Abstract: The heater injector of test stand can be modified by using the experience formulation of "machining error of centrifugal injector results in flow rate error", and heating capacity of test stand be increased, and also whether the function of stable section after air flow becoming greater is affected or not and pressure and temperature fields on measuring section be analyzed. The results show that the test range of test stand may be extended and test requirement of ramjet be satisfied.
