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.
Major changes are happening in the world of 3D printing and additive manufacturing materials, machines, and software. If the industry -- and the design engineers and OEMs it serves -- are to grow, all three areas must become much more tightly integrated.
Americans spent more than $60B on their pets in 2015. Folks are definitely spending their money on more than dog food. We’re spending on things like dog spas and fancy toys, and as you can imagine, the wearables market is becoming well represented here.
