초록

Each wing of an aircraft carries a set of five outboard spoilers, one inboard spoiler, one inboard aileron and one outboard aileron, together constituting the lateral control surfaces for the aircraft. Each spoiler is positioned by means of a single thread electrohydraulic servoactuator. Each outboard aileron is positioned by means of a one/one fail-operational electrohydraulic servoactuator. Each inboard aileron is positioned by a two/one fail-operational, electrohydraulic servoactuator. The control system is operated by four independent electrical cont...
