Goal‐oriented (GO) methodology is a graphic inductive method mapping the system structure, its function constitute, characteristics, and working principle visually based on decision tree. Recently, the studies on reliability technologies for GO method of complex systems have been gotten a lot of attention by scholars because of the obvious advantages of modeling and analysis power. Indeed, the GO...
HA accomplished with EHA constitutes the dissimilar redundant actuator system driving the control surface together, namely HA/EHA system. The novel actuator structure has greatly improved the overall performance of the aircraft. However, the reliability assessment of HA / EHA system becomes difficult due to the increased complexity. Whether powered by hydraulic or electrical, the components present...
As a key subsystem in aircraft, electro-hydraulic power and actuation system embodies performance and reliability that is crucial to aircraft safety, maneuverability and flight quality. The substantially increased system redundancy and high volume of dissimilar redundancy further complicate the aircraft electro-hydraulic control and actuation system. This paper presents the reliability model based...
