The report deals with the continued investigation of the reflected- pulse method for measuring the normal acoustic admittance of burning propellant surfaces see AD-609 886. Although the multi-line recording system is now operational, the noise level which it introduces into the signal is probably too high in view of the accuracy required for the admittance measurements. A brief discussion of current instrumentation problems is given. Progress was made in organizing some of the theoretical results obtained in the course of this contract.
