NEW YORK, Dec. 15, 2011 /PRNewswire-iReach/ -- SourceOne Inc, an energy management and advisory services company, announced that their client, The Town of Hempstead, New York, completed major construction on a 100 kW wind turbine. The Town of Hempstead received over $4.5M in federal funding for energy projects under the Energy Efficiency and Conservation Block Grant (EECBG) program. SourceOne has been working with the Town as project manager and grant administrator for over 2 years....
NASA's Marshall Space Flight Center in Huntsville, Ala., is entering into a space act agreement with Sierra Nevada Corp. Space Systems of Louisville, Colo., to provide key wind tunnel testing of a new spacecraft designed to transport crew and cargo to and from the International Space Station. Marshall will perform wind tunnel tests for Sierra Nevada's Dream Chaser orbital crew vehicle, a spacecraft that looks like a small space shuttle. The tests will simulate speeds ranging from Mach .2,...

Hui Hu pulled a model wind turbine from the top of an office filing cabinet. The turbine tower was just 10 inches high. Its three blades were 10 inches in diameter. It was a perfect 1:320 scale reproduction of the 80-meter diameter wind turbines spinning across Iowa, the country's second-ranked state in installed wind power capacity. That mini turbine is helping a research team led by Hu, an Iowa State University associate professor of aerospace engineering, understand how hills, valleys...
[ Video 1 ] | [ Video 2 ] Australian vision scientists today unveiled a novel way to help pilotless aircraft accurately determine their heading and orientation to the ground - by imitating how insects do it. The technology can improve the navigation, flight characteristics and safety for civil and military aircraft, as well as pilotless drones says Mr Richard Moore, a researcher at The Vision Centre and The Queensland Brain Institute at the University of Queensland. “UAVs (unmanned...
SOUTHAMPTON, Pa., Nov. 30, 2011 /PRNewswire/ -- Static testing will soon begin on Environmental Technology Corporation's ("ETC") ATFS 400 Model 31 (http://www.etcusa.com/). The ATFS-400-31 is a high performance human centrifuge that was designed and manufactured by ETC's Aircrew Training Systems (ATS) business unit. The ATFS-400-31 will be delivered to the United States Air Force next year and will be used to conduct high G training for operational and aeromedical aircrew, research...
SOUTHAMPTON, Pa., Nov. 22, 2011 /PRNewswire/ -- Environmental Tectonics Corporation ("ETC") (http://www.etcusa.com) shipped the last major subassembly of its GL-6000 today to Wright Paterson Air Force Base. The cockpit capsule with its rotating gimbals and linear sleds represent the last and most important parts of the GL-6000 operation. The GL-6000 is an advanced training and research device that was competitively awarded by US Navy to ETC. GL-6000 was sold by the Aircrew...
The US Army conducted its first flight test of its new Advanced Hypersonic Weapon (AHW), launching the high-tech bomb from the Pacific Missile Range Facility in Kauai on Thursday. After launch, the rocket glided through the upper atmosphere over the Pacific “at hypersonic speed” before reaching its target on the Kwajalein atoll in the Marshall Islands, according to a statement made by the Pentagon. The rocket made the trip from Kauai to Kwajalein -- some 2,500 miles southwest of...
Max Planck scientists discover gene switch responsible for flight muscle formation Flies are real flight artists, although they only have small wings compared to their body size. Scientists at the Max Planck Institute of Biochemistry in Martinsried near Munich, Germany, recently identified the genetic switch that regulates the formation of flight muscles. “The gene spalt is essential for the generation of the ultrafast super muscles,” emphasizes Frank Schnorrer, head of the research...

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...
