    • A composite gas turbine engine structure includes a retention ring with airfoils mounted on, integral with, and extending radially away from retention ring. Retention ring includes annular composite plies (57), a circumferentially segmented airfoil ring including airfoil ring segments disposed around one of outer and inner circumferences of retention ring. Airfoil ring segments include annular bases and radially extending clockwise (60) and counter-clockwise (62) airfoil segments at clockwise (64) and counter-clockwise (66) ends of annular base. Composite airfoils include circumferentially adjacent ones of the clockwise and counter-clockwise airfoil segments. A flowpath shell (68) circumferentially disposed around segmented airfoil ring traps annular bases between flowpath shell and retention ring. Composite airfoils airfoils extend through slots (83) in flowpath shell. Plies may be wrapped in a single spiral made from a continuous composite tape. Slots may be circumferentially angled. Circumferentially adjacent ones of clockwise and counter" clockwise airfoil segments may be stitched together.
    • 复合燃气涡轮发动机结构包括具有与保持环安装在一体并与径向远离保持环的翼型的保持环。 保持环包括环形复合层(57),周向分段的翼型环,包括围绕保持环的外周和内周中的一个周围设置的翼型环段。 翼型环段包括环形基座和径向延伸的环形基座的顺时针(64)和逆时针(66)端的顺时针(60)和逆时针(62)翼型段。 复合翼型件包括沿周向相邻的顺时针和逆时针翼型段。 周向设置在分段翼型环周围的流路外壳(68)在流路壳和保持环之间捕获环形基座。 复合翼型件翼型件通过流道外壳中的槽(83)延伸。 层可以包裹在由连续的复合胶带制成的单个螺旋。 槽可以是周向成角度的。 顺时针和反向“顺时针”翼形段的周向相邻可以缝合在一起。
