Retired Boeing 747 to become testbed for revolutionary new engines

(CNN) — When airplanes retire, they get transformed into everything from hotels to underwater art installations.
One Boeing 747 has a slightly less glamorous but nevertheless exciting future path. After 20 years soaring through the skies in Qantas livery, it's been recruited by Rolls-Royce's aerospace operations to start a new life as a testbed for futuristic engines.
The aircraft's final commercial flight was from Sydney to Los Angeles, and it's now based at AeroTEC, a flight center just outside Seattle. Here, this Boeing 747 is set to be transformed during a two-year-long, $70 million process, before helping to launch the next generation of Rolls-Royce jet engines.
The airplane flew more than 70 million kilometers over the course of its Qantas career, carrying some 2.5 million passengers.
As a flying testbed, the airplane will trial commercial and business engines at super fast speeds and high altitudes, operated by a crew of specialist test pilots.
The aircraft will join forces with Rolls-Royce's existing flying testbed, another Boeing 747 that's completed 285 test flights and counting.

New life

A mock-up image of how the aircraft will look when it's modified depicts the Boeing 747 testing the upcoming UltraFan engine, which the aviation company says will "redefine the world of jet engines."
The fan engine looks pretty big compared to the aircraft's standard power units.
"It's a really big fan, about 140-odd inches, compared to say, XWB that's got an 118 inch diameter," Caroline Day, head of marketing, strategy and future programs at Rolls-Royce, tells CNN.
On a visit to the UK Rolls Royce Aerospace factory in Derby, England, Day tells CNN Travel the company is building a number of UltraFan engines to test.
"That program is significant, there's hundreds of people working on it, because we want to get it ready for the back end of the next decade," she confirms.
The team are determined that the new engine will be more fuel efficient and safe and smooth.
As a testbed, the former Qantas airplane will be outfitted with instrumentation and systems allowing it to take measurements of engine performance while it's in the air.
"This airborne laboratory will enable the development and certification of new, highly advanced engine technologies designed to increase efficiency and minimize environmental impacts," said AeroTEC president and founder Lee Human.
"Our engineering, modification, and test teams in Seattle and Moses Lake are already hard at work preparing to bring Rolls-Royce's vision to reality."
