Aerometals has received PMA approval for spiral bevel gears for the main rotor transmission of the MD500. According to the company, the approval marks the first time the FAA has granted manufacturing approval for transmission gears to a company that is not the OEM. The testing required a test stand using a 500-hp electric motor instead of a gas turbine. The MD transmission is rated for 425 hp for up to five minutes, but Aerometals ran the gears for eight hours at 467 hp to satisfy FAA testing requirements.
Former U.S. Air Force pilot Sean Gillette announced yesterday the launch of a new “personal jet” program, the Saker S-1, a twin-engine two-seater capable of flying 1,600 nm and cruising at Mach 0.95. With twin vertical fins, tandem seating and short fighter-like wings and stabilizer, the S-1 brings to mind the Aviation Technology Group Javelin.
A Gulfstream G650 set a city-pair speed record last month on a flight between Shanghai and Newark, N.J., flying the 6,855-nm route in 13 hours and 32 minutes, the Savannah, Ga.-based aircraft manufacturer announced yesterday. The jet took off from Shanghai Hongqiao International Airport on April 18 carrying five passengers and four crewmembers. ATC restrictions kept the G650 below FL310 for the first hour before it was cleared to climb to its normal cruising altitude of FL410 to FL510.
An RAA-sponsored study into the fatigue effects of multi-segment flight operations has reached the end of its third and final stage, involving the development of so-called fatigue risk management systems (FRMS).
Alto Aviation, a supplier of business jet cabin audio systems, is urging completion and refurbishment centers to rethink speaker grille construction.
“It is one of the most common problems we encounter,” according to the Leominster, Mass.-based company. “Sound waves are made up of the compression and expansion of air [and] if air can’t move through the speaker grille, then the sound can’t get into the cabin.”
Alto recommends speaker coverings that are at least 50-percent open to ensure the best audio performance.
Spectro and its associated company, Jet-Care, have been named approved suppliers for debris and oil analysis services for all AgustaWestland AW139s. Spectro and Jet-Care use scanning electron microscopes to examine debris recovered from oil samples, filters and chip detectors. Identifying the particle size and composition of metallic and non-metallic debris can help to flag the components responsible for the debris for replacement before they fail.
UK-based Spectro and its U.S. sister company Jet-Care (Booth No. C3516), providers of equipment condition monitoring services, announced their appointment by AgustaWestland as approved suppliers for debris and oil analysis services for all AW139s. Spectro and Jet-Care utilize the advanced analytical capabilities of scanning electron microscopes for in-depth examination of debris recovered from oil samples, filters or chip detectors, allowing detailed investigation into the metallic and non-metallic debris, helping to pinpoint the component generating the debris.
Mecaer Aviation Group has been selected by Eurocopter to design and manufacture the landing gear shock absorbers for the new-generation X4 helicopter. The company is responsible for the design, engineering, certification, production and after-sales support of the landing gears, and will provide to Eurocopter the absorbers for the nose landing gear and the two main landing gears, in addition to the nose landing gear electrical wheel lock actuator.
LMB of Malemort, France, is showcasing a range of its high-performance/high-reliability electric fans, blowers and motors here at Heli-Expo (Booth No. C3504). LMB designs and manufactures both AC (50/60 Hz, 400 Hz and wild frequency) and DC (12-300 VDC) brushless motors used in fixed- and rotor-wing aircraft, as well as in ground military vehicles. The company offers more than 1,000 shelf-qualified products, while its engineering expertise capabilities enable it to quickly design and build these components to meet specific requirements that meet Mil STD 810/461 and RTCA DO-160 standards.
Duncan Aviation is authorized to modify the Universal Avionics UNS-1C flight management system to include an extended-life battery. A Duncan Aviation tech rep told AIN, “The original battery voltage was 3.6 volts and the new one is 3.93 volts. While the voltage increase in this lithium watch-type battery seems small, it makes a big difference. Previously a battery warning meant a day or two at most until you had a databus failure locking up the entire system. The new battery gives you about three months [after a warning],” he said.
