Abstract : The development and demonstration are described of techniques for analytical evaluation of aerospace equipment designs (Project ERIE) with respect to environments and missions applicable to vehicles of the 1975 era. Procedures currently applied and existing data are surveyed. Dynamic analysis utilizing environmental inputs is evaluated as potentially capable of reducing system test costs by a factor of one-third and development time for new space systems by as much as one-half if this technique is adequately applied in early design analysis. Development of a probabilistic model, encouragement of applicable standards for environmental testing and industry-wide formulation of appropriate component and module transfer functions are recommended. The model developed lends itself to detection of undersign for environment and avoidance of overdesign. Tradeoffs among component substitution, design and mission relaxation, avoidance of critical environments, environment control, mitigation of environmental effects and optimization between inherent reliability and maintenance are discussed.
