Title Design of rainfall enhancement rocket

Abstract

The rain enhancement rocket is an important military technology to civilian products，which has made great contributions to disaster reduction and disaster prevention in China,and it is the main operation mode of artificial rainfall at the present stage.

According to the requirements of the task book,with rainfall enhancement rockets as research object,conduct the overall，the engine and the parts design of the rain-enhancement rocket,determine the overall view ，the charge , the part structure size and other parameters.After this,the interior and exterior trajectory of rocket were analyzed and calculated.After determining the parameters of charge ， nozzle and combustion chamber,the strength check of the combustion chamber shell and the connecting parts is carried out.The parameters of pressure, thrust ， work time and shoot height can be obtained from the trajectory calculation program.By comparing with the task book design,which can verify that the design meets the requirements.
