Abstract:

The objective of this program is to improve the capabilities of rocket motors using end-burning grains through 1 development of laboratory test procedures to be used as criteria for the evaluation of insulating materials, and 2 development of materials for application as motor case insulation. The development of the four laboratory test proceudres has continued. In the material development phase of the program, a new evaluation series was started which will define the relative merits of several resin binder materials according to their ability to minimize heating of the substructure during ablation. A comparison will be made by subjecting panels of refractory solids impregnated with the various resins to an oxyacetylene torch test. Author
