LCR Electronics has completed the rigorous AS9100 quality management system (QMS) standard certification. The AS9100 quality management system is a stringent standard specific to the aerospace industry and includes the ISO 9001:2008 standard, in addition to several complementary requirements. It is recognized by all major aerospace OEMs and is designed to meet their complex and … [Read more...]
Project to Study Carbon Nanotubes Impact on Electrical Conductivity in Composite Materials
Australian materials company, Quickstep Holdings is collaborating in a European program to study the use of nanotechnology in enhancing the properties of composites deployed in the transportation sector. The project is being undertaken by the company’s German subsidiary, Quickstep. It will research the introduction of carbon nanotubes into host composites that could enhance … [Read more...]
Troubleshooting Radiated Emissions Using Low-Cost Bench-Top Methods
Kenneth Wyatt Wyatt Technical Services LLC Editor's Note: Click on the pdf icon at left for a printable copy of this article. Because time-to-market and budget factors often drive many of today’s high-tech designs, electromagnetic compatibility (EMC) issues often surface at the last moment in the design cycle, potentially delaying product introductions. Very often, simple … [Read more...]
New EMC Requirements for Commercial Avionics: RTCA/DO-160G
Erik J. Borgstrom, Environ Laboratories LLC, Bloomington, Minnesota, US OVERVIEW RTCA/DO-160G, Environmental Conditions and Test Procedures for Airborne Equipment, prepared by RTCA Special Committee 135, was issued on December 8, 2010, superseding the previous version, DO-160F [1]. DO-160G covers standard procedures and environmental test criteria for testing airborne … [Read more...]
Aircraft Faces Tests in Anechoic Chamber
As part of a continuing program of testing electromagnetic environmental effects on the E-2D advanced Hawkeye AA-5, the aircraft spent time suspended in the anechoic chamber. AA-5 is the first full production E-2D, and will be put to use by the warfighter when testing is completed later this spring. Using electromagnetic energy, the team simulates navigation, GPS, LINK 16, IFF, … [Read more...]
Tears Prompt Electromagnetic Inspections on 737s
During a flight on April 4, a Southwest Airlines plane had a section of fuselage tear from the plane. Federal aviation officials were preparing to issue an order Tuesday that calls for emergency inspections on 80 U.S.-registered Boeing 737 jetliners with histories similar to that Southwest Airlines jet, which had been pressurized and depressurized 39,000 times before a … [Read more...]
Inflight Wi-Fi Interfering with Flight Critical Electronics
Inflight Wi-Fi and cellphone services, which transmit low power microwave radio signals within an aircraft's fuselage, has been found to be interfering withflight critical electronics. This latest finding was made by Boeing while testing inflight Wi-Fi equipment for use on its next generation 737 twin-engined aircraft. The plane maker found that a certain type of new, brighter … [Read more...]
European Space Agency to Test High-Power Laser Diodes
Typical laser system applications in space include precision range measurements, radar-like “lidar” systems to gather a complete picture of surface terrain or three-dimensional samplings of planetary atmospheres and laser-based space communications with high bandwidth and minimal electromagnetic interference. ESA has selected Yokogawa digital oscilloscopes for its European … [Read more...]
Russian Satellite Crash May Have Been Caused By EMI
A Russian Geo-IK-2 satellite launch failed “because of possible external electromagnetic interference from a sea-, land- or air-based source.” The satellite was launched by a rocket converted from a SS-19 intercontinental ballistic missile that apparently did its job sufficiently well, but an additional Briz-KM booster malfunctioned. Finally, the Geo-IK-2 was boosted to an … [Read more...]
NASA Satellite Completes EMI/EMC Testing
The NASA National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) climate/weather satellite is undergoing flight environmental testing. The NPP satellite began environmental testing in November 2010 and has successfully completed vibration, acoustics, shock environments and electromagnetic compatibility/electromagnetic interference … [Read more...]
