A system for supplying pressure of an air pump for a water rocket launch is provided to install a pressure gauge in a pressure supplying unit, thereby visually confirming intensity of the air pressure and operating the apparatus accurately. In a system for supplying pressure of an air pump for a water rocket launch, a pressure supplying unit(0) is combined with an outlet of the air pump(P). The pressure supplying unit is composed of a first air hose(11a), a second air hose(11b), and a third air hose(11c). The first air hose is connected between a pressure room(3) and a connector(12a), the second air hose is connected between the connector and a connector(12b), and the third air hose is connected between the connector and a nozzle(15). A pressure gauge(14) is installed in a center part of the connector for measuring the air pressure inside the air hoses. A length of the second air hose is variable. The third air hose is selected according to the type of the nozzle. |
