Edwards AFB CA (SPX) Apr 18, 2016
null NASA's goal of developing a quiet supersonic aircraft is another step closer following a pair of successful first flights in a series demonstrating patent-pending Background Oriented Schlieren using Celestial Objects (BOSCO) technology, effectively using the sun as a background in capturing unique, measurable images of shockwaves. Improved image-processing technology makes it possible to c

MH370: Debris found in Mozambique 'almost certainly' from missing plane, investigators say



Two pieces of plane debris found on the coast of Mozambique are "almost certainly" from missing Malaysia Airlines flight 370, investigators have said.

The two pieces of wreckage, one found on 27 December 2015 and the other found 135 miles away on 27 February this year, were confirmed to have come from the missing plane after a long investigation from the Australian Transport Safety Bureau (ATSB).

Start your engines…First full GE9X engine begins testing



April 11, 2016

PEEBLES, OH--Ground testing in underway on the first full GE9X development engine, which is the world’s largest commercial aircraft engine, at GE Aviation’s Peebles Testing Operation in Ohio. The GE9X engine will power Boeing’s new 777X aircraft.

“The entire GE9X team—from engineering to sourcing to supply chain to development assembly—devoted countless hours to enable this achievement to occur,” said Bill Millhaem, general manager of the GE90/GE9X engine programs at GE Aviation. “The ground testing will generate data on the full engine system and aerodynamic performance, mechanical verification, and aero thermal system validation.”

"We would like to convey our congratulations to the GE team for its achievement of this milestone,” said Bob Feldmann, Boeing 777X vice president and general manager. “GE's commitment to technology maturation throughout the GE9X development program continues to deliver results for the 777X program. We look forward to working together with GE to deliver this great airplane to our customers.”

Maturation testing of the GE9X engine began about five years ago and has progressed from component-level all the way to the first full engine to test (FETT). FETT brings all the GE9X technologies together to demonstrate their operability as a complete propulsion system.

Compared to other engine programs, the GE9X FETT happened earlier in the development process, just a mere six months after the engine design was finalized. This timing assures all learnings from FETT will be captured in the certification engines. Next year will be a busy year for the GE9X program with the start of certification testing and flight testing on GE Aviation’s flying test bed. Engine certification is anticipated in 2018.

With almost 700 GE9X engines on order, the GE9X engine will be in the 100,000 pound thrust class and will have the largest front fan at 134 inches in diameter with a composite fan case and 16 fourth generation carbon fiber composite fan blades. Other key features include; a next-generation 27:1 pressure-ratio 11-stage high-pressure compressor; a third-generation TAPS III combustor for high efficiency and low emissions; and CMC material in the combustor and turbine.

IHI Corporation, Snecma and Techspace Aero (Safran), and MTU Aero Engines AG are participants in the GE9X engine program.

An inflatable flying camera for the drone-averse [feedly]

With all the furore about drones today, it's easy to forget that blimps once ruled the skies over sporting events. But one company believes that big airships still have plenty to offer in this area, so has developed an aerial platform that carries broadcast gear and won't wreak havoc should it come crashing to the ground.

UK civil air display review: final report Shoreham air disaster of August 2015



On 22 August 2015, a privately-operated Hawker Hunter (G-BXFI) which had just commenced an air display routine at Shoreham UK, after positioning from its base at North Weald for the purpose, crashed into traffic on a nearby and very busy main road in day VMC. The aircraft broke up on impact and its destruction was completed by intense fires in parts of the wreckage. Eleven road users were killed and the pilot was seriously injured.
