Rolls-Royce Unveils New Jet Engine … Made of Legos

rollsroycelego

Airplane engine maker Rolls-Royce unveiled the newest version of its Trent 1000 at the Farnborough International Airshow this week. It doesn’t produce any thrust, but it is a fairly accurate, half-scale model of the real thing. And it’s made entirely of Legos – 152,455 of them, to be exact.

The Lego engine weighs 675 pounds and has a fan diameter of nearly 5 feet compared to the 12,710 pounds and just over 9-foot diameter of the real engine. The Lego model is a cutaway of the Trent 1000 and shows the inner workings of the engine, complete with the complex fan blades up front that provide most of the thrust, to compressor blades and a combustion section can be seen in plastic brick detail.

The real Trent 1000 is one of two engines – along with the General Electric GEnx-1B – available on the Boeing 787 and powered the Dreamliner we had a chance to fly.

Rolls-Royce Chief Scientific Officer Paul Stein said the company built the engine to inspire the younger generation. “We are very pleased some of our own graduates and apprentices have contributed to building it, ensuring it is as realistic as possible,” Stein said in a statement. “We hope that this representation of our technology will help to enthuse and inspire the potential scientists and engineers of the future about the career opportunities they could pursue.”

The Lego model isn’t a bad way to make a few headlines during a crowded airshow, either. The entire engine is comprised of more than 160 separate engine components and took a team of four people eight weeks to complete (video below). The big question for a lot of kids will be, How much will the kit cost? It does look like there were quite a few specialty parts, might be worth sticking to simpler, but still very cool Lego aircraft designs.

The English company has a long history in aircraft engines dating back to World War I, and Rolls-Royce traces its jet engine roots back to work with one of the co-inventors of the jet engine, Frank Whittle, in the 1940s.

First Airbus A350 Hitches A Ride To the Factory

The forward fuselage of the new Airbus A350 XWB composite airliner has been delivered to the factory. This particular airframe – MSN5000 – will never fly, but it’s still a milestone for Airbus’ first airliner made largely of composite materials.

MSN5000 will be used for ground testing to confirm the strength of the composite paneled airframe and wing structures. It’s in line just ahead of MSN001, which is slated to be the first flying airframe.

The wide-body airliner is slightly larger than the Boeing 787 Dreamliner, but instead of having a large composite tube for a fuselage, the A350 uses composite panels attached to an aluminum frame. The plane will use a composite wing with a span of more than 219 feet, compared to 197 feet for the 787.

Based on size and seating, the A350 competes more closely with the Boeing 777. That said, it’s often compared to the Dreamliner because of its extensive use of composite materials. Like the Dreamliner, the new Airbus will provide substantial fuel savings thanks to the new designs and new engines.

Because the various A350 components are manufactured throughout Europe, Airbus uses a heavily modified A330 known as the “Beluga” to transport sections of the wings and airframe.

The forward fuselage of MSN5000 is expected to be joined with the center fuselage section early next year in Toulouse, France. Like other new designs, the finished airplane will be tested and tortured to validate the strength and longevity of the structures and systems.

Like the Boeing 787, the A350 has been hit with some delays, though the first flight of an A350 is expected in 2014.

Boeing 787 Sets Round-the-World Record

It’s been a busy week for Boeing 787 pilots, who kicked off a world tour in one Dreamliner and circumnavigated the globe in record time flying another.

To bolster the Dreamliner’s reputation, Boeing is sending the refurbished ZA003 flight test airplane on a six-month global tour that started in China and stops next in the Middle East and Africa. Cooler still, a second test airplane, ZA006, went around the world this week in less than 43 hours.

ZA006 departed Boeing Field in Seattle at 11:02 a.m. Tuesday and landed in Dhaka, Bangladesh, setting a distance record for its weight class. The 10,337-mile flight was the first leg of ZA006′s journey.

The plane stayed in Dhaka for two hours to refuel before the 13 people aboard took off for home. After another 9,734 miles, the flight landed at Boeing Field 42 hours and 27 minutes after leaving Seattle.

The trip netted two records. The first was absolute distance for an airplane in the 440,000- to 550,000-pound weight class. Boeing broke a record the Airbus A330 set nine years ago. The second record was for the shortest time around the world in the same weight class. Granted, ZA006 was the first plane in its weight class to attempt the record, so it literally was no contest.

Boeing recently sent the first 787 Dreamliner, airframe ZA001, into retirement. It is expected to eventually land in a museum.

Boeing has delivered two 787s to All Nippon Airways and the airplanes are currently flying passengers on domestic routes within Japan. International 787 flights are expected to begin early in the new year.

Feds Sign Off on Boeing’s 787 Dreamliner

EVERETT, Washington — The flight testing is done, the Federal Aviation Administration has issued its approval and as of today Boeing can say the 787 Dreamliner is certified to carry passengers.

The FAA presented Boeing with a type certificate and production certificate for the innovative composite airliner during a grand ceremony at Boeing’s factory north of Seattle. The pieces of paper mean the Dreamliner can begin commercial service, and they represent the culmination of several billion dollars of investment for the aerospace giant and almost as many headaches.

Boeing attempted a grand experiment with the Dreamliner, one that proved far more difficult to execute than anyone imagined. The 787 project took more than three years longer than expected, and the delays cost Boeing untold amounts of money in lost sales. Still, the company has orders for more than 800 Dreamliners and hopes customers will find the airplane was worth waiting for.

“This is going to be an airplane that changes the game,” CEO Jim Albaugh told the crowd gathered around the first 787, airplane ZA001. “Once our customers get this airplane, I think they’ll forgive us for the fact that it was a little bit late.”

The hard work is only beginning, and more headaches may be ahead. Boeing has shown the composite airplane works as promised. Now it has to prove it can build Dreamliners quickly and efficiently and see a profitable return on its investment.

“This doesn’t magically open up the flood gates and release a torrent of cash,” says Richard Aboulafia, an aerospace analyst with Teal Group. “If anything, the financial part could get worse as they try to ramp up production. It’s going to be a very difficult 18 months.”

Boeing 787s await finishing and delivery to customers at the company’s Paine Field facility. The modified 747 known as the Dreamlifter is at right.

The flight testing of the 787 program has gone fairly well since the Dreamliner’s first flight in December, 2009.

There have been a few hiccups, including an in-flight fire and quite a few delays, but Boeing has shown the 787 will perform as claimed. This was key to securing sales, because Boeing claims the 787 is about 20 percent more fuel efficient than similar aircraft and will therefore save airlines a lot of money.

The fuel efficiency comes thanks to new engines from Rolls Royce and GE, along with improved aerodynamics, primarily in the wing. The engines with their serrated cowlings are also dramatically quieter than existing airliners. In fact, they’re so quiet that during testing, many have commented it sounds like the engines are shut down entirely.

The composite fuselage should make passengers more comfortable. It allows for bigger windows, as well as a lower cabin altitude and higher humidity.

But building the 787 has been anything but smooth. Parts shortages, design defects (including a problem with how the wing joined the fuselage) and a global supply chain caused several delays.

Boeing took a huge risk when it decided not only to design and build an entirely new airplane, but to come up with a new way to design and build that airplane. In an unusual move, the company outsourced the design and construction of major components to firms in countries around the world. Many point to that as the cause of many delays, which ultimately made the plane three years late.

But Aboulafia says the real problem was Boeing let outside firms do too much design work.

“Outsource production,” he says. “Don’t outsource design.”

All the 787s completed so far have been assembled from complete subsystems on an assembly line in Everett, Washington, alongside the 747, 767 and 777 lines. The company also opened a second 787 assembly line in South Carolina where airframe number 46 is currently being put together.

But unlike other Boeing models, in which much of the manufacturing occurs in Everett, the 787 is assembled from subassemblies manufactured in several countries and flown to Washington in modified 747s.

A short list of the parts built outside Everett include fuselage sections made in Italy, Japan, South Korea and the United States. Floor beams are built in India. Wing sections come from Japan. The doors and landing gear are made in France and Sweden. Portions of the tail are made in Italy and South Korea.

In addition to distributing some of the cost and risk, the global supply chain was also a way to make friends in countries where Boeing wanted to sell the 787.

A model of a Boeing 787, presented to FAA Administrator Randy Babbitt, stands in front of ZA001, the first 787 ever built.

The process hasn’t gone smoothly, and the challenge now is build airplanes fast enough to keep customers happy. Boeing has orders for more than 800 Dreamliners, and will have to build them quickly and efficiently enough to start making money. List price for the current 787 is $185.2 million. But it is widely understood that airlines receive various discounts on orders.

“Boeing has to start building this plane for the price they charge,” Aboulafia says, and “it might take the majority of the decade” for Boeing to accomplish that.

When FAA Administrator Randy Babbitt handed Albaugh the type certificate, the 787 chief project engineer Mike Sinnett held it over his head like a coach hoisting the Super Bowl trophy (below).

The type certificate from the FAA means the airplane has been tested and meets all of the federal requirements for a passenger carrying aircraft. The agency has approved the airplane as a certified airplane suitable for its intended use. But as Babbitt noted, the production certificate is no less important, because it means Boeing can actually produce and sell the 787 as well.

The eighth airplane off the assembly line will be delivered to All Nippon Airways on September 26 and is expected to enter passenger service in Japan weeks later.
