Abstract:

The designer of a new and complex instrument for use in missiles is unable to predict the probable percentages of successful operation from tests because of the small number of models available. Analysis of the physical basis for high reliability suggests that confidence in an instrument can be obtained by a method of complete environmental testing that is formulated mathematically ck, Instrumentation, Satellites, Subminiature electron tubes, Test equipment. The designer of a new and complex instrument for use in missiles is unable to predict the probable percentages of successful operation from tests because of the small number of models available. Analysis of the physical basis for high reliability suggests that confidence in an instrument can be obtained by a method of complete environmental testing that is formulated mathematically herein. This method has been applied to the testing of a family of high quality amplifiers in an environmental c amber permitting continuous and simultaneous variation of temperature, atmospheric pressure, and vibration, with the result that the designers obtained greatly increased confidence in the survival capability of the instrument.
