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...

Abstract

The present invention relates to a one-dimensional interior ballistic modeling and performance prediction software system of a solid engine. The system comprises a nozzle type selection module, a charge data import module, a nozzle data input module, an igniter data input module, a user selected data input module and a calculated result display module. The nozzle type selection module is used forselecting the set nozzle type; the charge data import module is used for importing the charge data; the nozzle data input module is used for parameter input of the nozzle; the igniter data input module is used for parameter input of the ignition gas mass flow rate; the user selected data input module is used for parameter input of the working end pressure, the design temperature, and the like; andthe calculated result display module is used for displaying a calculated result. According to the system provided by the present invention, defects of the inaccuracy of the conventional zero-dimensional interior ballistic calculation method, the incomplete consideration of the factors affecting the interior ballistics, and the like are overcome, the simulation precision and the modeling speed ofthe internal ballistic performance of the engine are improved, the design and calculation efficiency of the solid engine is improved, and the product development cycle is shortened.
