Abstract


To maintain and expand our space launch market in the world space launch market status before formally put into use in the generation of carrier rockets, the Long March series of carrier rockets, keep up with the pace of World Space Vehicles, is absolutely necessary to improve and perfect and very meaningful . The premise without reducing reliability and low cost, solid strap is a better solution. \lower launch costs, and to provide users with a good launch services. Through 20 years of technology development, China's launch vehicle liquid propelled bundled has made considerable progress, but still in the blank in the area of ??solid booster rocket. With the continuous development of China's solid-fuel rocket technology, the reliability of solid rocket continuously improve, the cost has also been reduced, coupled with the unique use of solid rocket simple maintenance, simple supporting projects, the use of better performance characteristics has been basically have a as booster rockets conditions. In this paper, a model for the background, were demonstrated after a solid boost overall design, with emphasis on the structure and layout, and performance analysis, the separation of design and stability analysis. Structural layout design, due to the restrictions on the length of the solid rocket through the analysis of the advantages and disadvantages of the different vertical connection, determine a reasonable structure layout program, has a simple structure, easy to \flight in centroid calculations to determine the solid booster rocket engine nozzle angle. Performance analysis, bundled number of adjustment, ballistic simulation, active duty rocket performance can be greatly improved, the formation of a new rocket series has a larger carrying capacity coverage. Longer than by adjusting the level between the solid boosters performance parameters can further improve the carrying capacity of the rocket to reach the level of competence of the CZ-2E rocket. Booster separation system is the key to the launch vehicle system, its success will be directly related to the success or failure of the flight of the rocket booster separation system design must ensure that the boosters are able to achieve safe separation under various conditions. An important component in the separation system on the booster separation power transmission in the form, connection to unlock the device, the power plant and the separation timing analysis program contrast, the design is suitable for solid booster separation system solutions and separation system program and boosters quality characteristics the initial booster separation dynamics simulation to verify the separation system design reasonable. Stability analysis, we selected the state bundled with four solid boosters derived its attitude dynamics mathematical model to analyze the role of external forces on the elastic rocket body and external torque and the corresponding generalized force to write the equations of motion. Digital simulation results through the swing angle of the attitude angle and the engine of the rocket body seen the rocket during flight attitude angles larger anti-jamming capability, but also have a certain stability margin. Calculated by the analysis, the use of existing proven technology and existing rocket module, a series of carrier rockets, the formation of solid strap-on technology is feasible, with a carrying capacity coverage task adaptable, suitable to launch a variety of orbit satellites multipurpose series of carrier rockets. The same time, due to the extensive use of technology has been flight test validation, a short development cycle and high reliability.
