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.
Pratt & Whitney Canada (P&WC) has started running the PW617F engine. This is the latest member of its 900- to 1,300-pound-thrust PW600 family and is set to power Embraer’s Phenom 100 very light jet. The new turbofan was run for the first time on June 29, P&WC president Alain Bellemare told Aviation International News exclusively on the eve of the Farnborough show, saying that the engine was “going well”.
After operating below the radar for several years, Maverick Jets, now headquartered in Jackson, Wyo., revealed it is working on a next-generation Maverick Leader called the SmartJet. The five-seat, twin-turbofan, all-composite SmartJet has a planned mtow of 4,160 pounds, an empty weight of 2,150 pounds, a normal cruise speed of 277 knots at 22,000 feet and a max range of 1,250 nm.
With aircraft being pushed toward the edges of their flight envelopes here in the daily aerial displays at Farnborough International, their crews need real certainty that all is well with the engines. Helping to give them this assurance is local company Jet-Care which is providing its patented oil and engine debris analysis service for all aircraft here at the show this week.
Recently appointed Pratt & Whitney president Steve Finger is in no doubt about his company’s position in the global marketplace. “The Eagle is everywhere,” he said. “We’re the only engine manufacturer with a complete portfolio spanning civil, military, business and rocket engines along with maintenance, repair and overhaul.” The Eagle refers to the defining symbol of the U.S.’s oldest turbine aircraft engines manufacturer.
Citation modification specialist Sierra Industries last week received an STC for its Stallion conversion, a Citation 500/501 powered by Williams FJ44-2A turbofans in place of the twinjet's original P&WC JT15Ds.
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.
Piper Aircraft president and CEO Jim Bass yesterday unveiled the company’s next generation aircraft–the single-engine, six-seat PiperJet, an airplane priced at just under $2.2 million that adds another serious player to the market for very light jets.
On the eve of NBAA 2006, Honeywell made it official that it is developing technology and hardware toward launch of a 10,000-pound-thrust turbofan engine for super-midsize to large business jets.
