Flight control iron bird based on passive electric-hydraulic servo loading system

摘要

Purpose - The purpose of this paper is to develop a novel type of full-size flight control iron bird based on a passive electronic hydraulic servo loading system. Design/methodology/approach - On the basis of mathematical modeling of passive loading system math model, the detailed design process of the flight control iron bird is presented. Subsequently, the system digital simulation and physical verification are also given. Findings - Experimental results show that the proposed approach can reduce the redundant forces and improve the system dynamic and force-tracking accuracy. Practical implications - This newly-developed flight control iron bird system has been successfully applied in the flight control system design of some fighters. Originality/value - The proposed approach for flight control iron bird is new and significant for the design of fighter flight control systems.
