Ever been on an airplane when the engines suddenly throttle up seemingly for no reason? It's probably because the pilot just switched from auto pilot (AP) back to manual control by disconnecting the AP and bringing the throttle levers back into the correct position. With SKF's new Automatic Throttle Control Unit, due out in two new planes in the coming months, that will no longer be an issue. "In older designs, the levers remained in a fixed position under auto pilot mode, so they were in the wrong place when the pilot resumed control. Further, the torque of the servo motors driving the levers was transmitted through a clutch, which made it very difficult for the pilot to override the automatic throttle without disconnecting it formally," says Product Manager Michel Giacomoni. "With our new system, the levers are driven by auto pilot and the pilot can override the AT through a force feedback system." Giacomoni notes that the force feedback comes from the corrective action of the AP computer, a modular avionic unit that gives the pilot feedback that the AT is engaged and that it is working correctly. Two new competitive aircraft will be the first to employ the system—the Gulfstream G200 (certified on July 2, 2004) and the Falcon 2000EX EASy, which is certified for delivery.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
