Abstract: This study evaluates the wear characteristics of flat slide valve material in contact with distributive bush material under varying loading conditions using a pin‐on‐disc apparatus. Given the critical role of hydrodrives in aircraft safety and performance, understanding material wear behavior is essential for enhancing component longevity and operational efficiency. The study assesses key tribological parameters, including the coefficient of friction, wear rate, and mass loss. Experimental results show that at a normal load of 22.5 kg, the material mass loss for linear displacements corresponding to 1975 and 2500 flight hours is 2.25 mg and 3.37 mg, respectively. The maximum coefficient of friction recorded was 0.071 at a normal load of 20 kg. These findings demonstrate that the wear resistance of the tested materials supports the extension of hydrodrive operational life beyond 2500 flight hours, reducing maintenance requirements and enhancing aircraft system reliability. The insights gained from this research provide a foundation for improving the durability of critical aircraft components, ultimately contributing to safer and more efficient aviation systems.
