Zusammenfassung:To provide flow control devices for inlet flow control which overcome constraints of prior art solutions and provide improved performance.SOLUTION: A flow control system on an aircraft engine nacelle incorporates a plurality of flow control devices each having a body. A second plurality of actuators is coupled to the body of an associated one of the flow control devices. The actuator rotates the body about a leading edge of an inlet of a nacelle from a retracted position to an extended position.SELECTED DRAWING: Figure 2C 【課題】従来技術の解決策の制約を克服するとともに改善された性能を提供する、入口流れ制御のための流れ制御装置を提供する。【解決手段】航空機エンジンナセルにおける流れ制御システムは、本体を各々有する複数の流れ制御装置を組み込んでいる。第２の複数のアクチュエータは、流れ制御装置のうちの関連する１つの流れ制御装置の本体に結合される。アクチュエータは、ナセルの入口の前縁部を中心に格納位置から伸展位置に本体を回転させる。【選択図】図２Ｃ
