Boeing Business Jets and Airbus Corporate Jetliners could benefit from new engine technology planned to enter service on the next-generation 737 and A320 airliners from which they are respectively derived. CFM International is working on an advanced turbofan, targeting a 16-percent cut in fuel burn that could bring greater efficiency to these and other new bizliners.
Hyannis, Mass.-based Prime Turbines has been acquired by Avatas Aerospace. The FAA-certified repair station, which specializes in the PT6 turboprop, conducts hot-section recertification, power section repair, gas generator repair, fuel nozzle overhaul and exchange, and bleed valve overhaul and exchange.
Prime is an authorized distributor of FAA Parts Manufacturer Approval parts for PT6 hot sections.
The in-development geared turbofan (GTF) has been attracting most of the headlines at engine manufacturer Pratt & Whitney lately, and it does indeed promise to make a large leap in powerplant efficiency and environmental friendliness when it enters airline service in 2013.
The FAA has adopted and/or proposed a series of Airworthiness Directives (ADs) that will affect operators of Honeywell ALF502/507 and TFE731 engines and Sundstrand APUs. ALF502L-2 and L-2C engine compressor discs may have had too much disc balance material removed, which could cause premature fracturing of the disc.
McDonnell Douglas MD 600, San Clemente, Calif., Feb. 19, 2009– The U.S. Customs and Border Protection MD 600 autorotated to a forced landing on the beach after the crew heard a loud “bang” and warning lights came on. A main rotor blade severed the tail boom. Examination of the engine showed that both engine chip detector plugs were contaminated with metal particles. The No. 4 turbine wheel was damaged.
Williams International last month completed extended testing of a coal-based, alternative fuel in an FJ44-3 engine. Two thousand gallons of the synthetic fuel powered the turbofan for 118 cycles over 21 hours. According to Williams, the fuel, which was developed by a team at Penn State University with help from Intertek-PARC and Duquesne University, performed well.
Engine manufacturer Pratt & Whitney Canada (Booth No. 624) remains committed to developing new engine products whatever the impact of the global downturn on a changing industry, according to president John Saabas. He told HAI Convention News that last year had been “a peak year” for the Canadian manufacturer.
The Honeywell/Pratt & Whitney joint-venture Advanced Turbine Engine Co. (ATEC) successfully completed the preliminary design review by the U.S. Army Aviation Applied Technology Directorate and other government customers for the advanced affordable turbine engine (AATE) technology demonstrator program.
Savings of up to 40 percent on jet fuel for the Rolls-Royce 250 turbine-engine family? That is the prospect offered by Frontline Aerospace, said company CEO Ryan Wood in describing an emerging aviation technology called gas turbine recuperation.
When it issued Eclipse 500 Airworthiness Directive 2008-24-07, which becomes effective today, the FAA asked for comments from operators. The AD limits the Eclipse 500 to a maximum pressure altitude of 37,000 feet due to “several incidents of engine surge” of the jet’s Pratt & Whitney Canada PW610F-A engines. The surge is due to carbon buildup on the static vane during high bleed flow conditions.
