CFM International is including a contrarotating ducted fan engine in studies of concepts that might provide the quantum leap in fuel efficiency, noise reduction and emissions being demanded for the next generation of single-aisle aircraft.
Controversy continues to swirl around the FAA’s September 2005 aircraft thermal and acoustic insulation regulations, which went into effect in January. The agency amended the original regulations after discovering that the wording implicated a much broader range of components than intended.
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.
Canada's private, user-fee-based ATC system–Nav Canada–believes that general aviation operators are double-charged for use of Canada's aviation infrastructure and that fuel excise taxes should be reduced.
Skyrocketing jet fuel prices did almost nothing to slow down high-flying business jet travelers, who collectively took to the skies in record numbers this year, according to industry statistics. Now that crude oil prices are falling, analysts predict economic growth will further boost the use of business jets by corporations and the well-to-do.
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.
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.
With fuel prices at noticeably higher levels and Stage 4 noise requirements proposed to take effect next January 1, industry and government are working furiously on ways to make turbine engines even more efficient, while further reducing emissions and noise output. NASA is leading the charge, with plenty of help from the engine manufacturers themselves.
Inspectors waded through flooded refineries and helicopters passed over wounded drilling rigs in the Gulf of Mexico early last month, as oil companies struggled to assess how long it would take to recover from the effects of Hurricane Katrina.
When engine maker Pratt & Whitney opened its first machine shop in a tobacco warehouse in Hartford, Conn., 80 years ago last month, former Wright Aeronautical president Frederick Rentschler probably could not have imagined how popular, and ubiquitous, the company’s engines would become.
