As the drawback of high weight

large quantity requirement of propellant

limited launching height and high cost in engine and shell material of existing meteorological rocket

the structure of rocket was designed with fiberglass produced by a specific processing technology as the substitute of steel.SQ-2 double based propellant produced with special wrapping process was utilized to replace the former turning casting propellant.During the process of structure design

the flight dynamic property of overall meteorological rocket was assumed reasonably to simplifying the design and optimum designs of main components were done

then the whole rocket design was fully completed.Pneumatics calculation and full rocket flight experiment were carried out

and the reliability were verified.
