blowdown limit

名詞

(aviation) The maximum deflection that a control surface is capable of reaching under given flight conditions; past this limit, the aerodynamic forces acting on the control surface exceed the maximum opposing force available from the control surface's actuators.

日本語の意味

航空分野において、与えられた飛行条件下で制御面が達し得る最大の偏向量を指す。これ以上偏向すると、制御面に作用する空力力が、制御面を操作するアクチュエータが発生できる最大の反対力を超えてしまう現象を意味する。

During high-speed maneuvers, the pilot monitored the aileron's blowdown limit to avoid control saturation.

高速機動中、操縦士はエルロンが現在の飛行条件下で到達可能な最大偏向角を監視し、操縦系の飽和を回避した。

(aviation) The maximum deflection that a control surface is capable of reaching under given flight conditions; past this limit, the aerodynamic forces acting on the control surface exceed the maximum opposing force available from the control surface's actuators.

The National Transportation Safety Board determines that the probable cause of the United Airlines flight 585 accident was a loss of control of the airplane resulting from the movement of the rudder surface to its blowdown limit. The rudder surface most likely deflected in a direction opposite to that commanded by the pilots as a result of a jam of the main rudder power control unit servo valve secondary slide to the servo valve housing offset from its neutral position and overtravel of the primary slide.
