Fail-safe control system for hydrofoil craft
专利汇可以提供Fail-safe control system for hydrofoil craft专利检索，专利查询，专利分析的服务。并且A control system for hydrofoil craft of the type which employs dual port control surfaces or flaps and dual starboard control surfaces for controlling motion of the craft about its roll axis. Apparatus is provided for sensing motion about the roll axis of the craft and for producing at least one signal proportional thereto. Three roll channels responsive to a roll signal are provided, one of which controls the starboard outboard control surface, one of which controls the port outboard control surface, and the third of which controls both the port and starboard inboard control flaps. Failure of any one channel will not seriously affect the operation of the craft since failure of both inboard flaps, responsive to one control channel, is equal to failure of either of the outboard flaps which are controlled by separate channels. Preferably, at least two roll gyros are employed, one of which controls a first outboard control surface, the other of which controls a second outboard control surface, and the combined (e.g., mixed) outputs of which control both inboard control surfaces. In the embodiment of the invention shown herein, each control channel also transmits to the control surfaces one or both outputs of dual helm synchros, the arrangement being such that the control surfaces are initially actuated to cause the craft to bank and turn followed by rudder actuation to coordinate the turn.，下面是Fail-safe control system for hydrofoil craft专利的具体信息内容。
