추진제의 특성변화에 따른 물로켓 비정상추진 이론모델 검증

Water rocket is similar, except that the high temperature heat generated by the chemical reaction of a propellant and the unsteady flow which is pressurized to a pressure change inside the propellant fluid with the passage of time, to rocket propulsion system. The prior water rocket unsteady propulsion theory is divided into unsteady incompressible liquid propulsion and unsteady compressible gas propulsion section. In this paper, conducted a number of experiments in various propellant quantity and pressure conditions, try to verify the unsteady thrust theoretical model. Also we will find out any differences analyzed by comparing the data derived from the same condition.
