Rocket Engineering of Spokane, Wash.–the company involved in the Piper Malibu JetProp DLX Pratt & Whitney Canada PT6A conversion–is at it again. This time Rocket has been quietly working for the past two years on a P&WC PT6A-35-powered Beechcraft Duke BE60 conversion.
Deliveries of new turbine business airplanes in the first half of this year increased by more than 31 percent compared with the same period last year, according to the latest shipment report from the General Aviation Manufacturers Association (GAMA) released Thursday evening. The report shows that OEMs delivered 100 more airplanes (87 jets and 13 turboprops) in the first six months of this year than in the same time last year.
The FAA issued an emergency Airworthiness Directive last month to all Robinson R22 owners and operators, calling for them to carry out immediate checks to assess the serviceability of their main rotor blades.
As every pilot and mechanic knows, high temperatures are the bane of any engine. But as engineers strive to design smaller, more powerful turbine engines by adding compressor stages, the compression ratio goes up and so does the temperature of the ram air. At a compression ratio of about 20 to 25, ram-air cooling becomes inefficient. The solution, researchers believe, lies with cooling the air before it goes into the combustor.
Honeywell’s small heavy fuel engine (SHFE), in development since 2003, “will change the game for turboshaft engines in the future,” predicted Ron Rich, the company’s director of advanced aerospace technology.
One million hours equals more than 114 years, 11.5 decades or nearly 42,700 days. No matter how you describe it, one million hours is a lot of time, and Bell said its 407 turbine single achieved this milestone late last year. The FAA certified the 407 in February 1996, and today there are 548 of them operating worldwide.
Boeing’s ability to use the same engine for the 737-900ER as it uses on the standard -900 undoubtedly helped the company justify its investment in the project, but that doesn’t mean the newest 737 won’t benefit from new powerplant technology.
Bell Helicopter of Fort Worth, Texas, and Urban Aeronautics based near Israel’s Ben Gurion Airport will unveil today the X-Hawk, an innovative vertical-lift aircraft that could create a new class of civil and military powered-lift vehicles. A full-scale mock-up of the twin-turboshaft X-Hawk is on display in Bell Helicopter’s aircraft covered aircraft static display (No. OE1, next to the Bell and Bell Boeing chalets).
Honeywell’s turbine engine folks are poised for show and tell about something new from something old–the time-tested TFE731 turbofan family–and something a lot newer: advanced technology aimed at developing a state-of-the-art engine in the 10,000-pound-thrust class.
Dallas Airmotive is opening a new 22,600-sq-ft warehouse at its Forest Park turbine engine repair and overhaul facility in Dallas.
