Abstract : The patent concerns a system for immobilizing solid propellant grain while providing an improved mechanical suppression of resonant burning. It comprises a small diameter, tension spring extending within the center bore of the grain. The spring is fastened at the forward end to a spacer abutting the grain while the other end is fastened to a reasonator rod positioned within the center bore. An immobilizing force is thus exerted upon the grain which does not appreciably vary with ambient temperature changes. The spring is free to oscillate in the longitudinal and transverse modes thus serving more effectively as a mechanical resonance suppressor.
