System and method for improving performance of a weapon barrel
View Patent ↗A harmonic barrel dampener operable to increase the accuracy of a weapon having a barrel. According to at least one embodiment, a harmonic barrel dampener comprises an outer portion that substantially encases or enwraps a significant portion of barrel, and wherein the harmonic barrel dampener further comprises at least one acoustic dampening material contained between the outer portion and a weapon's barrel, resulting in improved accuracy of projectiles fired from the weapon.
1. A harmonic barrel dampener comprising:
an outer portion sized to substantially enwrap a selected weapon barrel, the outer portion having an interior chamber and an exterior portion; and
an elastomeric dampening material substantially filling a volume defined by the interior chamber and an outer surface of a weapon barrel;
the dampening material capable of attenuating a spectrum of vibrational frequencies generated by the weapon barrel in operation.
2. The harmonic barrel dampener of claim 1 , wherein the outer portion is of a length such that more than 75% of the length of the weapon barrel is substantially enwrapped therein.
3. The harmonic barrel dampener of claim 2 , wherein the dampening material is an elastomeric polymer.
4. The harmonic barrel dampener of claim 3 , wherein the dampening material is selected from a group consisting of epoxy and polysulfide.
5. The harmonic barrel dampener of claim 4 , wherein the dampening material is poured into the volume defined by the interior chamber and an outer surface of a weapon barrel in an unpolymerized state and allowed to cure in situ.
6. The harmonic barrel dampener of claim 5 , further comprising a retainer ring having an outer diameter approximately equal to a diameter of the outer portion, the retainer ring further comprising an opening sized such that the weapon barrel may protrude therethrough.
7. The harmonic barrel dampener of claim 6 , wherein the retainer ring is operable to compress the weapon barrel.
8. The harmonic barrel dampener of claim 7 , wherein the dampening material is cured while the barrel is compressed by the retainer ring.
9. The harmonic barrel dampener of claim 8 , wherein the dampening material retains elastomeric properties over a range of temperatures of −40° F. to 250° F.
10. The harmonic barrel dampener of claim 8 , wherein the harmonic barrel dampener is configured to improve an accuracy of a weapon barrel by at least 25% over a non-modified state when compared using a test selected from a group consisting of mean radial dispersion and Kolmogorov-Smirnov Test.
11. A harmonic barrel dampener comprising:
an outer portion sized to substantially enwrap a selected weapon barrel, the outer portion having an interior chamber and an exterior portion, wherein the outer portion is of a length such that more than 75% of the length of the weapon barrel is substantially enwrapped therein;
an elastomeric dampening material substantially filling a volume defined by the interior chamber and an outer surface of a weapon barrel, wherein the dampening material is an elastomeric polymer selected from a group consisting of epoxy and polysulfide;
a retainer ring having an outer diameter approximately equal to a diameter of the outer portion, the retainer ring further comprising an opening sized such that the weapon barrel may protrude therethrough, wherein the retainer ring is operable to compress the weapon barrel;
wherein the dampening material is operable to attenuate vibrations of the weapon barrel in operation when poured into the volume defined by the interior chamber and an outer surface of a weapon barrel in an unpolymerized state and allowed to cure in situ while the barrel is compressed by the retainer; and
wherein the harmonic barrel dampener is configured to improve an accuracy of a weapon barrel by at least 25% over a non-modified state when compared using a test selected from a group consisting of mean radial dispersion and Kolmogorov-Smirnov Test.
