Abstract: A blocker door assembly which may be for a cooling system that may be applied to a gas turbine engine includes a plurality of blocker doors circumferentially spaced about an engine axis. Each blocker door is constructed and arranged to move in a circumferential direction to, at least in-part, control air flow through a passage in an adjacent fixture. A sync-ring is concentrically located about the engine axis, disposed in an annular first duct in direct communication with each passage, and engaged to each one of the plurality of blocker doors for simultaneous operation. The sync-ring is aero-dynamically shaped to reduce surrounding airflow resistance.

Abstract translation: 可用于可应用于燃气涡轮发动机的冷却系统的阻塞门组件包括围绕发动机轴线周向隔开的多个阻挡门。 每个阻塞门被构造和布置成沿圆周方向移动至少部分地控制通过相邻固定装置中的通道的气流。 同步环围绕发动机轴线同心地定位，设置在与每个通道直接连通的环形第一管道中，并且与多个阻挡门中的每一个接合以进行同时操作。 同步环是航空动态的，以减少周围的气流阻力。
