A switch from composite to titanium for the inner walls of the thrust reversers on the Boeing 737 Max has allowed designers to increase the fan diameter in the airplane’s CFM International Leap-1B turbofans without a proportional increase in the size of the nacelle. The relatively minimal growth of the nacelle means Boeing could keep its original plans for coping with the small amount of ground clearance margin available while optimizing thrust levels, explained 737 Max program vice president and general manager Keith Leverkuhn.
Russian accident investigators appear to be focusing on possible failures in the thrust reversers and/or brakes of a Red Wings Airlines Tupolev Tu-204 airliner that crashed into a Moscow highway after overshooting a runway at Vnukovo Airport on December 29. The aircraft was on a ferry flight from Pardubice in the Czech Republic with no passengers. Five of the eight crewmembers on board were killed, including the captain, first officer, flight engineer and two flight attendants.
Safran USA (Booth No. 2579) is flexing some considerable muscle here at the convention, showing a diverse role in the business aircraft market that stretches from nose to tail and wingtip to wingtip. Among the aviation products available from this global conglomerate are turbofan engines, nacelles, thrust reversers, landing gear, wheels and brakes, auxiliary power units, avionics, navigation systems, flight controls and wiring.
The search for answers continues into what caused the mid-afternoon landing overrun accident of a Gulfstream GIV at Le Castellet Airport (LFMQ), in France, on July 13.
All three crewmembers perished when their Gulfstream IV crashed on landing at Le Castellet Airport (LFMQ) in the south of France on Friday at 3:18 p.m. local time. The twinjet, registered as N823GA, was being operated by U.S. charter firm Universal Jet Aviation on a Part 91 repositioning flight from nearby Nice. There were no passengers aboard the aircraft.
Pratt & Whitney will offer its PW4170 Advantage70 engine for Airbus’s revamped, 240-ton max takeoff weight A330. “The Advantage70 is the benchmark on the A330 aircraft program in terms of fuel burn, operating costs, reliability and time-on-wing,” said Lou Quattrocchi, the U.S. engine maker’s vice president of commercial programs.
S.S. White Technologies (Hall 4 Stand A4) has been selected to provide flexible rotary shafts for the Pratt & Whitney PW1000G engine’s nacelle. The shafts will transfer power on the variable area fan nozzle (VAFN) and synchronize actuators on the thrust reversers. The U.S. company has already provided two flexible rotary shafts for the thrust reverser rig, and previously supplied two flexible shafts for the VAFN test setup.
Rolls-Royce and Aircelle have signed a service contract for the Trent 900 engine nacelles that will be fitted to British Airways Airbus A380s. The airline has ordered 12 of the type.
General Electric/Safran joint venture Nexcelle has successfully completed the test program for the thrust reverser on next-generation integrated propulsion systems (IPS).
While certainly some professional attendees at this year’s Farnborough International Airshow must know what a flexible rotary shaft is and what it can do, there’s a good chance that many, if not most, visitors do not. So, S.S. White Technologies, Inc. (SSWT), a first-time Farnborough exhibitor (Hall 4 Stand 4), is here to shed some light on its main product.
