  • Strain measurement device, a solid rocket motor including same, and related methods
    Patent number: 9394853
    Abstract: A strain measurement device includes a reference material, and a displacement sensor configured to detect relative changes in distance between the sensor and the reference material. At least one of the displacement sensor and the reference material is coupled with a pre-cured elastomeric material. The displacement sensor generates a data signal to a processor that is configured to determine a strain of another elastomeric material based at least in part on the data signal received from the sensor. A displacement sensor and a reference material may be positioned within an elastomeric material within a casing of a solid rocket motor for determining strain experienced by the elastomeric material, such as the propellant of the solid rocket motor. A method includes installing a sensor of an elastomeric material. Another method includes determining strain of an elastomeric material of a solid rocket motor.

  • High molecular weight polycaprolactone prepolymers used in high-energy formulations
    Patent number: 4775432
    Abstract: Poly(caprolactone) polymers are provided having molecular weights of 4000 or higher, are used to form propellant binders. When the high molecular weight poly(caprolactone) polymers are used in propellant formulations and cured with isocyanates of adequate functionality, propellants are produced having improved stress and strain characteristics relative to presently formulated propellants having binders of cured, lower molecular weight poly(caprolactone) polymers.
