AbstractPropellant missile engine installed is a pressure for solid propellant missile engine installation of the device. The device used mainly hydraulic drive, a hydraulic pump station is a small pumping stations, power smaller, covers an area of small, compact and by the hydraulic cylinder to achieve a straight line drive, with a special fixture will missile engines Shell is fixed, while ensuring hydraulic cylinder engine with the missile shell of the coaxial meet installation requirements in the hydraulic cylinder piston rod driven by the movement of solid propellant into the shell. In the course of their work, use pressure sensors and displacement sensor monitoring grain at the state campaign to ensure production safety. This single device can be done, simple, do not particularly strong professional knowledge and missile engine capacity of the pressure of the solid propellant missile with pressure to achieve the process automation, eliminating the human, work more efficient, while increasing the production process in the safety factor, truly green design and the people of this design So that the mechanical, electrical, fluid integration, in line with modern design words: missile engine; grain; pressure capacity; hydraulic pump station; hydraulic cylinder
