The equipment for measuring gas generation rate of fuel-rich propellant was established,and a experimental method was put forward. Pickling asbestos and silica glass fiber cloth were used as filter in the testing equipment to realize reliable separation of gas-phase and condense phase combustion products. And,a reliable method was put forward by verifying the credible separation between gas and solid/liquid. The pressure change in the course of experiment was tested. The results show that the pressure in combustion chamber can be controlled by adjusting sample shape and consumption as well as the back end lid number, and the measurement of gas generation rate of sample under certain pressure can be realized.
