Increased System Worth Through Reliability Design Review

It is the purpose of this paper to present the results, conclusions and recommendations of the analysis of electronic equipment to provide the optimum system worth, with regard to reliability and performance. Additional parameters set up in the three mathematical regimes are minimum weight, minimum geometric space envelope, schedule time delays, and cost trade-offs. This paper further proposes a methodical engineered system which attaches numerical quantities and mathematical relationships which may be measured and compared to parameters determining electronic equipment system worth. Value engineering concepts are thus generalized for electronic equipment to include many significant, parameters for optimum system worth -- with probability of success and performance replacing cost reductions as the prime yardstick for analytical trade-off comparisons. Forcing function inputs include transportation and handling loads, gunfire, takeoff, landing, flight maneuvers and catapult dynamic loads. These are mathematically treated as random vibrations, random shock, sustained acceleration, steady-state sinusoidal vibrations at resonance, sweep-cycle sinusoidal vibrations, and sudden impulse shock. The electronic equipment is analyzed under all probable conditions of the true environment plus the requisite conditions of the governing military specifications. Critical deflections, rotations, stresses and deformations are determined at all key substations of each dynamic subsystem of the electronic equipment. Each electronic tube is subdivided into the significant subsystems: 1. Cantilevered gun and assembly 2. Cantilevered heater and button assembly 3. Ceramic rods and helix 4. Outer envelope 5. Collector end 6.
