Abstract:

The paper gives the general equation for the admittance ratio or response function of burning solid propellant. A single chart based on this equation, has been constructed which simplifies obtaining the admittance from experimental data. The conventional, approximate equation, used in all T-Burner computations, is shown to be a special case of the general equation, valid only at high frequencies. A discussion of the mechanisms responsible for the oscillating frequency being different from the natural frequency is given. It is also shown how by measuring the mean temperatures in the T-Burner these frequencies can be determined and used in the admittance computation. Author
