Abstract
In the process of aircraft development, the assessment of handling quality is particularly step for verifying the cockpit control units design whether meets the design requirements or not. If the assess results are not met the design requirements, the design must to be optimized or even redesigned. At present, most of research is mainly related to the design of cockpit control units and simulating and assessment of their maneuverability based on the dynamic model in the normal mode, however, the research on handling quality of cockpit control units in the failure operating mode is seldom. Moreover, override rod linkage form as a new kind of cockpit control units brings plenty of profits such as the weight saved and maintainability improved, however, it causes the failure mode becomes diverse and complicated. Therefore it will increase the difficulty of assessing this kind of cockpit control units. The object of this paper is to do a research on working principle and physical characteristics of cockpit control units of override rod linkage form, through modeling and simulation on its normal operating mode and failure mode, and finally gives an analysis and evaluation for the column force quality of each failure mode. The simulation results reveal the column force quality of each failure mode is acceptable.
