Flexible Wing Flap Reduces Noise and Drag

Shape-changing flexible wing flaps FlexSys Ann Arbor, MI 734-975-9233 www.flxsys.com FlexSys designed and built two experimental flaps for Armstrong Flight Research Center’s Gulfstream G-III Aerodynamics Research Test Bed aircraft. Researchers will replace the airplane’s conventional 19-foot-long aluminum flaps with the advanced, shape-changing assemblies that form continuous, bendable surfaces. The new flexible flaps are being prepared for ground vibration testing in NASA Armstrong’s Flight Loads Laboratory, followed by fit checks and eventual installation.

Control Software Navigates Lunar CubeSats

GNAT Programming Studio and GNAT Pro Compiler Software AdaCore New York, NY 866-787-4232 www.adacore.com Vermont Technical College’s Lunar CubeSat, measuring only 10 × 10 × 10 cm and weighing 1.1 kg, was launched into a 500-km earth orbit. The small satellite will remain in orbit for about three years to test the systems that will be used for an eventual lunar mission. The CubeSat project is part of NASA’s ELaNa (Educational Launch of Nano-satellites) IV program. The CubeSat’s navigation and control software was developed in SPARK/Ada using AdaCore’s GNAT Programming Studio (GPS) IDE and GNAT Pro compiler; the SPARK toolset from Altran, headquartered in Neuilly-sur-Seine, France, proved the absence of runtime errors.

Lunar Simulants Provide Critical Tests for Moon Missions

NU-LHT lunar simulant Zybek Advanced Products (ZAP) Boulder, CO 888-469-0110 www.zybekap.com Lunar simulants are a critical aspect of the return to the Moon and a planned lunar outpost. All mechanical equipment, chemical processes, and human health studies will be tested extensively with simulants prior to deployment. Zybek Advanced Products’ NU-LHT (NASA-USGS — Lunar Highlands Type) simulant is used by NASA to represent the lunar highlands area, and contains a complex mixture of glass, agglutinate, jagged particulates, synthetic minerals, and natural minerals from select terrestrial sources. While glass and crystal structures exist terrestrially, the agglutinate structure is not available on Earth.

Beyond Smart Vision

Many Higher-End Vision Projects Require Capabilities Not Built Into Smart Vision SystemsWith the proliferation of smart vision (SV) cameras and platforms it is understandable that automation engineers begin to define vision technology capabilities based on the performance and features of these popular and easy to implement products. Although they are effective for addressing a broad range of common vision applications and requirements, there are compromises made to make SV products easy to use and less costly, the obvious being reduced vision processing and performance capabilities.

LED Street Lights Reduce Energy Consumption by 72% at Power Station

When the NRG power plant in El Segundo, Calif., was redesigned, two towers were demolished which caused extensive light from the plant to bother local neighbors. In an effort to get rid of this light pollution and update old lighting fixtures at the same time, NRG turned to LEDtronics, Inc. for assistance.

Production Company Uses LED Street Lights To Illuminate Dark Parking Lot

Solar Energy Technologies, Inc., Hialeah, FL MaxLite, West Caldwell, NJ Imagina US is a pioneer production company in the U.S. Hispanic TV industry that has a newly built headquarters in Miami, Florida. Owners were seeking low-wattage outdoor lighting for the facility’s parking lots. At first, the owners were looking at 400-watt metal halide fixtures, however, they wanted to consider lower wattage and better quality LED lighting fixtures.

Customized Goniophotometer System Tests High Intensity Obstruction Lights

Hughey & Phillips (H&P), Urbana, OH Hughey & Phillips (H&P) designs and manufactures flashing and steady state anti-collision lighting used on above-ground obstructions like communication towers, antennas, buildings, wind turbines, grain elevators, smoke stacks, bridges and other man-made structures that are potential collision hazards for aircraft. Used as either standalone fixtures or as part of integrated systems, these low, medium, and high intensity lighting devices illuminate obstructions to aerial navigation as specified by the FAA, FCC, ICAO, DGAC of Mexico and Transport Canada. The required light output intensity of H&P’s products increases with altitude - the higher the elevation, the greater the required output intensity.
