine engine made by the diffusion-bonding/superplastic-forming (DB/SPF) process has a hollow skin made of front and back panels 1, 3 and internal reinforcement in the form of webs 5 extending between the two faces or panels at an angle to the plane of the blade. The cavities are filled with viscoelastic damping filler 7. In order to allow the blade to deform more easily so that the filler can take up the strain, the webs are pre-buckled so as to compress at least some of the webs. When the blade is deformed, the webs straighten or buckle further, applying a deformation to the filler as they do so and thus dissipating energy. The blade is thus well reinforced against impact but still capable of damping vibrations.
Abstract translation: 用于通过扩散粘结/超塑性成形(DB / SPF)工艺制造的涡轮发动机的叶片具有由前面板和后面板1,3制成的中空皮,以及在两个面之间延伸的腹板5形式的内部加强件, 面板与叶片的平面成一定角度。 空腔填充有粘弹性阻尼填料7.为了允许叶片变得更容易变形,使得填料可以承受应变,网状物被预先弯曲,以便压缩至少一些网。 当叶片变形时,织物进一步拉直或弯曲,因此在填充物上施加变形并因此耗散能量。 因此,刀片可以很好地抵抗冲击,但仍然能够阻尼振动。
