The entire system has a large number of components,complex layout,and high pipeline leakage failure rate,which limits the improvement of reliability and maintainability of the aircraft braking system.In recent years,a self-powered brake system for aircraft has been proposed.The modular"self-powered brake device"is installed near the wheel to recover the rotational energy of the wheel when landing,and convert it into hydraulic energy for brake action.In order to improve the reliability and safety of the UAV brake sys-tem,a dedicated energy harvesting mechanism using gear sets was proposed.A compact dedicated energy harvesting mechanism for the self-powered brake system was designed,and a highly reliable and integrated prototype of the self-powered brake system was developed.Environmental tests,inertial platform tests,and in-stallation sliding tests were completed,achieving self-powered brake and greatly improving the reliability,maintainability and supportability of braking system.
