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.
The vortex ring state (VRS) is a dangerous aerodynamic condition that may arise in helicopter flight, when a vortex ring system engulfs the rotor, causing severe loss of lift. Often the term settling with power is used as a synonym, e.g., in Australia, the UK, and the US, [ 2 ] [ 3 ] [ 4 ] but not in Canada, which uses the latter term for a ...
Abrikosov found that the vortices arrange themselves into a regular array known as a vortex lattice. [7] Near a so-called upper critical magnetic field, the problem of a superconductor in an external field is equivalent to the problem of vortex state in a rotating superfluid, discussed by Lars Onsager and Richard Feynman.
Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air ...
The Verification of the Origins of Rotation in Tornadoes Experiment (or VORTEX) are field experiments that study tornadoes. VORTEX1 was the first time scientists completely researched the entire evolution of a tornado with an array of instrumentation , enabling a greater understanding of the processes involved with tornadogenesis .
GM denied the problems and attempted to protect the Firenza's reputation through deceptive marketing before withdrawing it from the Canadian market in early 1973. [54] The Disaffected Firenza Owners Association attempted to sue General Motors, but Canada lacked laws establishing class-action lawsuits at the time, prompting Prime Minister Pierre ...
In today’s Inside Coverage, Jason Fitz, Charles Robinson, and Frank Schwab dive into a wild NFL week filled with coaching rumors, locker room tension and playoff implications.
The horseshoe vortex model is a simplified representation of the vortex system present in the flow of air around a wing. This vortex system is modelled by the bound vortex (bound to the wing) and two trailing vortices , therefore having a shape vaguely reminiscent of a horseshoe .
