Boeing earlier this
week wrapped up the second phase of gauntlet testing on its path to get the 787
Dreamliner to first flight, including tests on about one week's worth of operations
on the airplane along with hundreds of discrete test conditions.
During the testing, pilots and engineers simulated multiple
scenarios commanding all 92 airplane systems as if the aircraft, designated the
ZA001, were in flight, including power, avionics and flight controls. In his blog
journal of the 787's path to flight, Randy Tinseth, vice president,
marketing for Boeing Commercial Airplanes, provides a description of what the
"intermediate gauntlet" entails. Essentially a series of test scenarios, the
gauntlet puts the ZA001 through its paces just as if it were in flight, even
though it's still on the ground, Tinseth says. Pilots man the controls
during this test period, and a team of engineers sit at workstations in the
back of the plane. All the crew is on board for the duration of the "flight,"
Tinseth says, and the testing goes as far as to serve meals on board and
ensure that lavatories are working.
The test scenarios, which include long-duration standard
flights as well as simulations of single and multiple systems failures during
flights, are run day and night. Once the aircraft "lands," Tinseth says there's
even a crew waiting to clean up, inspect and refuel and restock the airplane
just as it were a real flight.
"The team has done an incredible job supporting an exhaustive test
regimen," said Scott Fancher, vice president and general manager of the 787
program, in prepared remarks. "I couldn't be more proud. We will continue to
take a hard look at the results, make adjustments and finish up our testing so
we can get to first flight."
UK-based Plastic Logic and French company ISORG have created what the pair tout as a first in flexible printed electronics: a large area, conformable, organic image sensor printed on plastic.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
