The 560-pound-thrust DGEN380 turbofan engine recently made its first run in Tarnos, France, start-up company Price Induction announced. So far, the engine’s stability and vibration level are satisfactory, the company said. The 50 hours of the first test segment are being spread over this month.
Canada’s National Research Council, NRC Aerospace (Hall 4 Stand C17a), is gathering detailed wake turbulence data with a specially equipped aircraft. NRC’s CT-133, a former military trainer, has just completed instrument test flights. Researchers are focusing on en route wake turbulence behind commercial aircraft, which seem to be more dangerous than expected.
Boeing is using Qinetiq’s low-speed wind tunnel for continuing evaluation of the 747-8, the latest iteration of the world’s first twin-deck widebody jetliner now midway through its fourth decade. The facility is located here at Farnborough, on the north side of the airfield.
Sensor expert Auxitrol (Hall 1 Stand B11) is benefiting from rapid production ramp-up in several engine programs. Products from the Bourges, France-based company are incorporated in the Pratt & Whitney Canada PW610F and PW615F engines, which power the Eclipse 500 and Cessna Citation Mustang very light jets, respectively.
Aviation Technology Group has added Goodrich Aircraft Interior Products, Kavlico, Moritz and Parker Aerospace to its list of suppliers for its Williams FJ33-powered Javelin business jet and derivatives. Under the terms of the contracts, Goodrich will supply pilot seats, Kavilco the throttle quadrant, Moritz the power distribution system and Parker the hydraulics.
For the last few years, much of the buzz in the turbine engine world has focused on the new small powerplants from Pratt & Whitney Canada, Williams and the Honda-GE Engines joint venture to propel the emerging class of very light jets. Now the spotlight has shifted somewhat, to advanced technology aimed at developing state-of-the-art engines in the 10,000-pound-thrust class for a new breed of large business jet.
Aviation Partners (Booth No. 876) is expanding its reach in the winglet modification market with new Hi-Mach Super Critical winglets optimized for the high-speed cruise regime. To date, the company’s Blended Winglets have helped operators enjoy lower fuel burn, higher initial climb altitudes and longer range while flying at long-range cruise speeds. The new Hi-Mach winglets have the same effect, but at Mach 0.80 and above.
Gulfstream reported that its Quiet Spike sonic-boom mitigator successfully achieved supersonic flight on October 20. The OEM has been flight-testing the structural integrity of its Quiet Spike since mid-July. Mounted on the nose of a NASA F-15B and flown at Mach 1.2, the Quiet Spike operated as designed. It extended to its maximum length of 24 feet and performed as expected during the 1.5-hour test flight.
Engine manufacturers are gearing up for development programs aimed at bringing new generations of 10,000-pound-thrust turbofans to business aviation. Silvercrest, the first of Snecma’s new family of such engines for midsize to large business jets and 40- to 60-seat regional airliners, makes its world debut here with its new name and newly revealed specs.
The horizontal distance currently required between lighter and heavier aircraft to avoid wake turbulence might have to be doubled for smaller aircraft flying behind the new Airbus A380, according to preliminary findings of the International Civil Aviation Organization (ICAO).
