Evolution of an Optical Control System for Aircraft Hydraulics 801195
Fly-by-Wire controls are vulnerable to lightning strikes, electromagnetic interference and electromagnetic pulse. Replacing electrical wiring to actuators with optical fiberguides can minimize this vulnerability. Two approaches to the incorporation of optical signal paths in actuation systems are described. One concept requires implementation of “local” electronics while the other seeks to eliminate even this requirement. Both are expected to be flight tested in the near future.
