  • Precursor formulations for a liner, a rocket motor including the liner, and related methods
    Patent number: 9416217
    Abstract: A precursor formulation of a liner comprising a polymer and at least two curatives. One of the at least two curatives comprises a more reactive curative and the other of the at least two curatives comprises a less reactive curative. The more reactive curative is formulated to crosslink the polymer. A method of lining a rocket motor is also disclosed, as is a rocket motor including the liner.

  • Erosion resistant-low signature liner for solid propellant rocket motors
    Patent number: 6054521
    Abstract: The present invention concerns an erosion resistant, low signature liner for solid propellant rocket motors and rocket motors having such a low signature liner. The liner combustion products in the exhaust plume have low visibility in the IR and visible light spectra which is essential for use in low signature solid propellant rocket motors. The liner also forms an in-situ protective layer at elevated temperatures for enhanced erosion resistance. These erosion resistant properties eliminate the need for supplemental case insulation which would contribute additional smoke and combustion products to the exhaust plume as well as add additional costs and inert weight to the motor.
