Vortex Optics is a DBA of Sheltered Wings, Inc., which was incorporated in Wisconsin in 1989. Sheltered Wings, Inc. DBA Vortex Optics began in 2002. In 2022 after extensive research, testing and reviews Vortex became an official supplier and contractor to the American Military as the U.S. Army selected Vortex‘s XM-157 fire control system for its Next Generation Squad Weapon program.
Vortices are points in 2D fields and lines in 3D fields (as they have codimension two). Integrating the phase of the field around a path enclosing a vortex yields an integer multiple of 2 π. This integer is known as the topological charge, or strength, of the vortex. A hypergeometric-Gaussian mode (HyGG) has an optical vortex in its center ...
Spotting scope eyepieces are usually interchangeable to adapt for different magnifications, or may have variable zoom to give a range of magnifications. Magnifications less than 20× are unusual, as are magnifications more than 60× since the latter can lead to poorer image brightness, a narrow field of view and too much image shaking, even on ...
Because the sight axis (which is a straight line) and the projectile trajectory (which is a parabolic curve) must be within the same vertical plane to have any chance of intersecting, it will be very difficult to shoot accurately if the sights are not perpendicularly above the gun barrel (a situation known as canting) when aiming or sighting-in.
The Colt Diamondback is a revolver manufactured by Colt's Manufacturing Company of Hartford, Connecticut, in calibers of .22 LR and .38 Special. Inspired by the successful Colt Python , the Diamondback was manufactured from 1966 to 1988 and was available in barrel lengths of 2½, 4, and 6 inches.
A C79 Optical Sight. The C79 optical sight (SpecterOS3.4x) is a telescopic sight manufactured by Elcan.A variant, the M145 Machine Gun Optic is in use by the US military. It is 3.4×28, meaning 3.4x magnification, and a 28mm diameter objective lens.
In fluid dynamics, a vortex (pl.: vortices or vortexes) [1] [2] is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. [ 3 ] [ 4 ] Vortices form in stirred fluids, and may be observed in smoke rings , whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone , tornado or dust ...
The vortex is named after Micaiah John Muller Hill who discovered the exact solution in 1894. [2] The two-dimensional analogue of this vortex is the Lamb–Chaplygin dipole . The solution is described in the spherical polar coordinates system ( r , θ , ϕ ) {\displaystyle (r,\theta ,\phi )} with corresponding velocity components ( v r , v θ ...
