Multienvironmental Life Testing of Parts and Components in Rockets and Guided Missiles by Statistical Design

This paper suggests a method of studying the effect of environmental factors on missile parts and components for the following cases: 1. When the effects of preoperational environments are being investigated. 2. When environmental test facilities are sufficiently sophisticated to allow simultaneous application of operational environments to be made while the item is functioning. 3. When the first two conditions are satisfied and both types of information are being studied. The investigation of the behavior pattern of the items over the environmental space is carried out by combining censored life testing with statistical experimental designs and illustrating the results by response surfaces.
