In order to meet the needs of future missiles for lightweight and miniaturization of the steering nacelle,a design scheme of hydraulic energy system for missiles was proposed.Hydraulic energy integration technology was adopted,which integrated the core of independent hydraulic components into an integrated energy.Under the premise of ensuring technical performance,it can also achieve the goal of lightweight and miniaturization of hydraulic energy systems.The sealing designs of hydraulic energy distribution plate,piston adjustment structure,and piston sliding shoe group were optimized to reduce hydraulic leakage and improve volumetric efficiency.The simulation and test results show that the highly integrated hydraulic energy design realizes the lightweight and miniaturization of the mis⁃sile hydraulic energy,the leakage of the hydraulic pump is reduced effectively,which has the characteristics of high efficiency,small ze⁃ro flow input torque,and low demand for the missile power supply.
