Abstract:
A harmonic optimization technology system comprising:A. a harmonic oscillator affixed by means at a muzzle of a rifle barrel; the barrel having a bore, a bore axis, a barrel surface, a bore surface and a rifle cartridge chamber; the cartridge chamber distal from the muzzle; the barrel having a short term vibrational response, to the combustion of a cartridge in the cartridge chamber and to the transit of a bullet through the barrel; the muzzle having a dispersion angle relative to the bore axis; the harmonic oscillator having harmonic oscillator mass, wall thickness, material composition, extension length and flexible cylinder discontinuities;B. an inertial mass affixed by means intermediate the rifle cartridge chamber and the muzzle; the inertial mass reducing the transmission of the short term vibrational response generated near the cartridge chamber to the barrel proximal the muzzle; the inertial mass, in relationship to the harmonic oscillator, bending the barrel proximal the muzzle thereby reducing the dispersion angle at the muzzle; the harmonic oscillator is tuned producing a standing wave, corresponding to the frequency of the short term vibrational response, between the inertial mass and the harmonic oscillator mass, that bends the barrel proximal to the muzzle, so that the muzzle dispersion angle is minimized;C. a barrel spring suspension system having means, affixed proximal the cartridge chamber intermediate the cartridge chamber and the inertial mass, for biasing and vibrational coupling between the barrel and a rifle stock; vibrational coupling boundary conditions existing between the barrel and the rifle stock; the barrel spring suspension system thereby providing an adjustment of said vibrational coupling boundary conditions and an adjustment to the short term vibrational response of the barrel; andD. wherein a rifle with any ammunition load achieves improved bullet accuracy by reducing the magnitude of the barrel muzzle dispersion angle caused by short term vibrational response.
