Tests Of 757 Vertical Tail With Advanced Technology Completed
2013-11-14 16:12:24

NASA NASA's Ames Research Center and NASA's Langley Research Center, in partnership with The Boeing Co., have completed wind tunnel testing of a full-scale Boeing 757 vertical tail model equipped with active flow control technology. A major objective of the tests was to show active flow control can enhance the performance of a vertical tail enough to enable future designers to reduce the size of the structure for a whole family of airplanes. That could reduce the penalties related to...

Future Submarines May Draw Inspiration From Stingray Mobility
2013-11-14 07:02:17

April Flowers for redOrbit.com - Your Universe Online Stingrays have a unique swimming movement that allows them to move through the water with ease. A new study from the University of Buffalo (UB) and Harvard University is examining those movements to design more agile and fuel-efficient unmanned underwater vehicles. Such vehicles would allow scientists to study the mostly unexplored ocean depths more efficiently, as well as serving during clean up activities or rescue efforts....

Lockheed Introduces Son Of Blackbird Hypersonic Jet
2013-11-07 12:02:57

Peter Suciu for redOrbit.com – Your Universe Online While satellites and drones can provide an eye-in-the-sky for those on the ground, the military still has a use for the good old-fashioned spy plane - especially a really speedy one. For years the work of providing a quick look at the ground fell to the Lockheed Martin SR-71 Blackbird, which, as the fastest plane in the world, could fly crews from New York to London in less than two hours. The Blackbird was capable of reaching speeds...

Splattered Bugs Can Be A Real Drag For Aircraft
2013-11-04 13:12:52

Brett Smith for redOrbit.com - Your Universe Online Splattered bugs on your windshield can be gross to look at and they can even obstruct your view. However, for some, the ordeal can be much more of a problem than just an unsightly nuisance. For pilots, splattered bug guts can be a real drag, quite literally. If an airplane wing accumulates enough splattered bugs, it disrupts the flow of air over the wing and creates more drag on the plane – causing increased fuel consumption....

Jet measures 20 to 150 nanometers in diameter — just a few hundred water molecules across Fluid jets are all around us: from inkjet printing, to the “Old Faithful” geyser in Yellowstone National Park, to cosmological jets several thousand light years long. A Northwestern University researcher with collaborators from Cambridge University, Oxford University, and Centro Nacional de Biotecnología have recently verified the classical Landau-Squire theory in the tiniest submerged jet....

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...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
