This paper describes the extended work for the methods of analysis of the T-burner experimental data which was published earlier this year. The combustion instability in solid rocket motors is mostly ad-dressed using a T-burner by the measurement of response function for a given solid propellant. The experimental data could be reduced to the required response function by many methods. Six different methods of analyzing the experimental self-excited T-burner data at 1 MPa were presented in the previous work which consisted of Perry’s method, Culick’s method, and an exponential method with different combinations. It was observed that Culick’s method is better when compared to the other methods. However, the recent investigations revealed that Culick’s method has issues when analyzing the response data at higher pressures and for pulsed tests. This paper revisits those methods, compares them with new methods, and finally arrives at a method which is acceptable for any pressure and any test result (self-excited/pulsed). It was observed that the modified Perry method is better for all the different kinds of T-burner data to deduce the combustion response at different pressures and frequencies. The advantages of this method are brought out. This method is working better than Culick’s method and is useful in all the T-burner test data analyses from which the stability prediction of solid rocket motors could be developed. © 2023.
