Pressure-Measuring Instrumentation for Combustion Stability Studies

摘要

The operation of the pressure-measuring system employed in the solid-propellant combustion stability study being pursued under the present contract is described, and the limitations of the system are pointed out. Although this system represents a considerable advancement over conventional pressure-measuring instruments, it is recommended that future investigations of combustion stability employ the still further improved pressure-sensing elements and tape recording system which have recently become available, as well as refined methods of determining the dynamic response of the pickups.
