Abstract
A spin-stabilizing assembly is usable with a cylindrical barrel having a longitudinal center axis, a vertical center axis, and a distal end. The assembly includes a gimbal piece, a spinner cage, and a spinner body. A first end of the gimbal piece engages an outer diameter surface of the barrel proximate the distal end. The spinner cage is configured to engage a second end of the gimbal piece, and to pivot with respect thereto about the vertical center axis. The spinner body is disposed radially within the spinner cage and defines multiple axial vanes. The vanes, in response to impingement on the axial vanes of exhaust gases discharged from the distal end of the barrel, rotate the spinner body about the longitudinal center axis. Rotation results in impedance along the vertical center axis which minimizes vertical displacement or motion of the distal end.
