Analyzing New Vortical Flows Over A 76/40 Double Delta Wing Using Detached-eddy Simulations
2013-06-28 14:34:48

Science China Press The double delta wing is a simplified configuration used for studying aircraft aerodynamics. It is composed of a highly-swept delta wing connected in front of the main delta wing with a smaller sweep, reflecting the combination of a leading edge extension and the swept main wing. The aerodynamic performance of such wings, which includes the behavior of the leeside vortical flows at moderate and high angles of attack (AoA) at low speed, is of research interest. The...

Dampers reduce cable vibration for daring stunt. Spartanburg, S.C. (PRWEB) June 27, 2013 Twice in the past two years, daredevil Nik Wallenda has completed high-wire walks on two-inch-thick metal cables that were stabilized with AFL’s Stockbridge Dampers. For his most recent stunt at the Grand Canyon, 20 dampers were attached to Wallenda’s cable as he tiptoed from one side of the Little Colorado River Gorge to the other. AFL’s Stockbridge Dampers are used to eliminate cable...

The boomerang is a flying tool, made of wood or carbon fiber-reinforced plastic, with a curved shape that is often used as a weapon or for sport. They have also been made of bones and come in many different shapes and sizes depending on their geographic or tribal origins and their intended function. The most commonly recognizable type is the returning boomerang which travels in an elliptical path and returns to its point of origin. The returning boomerang has lopsided wings in order to create...

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...
