Stage 2: flow separation and the formation of a vortex disturbance is cast-off from the leading edge region of the airfoil. This vortex, called leading edge vortex ( LEV ) or dynamic stall vortex ( DSV ), provides an additional lift for the airfoil so long as it stays over the upper surface, and also noteworthy increases in nose-down pitching ...
[17] [18] In 2003, Atari historian Curt Vendel released the binaries and encryption keys for both cartridge and CD formats, allowing to run software without development hardware. [ 4 ] [ 19 ] All homebrew games are region free, as both systems do no enforce regional locking, but some titles do not work correctly on PAL consoles. [ 20 ]
Vortex Studio is a simulation software platform developed by CM Labs Simulations. It features a real-time physics engine that simulates rigid body dynamics , collision detection , contact determination, and dynamic reactions.

This takes place within 2 miles (3.2 km), or 4 minutes away from the tornado itself. [18] The team had 24 2 metres (6.6 ft) high portable Sticknets, which can be set up at various locations around tornado storm cells to measure wind fields, provide atmospheric readings, and record acoustically the hail and precipitation.

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 ...
The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing , of an aircraft as an infinitely thin sheet of discrete vortices to compute lift and induced drag .
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 .
