THE NAVY NEEDS RUGGED, FAST-RESPONSE GAS TEMPERATURE MEASURING CAPABILITY; A SPECIFIC APPLICATION IS IN MEASURING MISSILE LAUNCHER EJECT CHAMBER TEMPERATURE TRANSIENTS.

THE NAVY NEEDS RUGGED, FAST-RESPONSE GAS TEMPERATURE MEASURING CAPABILITY; A SPECIFIC APPLICATION IS IN MEASURING MISSILE LAUNCHER EJECT CHAMBER TEMPERATURE TRANSIENTS. THIS PROPOSAL DESCRIBES A THERMAL PROBE SYSTEM CAPABLE OF MEASURING GAS TEMPERATURE CHANGES OF HUNDRED OF DEGREES FAHRENHEIT IN TIMES OF LESS THAN TEN MILLISECONDS. THIS METHOD CAN BE EXTENDED TO ANY TEMPERATURE ENVIRONMENT OF GREATLY IMPROVE TIME RESPONSE WITHOUT SACRIFICING PROBE DURABILITY. THE TECHNIQUE DESCRIBED USES COMMERCIALLY AVAILABLE PROBE MATERIALS AND SIGNAL CONDITIONING HARDWARE TO ACHIEVE THIS PERFORMANCE IN A SYSTEM THAT IS SIMPLER AND MORE RELIABLE THAN RADIATION PYROMETRY OR LASERBASED THERMOMETRY.
