Design and verification of aircraft electro-hydraulic servo nose wheel steering system

Based on the control/monitoring architecture, a nose wheel steering system is designed, This paper introduces the steering system in the aspects of composition and operating principle, critical techniques and system validation results. Using results indicate that the system has complete functions, steering process is smooth, power steering angle can meet the requirements of runway width. The system has high reliability and good maintainability. Suggestions are given for consideration in system design.
