If it didn’t become immediately apparent when Boeing began alluding to time frames that implied a replacement of the 737 might not materialize until 2020, the company’s recent revelations of a new set of design enhancements certainly erased any doubts that a so-called follow-on will have to wait until designers and engineers squeeze all the efficiency and comfort available from the existing narrowbody family.
In both engineering and visual terms, the open rotor is a huge departure from the turbofans that power today’s aircraft. As such, Rolls-Royce believes its market acceptance will involve a comprehensive understanding of the operational environment in which it will function.
Rolls-Royce’s development of an open-rotor engine for the next generation of midsize airliners has taken a giant leap forward after wind-tunnel tests revealed its design would comfortably meet current Stage 4 noise regulations.
Pratt & Whitney has (Hall 5 B20-B30) frozen the design configuration of the PW1000G geared turbofans for both the Mitsubishi Regional Jet and Bombardier C Series after finishing the final phase of demonstrator testing this past spring on an Airbus A340-600 testbed in and around Toulouse, France.
Brazilian search teams found more wreckage from Air France Flight 447 yesterday and today as evidence mounted that the Airbus A330 likely broke apart above the ocean while flying through a violent storm.
Bombardier’s plans to increase production of its commercial airplanes by 10 percent this year remain intact for the time being, notwithstanding Bombardier Aerospace president and COO Guy Hachey’s statement today that some customers have approached the company about possible delivery deferrals.
Boeing took a crucial step toward first flight of the 787 on May 21, when it executed the first all-electric start of a twin-aisle commercial jetliner and completed the Dreamliner’s first engine runs. During some 40 minutes of testing, the Rolls-Royce Trent 1000 turbofans operated at various power settings to ensure all systems perform as expected.
Boeing yesterday announced a series of planned improvements to its 737 line the company says will result in a 2-percent decrease in fuel burn and a marked upgrade in cabin comfort and utility.
An unapproved and improper procedure used by mechanics to manually start the left engine on an American Airlines jetliner on Sept. 28, 2007, probably caused a fire that forced an emergency landing, the NTSB determined today.
