01 Aug 13. Elmo Motion Control will present its cutting-edge, ultra-high current Gold Eagle servo drives at AUVSI 2013 in Washington DC. With ratings of 150 A, 300 A and 600 A and operating voltages ranging from 16 to 96 VDC, the newest Gold Eagle family members are specifically designed to meet the unique requirements of unmanned applications such as unmanned vehicles, turrets and other systems that require repeated power bursts for relatively long time periods. To enhance the compact Gold Eagle package with new ultra-high current specifications, Elmo combined its proprietary power conversion technology together with an advanced pulse-width modulation (PWM) “follower” algorithm. This is the first time such high current has been achieved in such a small military-grade package. At AUVSI Elmo will also present complete motion solutions for a wide range of unmanned applications, bringing multiple benefits to systems like missile winglets and UAVs. Visitors will also be able to see the Company’s motion control solutions for applications with multiple integrated axes. Among Elmo’s products are military-grade multi-axis motion controllers that can control up to 100 servo axes in any motion scenario and are EtherCAT and CANopen compatible.

25 Jul 13. The orders pipeline in the aviation industry may be thinner than expected, but innovation is still soaring as showcased by recent achievements and real demonstrations. Novel solutions presented by major industry players at the recent Air Paris Show, could allow fuel savings and make the aircraft environmentally friendly. The buzz word is
“electric”, with electric systems/engines to be used for faster taxi outs and more aircraft maneuvers. Are these the first tangible signs of the all-electric aircraft revolution? If these solutions see wider adoption, they may well pave the way for an all-electric aircraft. There are two main reasons justifying this market move. First, it is said to fundamentally enhance each aircraft availability rate, as systems and engines would be more reliant, and hence with less support required.
The second advantage is also financial. With less reliance on fuel, airliners should be less affected by rising oil prices and passenger fares could significantly decrease. Consequently, the promised return of investment may be attractive enough to encourage investments despite the high costs of going all-electric. For now, the focus is primarily on replacing aircraft pneumatic and hydraulics systems to make the airplane lighter and faster. Engineers are currently working on how electric drives can provide better efficiency when compared to mechanical transmissions and actuators. Eventually, maintenance costs will decrease as system failures get easier to track and fix. The final and golden milestone will be a completely electric power system and thrust. “As soon as aircraft propulsion becomes fully electric, (bio) fuels, heat engines, and combustion steel and aluminum, will be by-gone memories of the twentieth century,” added Ms. Leboulanger. Despite all developments being on-track, recent debates on lithium-ion versus nickel-cadmium batteries give the impression that the 100% electric aircraft is not ready to take off. However, there were some cutting-edge aircraft in the static display area of the Paris Air Show, which already flew earlier this year. (Source: Yahoo!/PRNewswire)
