PURPOSE: A liquid rocket injector testing apparatus is provided to precisely analyze a variation of flow rate of a plurality of injectors by feeding compressed nitrogen gas through outputting a feedback signal of a servo control valve based on a variation of pressure supplied into the injector. CONSTITUTION: A liquid rocket injector testing apparatus includes a measuring section(30) for measuring the amount of injected water and injection pressure by injecting water into an injector and a water feeding section(20) for supplying water into the injector of the measuring section(30). A gas supply section(10) supplies predetermined gas pressure into the water feeding section(20) so as to allow water to be supplied into the gas supply section(10). The measuring section(30) is connected to a computer so as to allow users to measure the amount of water and pressure of water injected from the injector.
