The FAA has issued an update to its 2010-2011 Ground Deicing Holdover Time Tables and Guidance on its website. The document contains a revised listing of the lowest operational use temperatures (Lout) for anti-icing fluids, which were supplied to the agency and Transport Canada by the fluid manufacturers.
A bilateral project between NASA and German aerospace research center DLR is expected to focus on the role rotor tip vortices play in helicopter noise by recording vortex velocity fields and rotor-blade deformations by using a test stand with a variety of high-speed cameras, lasers and LEDs that will make the vortices visible. Eventually research will progress to actual helicopters.
The FAA has issued a final rule for an Airworthiness Directive for the Embraer Phenom 100 S/N 50000005 through 50000118, 50000120, 50000122 through 50000126, 50000128, and 50000131, certified in any category. The AD says it is prompted by failures of the flow control shutoff valve in the closed position.
Aerion, based in Reno, Nev., is at Booth No. 6202 in NBAA exhibit Hall C to describe preliminary results from the latest round of flight tests of a NASA F-15B on the road to what it envisions as the worlds' first supersonic business jet (SBJ). The tests during July and August in collaboration with NASA's Dryden Flight Research Center achieved a top speed of Mach 2.0.
JetBed (Booth No. 1135) is expanding its line of inflatable aircraft beds. CEO Gary Bosstick told AIN that the company will soon launch products for Embraer executive jets and Pilatus PC-12 turboprops.
Business jet engine programs this year seem to be moving slowly, with little progress to report. Some–like the Snecma Silvercrest–have not been officially launched yet and are still looking for an application. Most news comes from derivative engine programs at Honeywell, Pratt & Whitney Canada and Williams International.
Rolls-Royce is putting all its cards on a new engine to power future single-aisle aircraft and told AIN that as far as it is concerned, “the numbers do not stack up” for re-engining either the Airbus A320 or Boeing 737.
A U.S. district court ruling on June 17 rejected the claim by plaintiff Excel-Jet that the June 22, 2006, takeoff crash of the experimental single-engine Sport-Jet was caused by wake turbulence.
The June 16 first flight of the fifth Boeing 787 Dreamliner (ZA005) also marked the first time a pair of GE Aircraft Engines' GEnx-1B turbofans powered an airplane to altitude on their own. Captains Mike Bryan and Mike Carriker flew the airplane for three hours and 48 minutes, and reported no anomalies.
The Boeing X-51A WaveRider hypersonic vehicle, powered by a Pratt & Whitney Rocketdyne scramjet engine, achieved aviation history this week by making the longest ever combustion ramjet-powered supersonic flight. During its first jaunt, the craft reached 70,000 feet and an approximate speed of Mach 5 on a 200-second flight over the Pacific Ocean on May 26 at 10 a.m. before it was purposely crashed into the water.
