By consideration of the combustion characteristics of the fuelrich propellant at low pressure,the various techniques to measure the combustion properties of the fuelrich propellant,such as, the strand burner method,thermocouple method,ultrasonic method,firing test and highspeed photography method are evaluated. The difference between the recorded pressure and absolute pressure should be noticed in the low pressure experiment data process as well as the selection of the burningrate and pressure correlations.
