First Bell 525 Delivery Slated for 2017

The 525 Relentless won’t be delivered to its first operators until 2017, Textron Chairman and CEO Scott Donnelly told financial analysts today in explaining the Bell Helicopter parent’s second-quarter earnings. The 525 first flew July 1; the manufacturer had aimed to get the super-medium twin in the air before the end of 2014. Donnelly said interest in the 525 is strong; in the second quarter, he said, Bell received 30 additional letters of intent from customers to purchase the fly-by-wire helicopter.

MH370 - Boeing: It`s probably ours

"Due to the state of the parts, it looks like a controlled forced landing"

MH370 search: Experts investigate Indian Ocean wreckage

  • 5 minutes ago

Malaysia has sent a team to the French Indian Ocean island of Reunion to determine whether debris which washed up there is from missing flight MH370.
The Malaysia Airlines Boeing 777 travelling from Kuala Lumpur to Beijing with 239 people on board vanished without trace in March 2014.
Aviation experts have said the debris looks like a wing component from a 777, known as a flaperon.
Malaysia Airlines said it would be "premature" to speculate on its origin.
There were 227 passengers on the flight, including 153 Chinese and 38 Malaysians.
"Whatever wreckage found needs to be further verified before we can further confirm whether it belongs to MH370," Transport Minister Liow Tiong Lai told reporters in New York where he was attending a UN Security Council debate for a separate Malaysian jet shot down over Ukraine.
"So we have dispatched a team to investigate on this issues and we hope that we can identify it as soon as possible," he said.

That Piece of Debris Won't Tell Us Where MH370 Crashed


A PIECE OF Malaysian Airlines Flight 370 might have washed up on a tropical island. If investigators do find that the piece belongs to the lost Boeing 777, it would answer a lot of questions. One question it will not answer however, is where the plane went down. 


Most non-conspiracy theories have put MH370's crash site somewhere in the vast, southeast Indian Ocean. If this is true, it would make sense that a piece washed up on Réunion Island, about 580 miles southeast of Madagascar, because the currents in that part of the ocean run generally west. But anything more than that is just too complicated. 


 "The problem is ocean currents have a lot of variation in them," says Colleen Keller, a senior analyst for Metron, Inc, a company that specializes in computational modeling. "Maybe if you were looking at a day you could trace a piece of wreckage back, but over the course of several seasons the only thing we can say is about the general direction of the currents." 


 For one, the Indian Ocean is vast, with seasonal currents. Those currents have eddies, those eddies interact, and their interactions create changes in the parent currents. All that swirling about makes it very difficult to untangle which currents the wing was bobbing around in. And that's not even counting the typhoons, tropical storms, and minor squalls that stirred things up. "It's just a washing machine of water that's not very predictable," says Keller. 


 And it's not just the computation of those swirls and squalls that's difficult. Those models are running mostly on assumptions. "Usually you come up with a baseline, then throw some buoys and catch some actual data, bring that back to the model, then go back and get more data," says Keller. 


 Even if this piece of debris doesn't solve the mystery of where MH370 crashed, it still might offer some closure for the victims' families if investigators confirm it belonged to the missing Boeing 777. "It can put to rest the idea that the airplane is still out there," says Keller. The Indian Ocean may be huge and mysterious, but at least it could be part of an answer.

A Russian helicopter pilot on a solo trip around the world was rescued on Monday morning after spending more than 30 hours alone on an ice floe after ditching his Robinson R22 helicopter about midway between Iqualuit and Greenland, in the Davis Strait. "It's wet. It's cold. He has some polar bear neighbors who are very interested in his whereabouts. He has quite a survival story," said Rear Admiral John Newton, of the Canadian Navy, who spoke to the press about the rescue. Newton said Sergey Ananov, age 49, had a life raft and a survival suit. "It was a very small target [for searchers]," Newton said. Rescuers were alerted when an on-board beacon indicated that the aircraft had descended to sea level and stopped moving, but then had to search for Ananov at sea amid clouds and fog.
Ananov used flares to signal his rescuers, and was down to his last one when it was spotted by a Canadian Coast Guard ship. Speaking by satphone from the Coast Guard ship, Ananov told CBC News he had a mechanical problem. "The belt that transfers the power from the engine to the gear was broken and the machine lost its power," Ananov said. "There are two valves, so one of them broke, and with one valve remaining the machine cannot fly horizontally." The R22 began to spin out of control, and he went "down, down, down." He tried to land on the ice floe, but lost control and crashed into the Strait. Taking along his life raft and supplies, he swam to the ice floe and put on his survival suit. Ananov had started the trip from Moscow on June 13, and already had crossed North America.

Malaysian MH370 - Parts found?

MH370: Is wreckage discovered off coast of Africa from missing jetliner?

Debris discovered on the coast of the island of Reunion could be that from the airframe of a Boeing 777, like the Malaysia Airlines jetliner which disappeared without trace last year



Airplane wreckage found off the coast of Africa could belong to missing Flight MH370, it has emerged.

The plane was flying from Kuala Lumpur in Malaysia to Beijing, China, when it is thought to have come down in the Indian Ocean on March 8 last year.
There were 239 passengers and crew - most of whom were from China - on board when it disappeared.
MH370 vanished from radar screens shortly after taking off from Kuala Lumpur.

Malaysia has officially declared the disappearance of the flight an accident and has said all 239 passengers and crew on board are presumed dead.
An international search operation in the Indian Ocean has yet to find any trace of the missing plane.
There have been several theories as to what might have happened to the aircraft after it disappeared from radar.

These include:
  • It went north heading towards ­Kazakhstan. Thai military radar seems to confirm the plane turned west, then north.
  • It went west and was flown to Diego Garcia, the British-owned island in the Indian Ocean that is let as a military base to America. Surrounding islanders claim they saw a plane low in the sky the morning Flight MH370 went missing.
  • It went south over the ocean off Australia, where the search has been concentrated.
Reunion is a territory of France in the Indian Ocean, several thousand miles from the international search zone.

Norsk in the news - 3D printing

Norsk Appoints Boley to Lead First US Industrial-Scale 3D Print Facility
Hønefoss, Norway based company Norsk Titanium AS (NTi) announced Sunday that it has appointed former Aerojet President, Mr. Warren Boley, Jr. to the Board of Directors in concert with Norsk's plans to spearhead the first industrial-scale 3D printing facility in the United States.
John Andersen, Jr., Executive Chairmen of Norsk Titanium referenced the experience of NTi's new leadership in a statement: "Warren [Boley] has a wealth of experience in aerospace and defense. His client-focus and drive for growth are uniquely suited to support NTi's expansion in the United States."
Mr. Boley has led additive manufacturing operations for the aerospace industry in past engagements. At Aerojet, he's led $1B in operations in manufacturing of propulsion devices. Aerojet used 3D printed technology to fabricate rocket engines in just three parts: the entire injector and dome assembly; the combustion chamber; and a throat and nozzle section.
NTi's state-of-the-art 3D printing facility is funded as a part of a private-public partnership, and it will cover a 200,000-square-foot factory area. According to Mr. Boley, the number and scale of 3D printers in the facility will continue to increase. Norsk uses Direct Metal Deposition (DMD) technology to produce high quality Titanium parts for industrial and aerospace industries.
The company announced in July that RTI International Metals, Inc. (NYSE: RTI), a supplier of titanium and specialty metals, has become an investor and partner. Direct Metal Deposition (DMD) is Norsk's patented process.

Norsk has plans to work with other companies to develop parts for the aerospace industry as well, and NTi is talking with Lockheed Martin Corp about building components for the F-35 fighter jet.

3Dprint.com's Michelle Matisons discusses the DMD process and RTI partnership in her post earlier this month. Proponents of 3D printing, or additive manufacturing, say it can cut the cost of titanium aircraft parts, which ordinarily cost seven times more than their aluminum counterparts. The process conserves more titanium and produces parts cheaper and in less time than traditional methods. 

Mr. Boley said the following about the new technology and NTi's manufacturing plans: "We're going to make history...this is part of the next industrial revolution. The project involved hundreds of millions of dollars of investment over the past seven to eight years. Its goal is to build large-scale components for commercial aircraft. To be part of the commercial introduction of a game changing technology that will drive affordability and speed of production in components for the commercial aerospace and defense sectors is an honor."

Norsk expects the U.S. Federal Aviation Administration (FAA) to certify the direct metal deposition process this year, leaving the individual parts to be approved by aircraft manufacturers. Mr. Boley says orders will be ready for launch by the first quarter of 2016.
