Bombardier Aerospace recently completed a non-temperature-restricted bleedless auxiliary power unit starting test, following a 10-hour cold soak at -40 degrees F and using a starter/generation system and lithium-ion battery system. The Safran Microturbo e-APU system included a starter generator and power electronics from Thales and a Saft Li-ion battery system. The prototype equipment was designed for business jets, Bombardier said. The tests were conducted at the Safran Turbomeca cold-chamber facility in Pau, France.
Parker Aerospace is here at FIA 2014 (Hall 4 Stand A18) highlighting a variety of technology developments and improvements in its customer support provisions.
Rotron, a Gilo Industries Group company, announced here at the Farnborough Airshow the launch of what the company calls the first series of commercial off the shelf (COTS) heavy-fuel engines in the 20-60 hp category.
Camarillo, California-based Merex Group (here with subsidiary Kellstrom Defense in Hall 3 Stand D12) has announced the acquisition of specialized tooling and inventory to manufacture spares for the F-5, T-38 and F-16 fighters. This gives Merex the capability to produce the wing leading and trailing edge, vertical stabilizer and horizontal stabilizer as replacement parts. Sierra Aerospace of Simi Valley, California, sold the surplus equipment. The Merex Group will make additional investments in 3D computer aided design to improve the dimensional accuracy and quality of the final product.
Unison Industries (Hall 4 Stand C14) has launched a new high-energy, high-temperature turbine engine ignition system designed to meet the “growing trend of climbing engine temperatures and combustion pressures.”
The Acclimate ignition system features solid-state electronics, with exciter performance that can vary depending on specific combustion and environmental requirements, according to Unison. This helps optimize ignition performance and overall system life, the company added.
When Gulfstream Aerospace of Savannah, Ga., unveiled the G650ER at EBACE, the company focused on the aircraft’s extended range of 7,500 nm, which makes it the world’s longest-range business jet (not including private airliners).
Snecma recently started flight-testing its Silvercrest turbofan on a modified Gulfstream II, a Snecma senior executive confirmed last week. AIN understands that the trials are taking place from Sierra Industries’ base in San Antonio, Texas. The maiden flight had been postponed several times but the delay is not expected to have any effect on the engine’s certification, planned for next year. The Silvercrest will power the Dassault Falcon 5X and Cessna Citation Longitude.
Driven by the ambition to become world’s third largest turboshaft engine manufacturer after General Electric and Pratt & Whitney, France’s Turbomeca is pressing to establish a Russian partnership to develop and coproduce a new 3,000-shp engine based on the existing RTM322 powerplant and using the new Tech3000 core.
Safran subsidiary Microturbo’s new e-APU60 auxiliary power unit received certification from the U.S. Federal Aviation Administration last month. It achieved European approval in May last year.
New engines planned by Rolls-Royce (R-R) reflect recent powerplant trends, including steadily increasing propulsive efficiency obtained with larger-diameter fans, higher bypass ratios and smaller engine cores. The engines could power updated contemporary widebody platforms, with R-R civil large engines president Eric Schulz confirming “very live” discussions with Airbus. “If it decides to re-engine the A330 or A380, we will be here to provide support,” he said during a pre-show briefing.
