ABSTRACT:
A combustion chamber pressure measuring apparatus comprising a diaphragm pressure bulkhead assembly, pressure transmitting fluid, pressure transducer, and a telemetry section is disclosed for an end burning grain solid propellant rocket. This apparatus eliminates the need for external attachments to the rocket or modifications to the propellant grain and enables fail-safe testing of previously manufactured rockets under actual flight conditions.
