Abstract:

The primary purpose of this program is to investigate the properties and behavior of elastomeric insulation materials during multiple restart conditions, and the influence of these properties on materials performance. During the first phase of work, tests were conducted to determine the five representative materials for correlation at a later date with motor performance. Designs, test firings, and performance analyses were completed for the three correlation motors single-pulse, two-pulse, and three-pulse. The effects of heat soaking and thermal cycling on the lap shear strengths of insulation-case bonds were determined. Author
