    Abstract: A gas turbine engine composite blade includes an airfoil having pressure and suction sides extending outwardly in a spanwise direction from a blade root along a span to a blade tip. A core section of the blade including composite quasi-isotropic plies extends spanwise outwardly through the blade. One or more spars including a stack of uni-tape plies having predominately a 0 degree fiber orientation with respect to the span and extending spanwise outwardly through the root and a portion of the airfoil towards the tip. Spars may include pressure and suction side spars sandwiching a chordwise extending portion of the core section in the airfoil and which be located near or along the pressure and suction sides respectively. Chordwise extending portion may be centered about a maximum thickness location of the airfoil. Spars may have height, width, and thickness that avoids flexural airfoil modes.

    Abstract translation: 燃气涡轮发动机复合叶片包括具有压力和吸力侧的翼型件，翼面方向上的叶片根部沿着跨度向叶片顶端向外延伸。 包括复合准各向同性层的叶片的核心部分通过叶片向外延伸。 一个或多个翼梁，其包括相对于跨距具有主要为0度纤维取向的单层帘布层的堆叠，并且沿翼部向外延伸穿过根部，并且一部分翼型朝向尖端。 翼梁可以包括压力和吸力侧翼片，其将翼部的芯部的弦向延伸部分夹在翼型中，并且分别位于压力侧和吸力侧附近或沿其。 弦翼延伸部分可以围绕翼型件的最大厚度位置居中。 翼梁可能具有避免弯曲翼型的高度，宽度和厚度。

    Abstract: A platform apparatus for a propulsion rotor having an annular array of airfoils carried by a rotor disk. The apparatus includes: at least one forward segment comprising an arcuate forward body having a plurality of spaced-apart axially-extending forward fingers, each of the forward fingers bounded by a curved first lateral edge interconnected to a straight second lateral edge by an aft edge, wherein the forward segment defines a flow path surface and an opposed back surface; at least one aft segment comprising an arcuate aft body having a plurality of spaced-apart actually-extending aft fingers, each of the aft fingers bounded by a curved first lateral edge interconnected to a straight second lateral edge by a forward edge, wherein the aft segment defines a flow path surface and an opposed back surface, and wherein the aft edges have a shape complementary to a shape of the forward edges.
