Abstract (en)
[origin: EP3650637A1] A vane stage includes a ringcase (62) extending circumferentially about a center axis (CA) of the vane stage. The ringcase (62) extends completely about the center axis (CA) to form a first ring. An inner shroud (64) extends circumferentially about the center axis (CA) of the vane stage. The inner shroud (64) extends completely about the center axis (CA) to form a second ring positioned radially within the ringcase (62) relative the center axis (CA). A plurality of stationary half vanes (66) extend radially between the ringcase (62) and the inner shroud (64), and are circumferentially spaced about the center axis (CA). The plurality of stationary half vanes (66) are integral with the ringcase (62) and the inner shroud (64).
