Title The calculation of Secondary ignition engine extended
range rocket ballistic
Abstract
and calculation parameters to optimize the design and achieve the purpose of the
extended range, secondary ignition engine ignition delay extended range is one of the
more incremental application process technology.
This paper analyzes the characteristics of extended-range ballistic missile outside the
establishment exterior ballistic mathematical model to analyze the impact of each
Moroto ballistic characteristics and to determine the optimal trajectory data parameters,
the analysis of the impact of the range trends, in order to achieve the purpose of
improving the rate of growth process .
The current aviation 57mm-1, 2 aviation optimally extended-range rocket design,
analyze the impact of each Moroto extended range of parameters required to calculate

the optimal range of procedures performed by the external ballistic trajectory
simulation, analysis of optimal extended-range plan, not only for the project to
determine the parameter selection and provides a basis, but also in the development of
future projects, and provide some reference.
