Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1 Shown is the main interface of the one-dimensional internal ballistic modeling and performance prediction software system for solid motors. This interface is used to set the nozzle type, whether there is a thrust termination mechanism, and import or set the basic calculation data of the charge, nozzle, ignition and other components.

[0029] Nozzle types include conventional nozzles, long tail pipes, beveled nozzles and other types of nozzles.

[0030] In addition, the main interface of the solid engine one-dimensional internal ballistic modeling and performance prediction software system also includes functional modules such as opening / saving internal ballistic files, internal ballistic calculation, exit, printing, and zooming in.

[0031] Such as figure 2 As shown, the charge data import interface. This interface is used t...
