NASA engineers have completed tests on a device that opens the path for development of "all-electric" aircraft. Called the Electro-Hydrostatic Actuator, the device eliminates or minimizes airborne dependence on hydraulic, pneumatic, and mechanical systems. NASA tested the device on the left aileron of its F/A-18 Systems Research Aircraft without using the plane's central hydraulics. Taking its signals from the aircraft's flight-control computers, the device uses its electronics to trick aircraft computers into thinking a standard actuator is on board. Although the device contains a small amount of hydraulic fluid, it uses an electric motor to drive its pump. The force created moves the aileron. For many years, NASA, the Air Force, and the Navy have sought to eliminate heavy hydraulic systems in aircraft in favor of electrical "power-by-wire" systems for operating flight controls. The new device results from the Electrically Powered Actuation Design program of the Air Force.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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 discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
