Title The Structural Design of Integral Solid Propellant Rocket Ramjets Abstract
According to the design theory of rocket, the paper does the research on the structural design of integral solid propellant rocket ramjets based on meter missile. Through the way of analysis and calculation, the paper finds out the program of propellant structure, material selection, thickness of shell and thermal protection of the gas generator and boost combustor. The paper designs the structure of double nozzle according to the size of boost nozzle which based on calculating internal ballistic. Then the paper test on the properness of boost propellant through calculation missile aerodynamic force. At last, the paper makes out structures and assembly of serial parts with UG. The paper clearly shows the various machining technology and connection methods, and in the end makes out the structure of integral solid propellant rocket ramjets.
