International Telemetering Conference Proceedings / October 28-31, 1985 / Riviera Hotel, Las Vegas, Nevada === Previous solid rocket motor instrumentation was inadequate to correlate motor performance with analysis. This is particularly obvious when flight failures occur. The addition of instrumentation, both externally and internally, to the rocket motor has helped solve this problem. External instrumentation has been implemented quite easily with existing technology. However, internal instrumentation has been very difficult to implement. This has been mainly due to the complexity of breaching the motor case. A system was developed that transmits power through the case structure to a unique encoder/signal conditioner which then transmits the data back across the case structure for analysis. This was accomplished by magnetic coupling avoiding any disruption of the case structure. A detailed discussion of the magnetic coupling, signal conditioning and encoding functions will be presented.
