FIVE series of Structural Test Vehicle studies were conducted to verify that several types of embedded stress transducers and their installation methods could be successfully used with the fiberglass chamber of the Minuteman 3, Third Stage motor. The results showed that the transducers could be installed with lead-wires brought out through the case wall without causing fluid leakage paths or degrading the case structure. Potting of normal stress transducers in an inert trowellable insulation was shown to yield the same stress measurements as potting them in propellant. Ruggedized shear transducers were shown to function successfully up to the point of propellantliner interface failure in shear. Successful performance of elastomeric failure event gages in the detection of bondline shear failure was demonstrated.
