PROBLEM TO BE SOLVED: To provide an electro-expulsive de-icing actuator.SOLUTION: An apparatus 100 for removing ice from an object (e.g., in-flight ice removal from the skin of an aircraft) comprises: an actuator assembly 101, 102 that forms an elongated electrically conductive loop. The actuator is mounted in a position enabling the actuator to impact the object to be de-iced in response to movement of the loop that is produced by electric current pulses flowing in opposite directions in two mechanically independent loop subassemblies. The loop subassemblies include multiple electrically conductive elements 101A, 101B, 101C, 102A, 102B, 102C interconnected at ends thereof using elongated flexible connectors 111 to 115 in order to introduce a physical discontinuity that reduces any restriction of relative movement of the subassembly ends. It is thereby possible to realize improved performance and alleviation of fatigue failure as compared with a fixed structure with an encapsulated element.SELECTED DRAWING: Figure 12
【課題】電気除去式除氷アクチュエータを提供することを目的とする。【解決手段】対象物から氷を除去(例えば、飛行中の航空機の外板からの除氷)する装置100は、細長い導電性ループをなすアクチュエータアセンブリ101、102を含む。アクチュエータは、2個の機械的に独立したループサブアセンブリ内で二方向に流れる電流パルスにより発生するループの動作に対応し、除氷対象物に衝撃を与えうる位置に搭載される。サブアセンブリ端部の相対動作の制限を低減する物理的不連続を導入するために、ループサブアセンブリは細長いフレキシブルコネクタ111〜115を用い、端部で相互接続される複数の導電素子101A、101B、101C、102A、102B、102Cを含み、これにより、封止素子をもつ固定された構造と比べ改良された動作および疲労破壊の低減を達成する。【選択図】図12
