Abstract:
The report reviews investigations into the design, manufacture, and test of multiaxial stress sensors for measuring the components of stress in a solid propellant grain. A 6-element 3D, triazial sensor and a 3-element biaxial sensor were developed. Techniques for calibration are discussed, together with the problems of calibrating a 3D gage. The final phase of the program consisted of the manufacture of a solid grain, inert propellant STV containing a number of 3D and biaxial sensors, together with six diaphram normal sensors for comparison. The results of the STV tests under thermal, hydrostatic, and differential pressure tests are described.
