As this vortex lies beside and behind the wing, it does not contribute to lift. The delta traps this over the rear surface of the wing and uses it for lift. Vortex lift is a form of lift force lift generated by delta wing s operating at high angle of attack angles of attack . How it works Vortex lift works by capturing vortex vortices generated from the sharply swept leading edge of the wing. The vortex, formed roughly parallel to the leading edge of the wing, is trapped by the airflow and remains fixed to the upper surface of the wing. As the air flows around the leading edge, it flows over the trapped vortex and is pulled in and down to generate the lift. Advantages and disadvantages The major advantage of vortex lift is that it allows angles of attack that would Stall flight stall a normal wing. Since it does not require camber aerodynamics camber to generate lift, but does require significant sweep back, vortex lift is utilized by most supersonic aircraft for landing the characteristic bending nose of the commercial Concorde was built to allow the pilots to see over the nose during landing, when the aircraft was at a very high angle of attack. The disadvantage of vortex lift is the Drag physics drag that it produces. Vortices are a primary cause of drag in most aircraft, and the large vortices generated when using vortex lift cause correspondingly high drag. This high drag can actually be considered advantageous during ... DEFAULTSORT Vortex Lift Category Aerodynamics Category Vortices Aviation stub ko pl No no ... more details

It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off center. As the motor runs the rubber piece oscillates rapidly in a circular motion. When a test tube or other appropriate container is pressed into the rubber cup or touched to its edge the motion is transmitted to the liquid inside and a vortex is created. Most vortex mixers have variable speed settings and can be set to run continuously, or to run only when downward pressure is applied to the rubber piece. Vortex mixers are quite commonplace in bioscience laboratories. In cell culture and microbiology laboratories they may be used to suspension chemistry suspend cells. In a biochemistry biochemical or analytical chemistry analytical laboratory they may be used to mix the reagent s of an assay or to mix an experimental sample and a dilutant . The vortex mixer was invented by the Kraft brothers Jack A. Kraft and Harold D. Kraft while working for Scientific Industries a laboratory equipment manufacturer . A patent was filed by the Kraft brothers on April 6, 1959 and granted on October 30, 1962 US patent 3,061,280 . Scientific Industries still makes a version of this original vortex mixer.

No footnotes date April 2009 In superconductivity , a Josephson vortex after Brian David Josephson Brian Josephson from Cambridge University is a vortex of supercurrent in a long Josephson junction LJJ . The supercurrents circulate around the vortex center which is situated inside the Josephson barrier. In contrast to Abrikosov vortex Abrikosov vortices in type II superconductors , a Josephson vortex has no normal core . Usually the Josephson vortex s supercurrents create a magnetic field with the total flux equal to math Phi 0 math &mdash a magnetic flux quantum single flux quantum . Such a vortex is therefore called a Josephson fluxon . It has been shown that under certain conditions a propagating Josephson vortex can initiate another Josephson vortex. This effect is called flux cloning or fluxon cloning . Although a second vortex appears, this does not violate the conservation of the single flux quantum. Recently When date February 2011 it was demonstrated by Hilgenkamp et al. that Josephson vortices in the so called 0 &pi LJJ can also carry half of the magnetic flux quantum flux quantum , and are called semifluxon s.
