In all the talk about fuel-efficient engines, safety is rarely one of the principal issues discussed. But when you consider that fuel efficient engines tend to run much hotter and at higher speeds than conventional engines, safety is of paramount importance to the design engineer.
With that in mind, Test Devices Inc. has recently hired a new Chief technology officer, Hiroaki Endo Ph.D., to develop new ways to test components of future gas turbine engines — engines that will be more fuel-efficient but run hotter and expose components to more extreme conditions than current models.
Test Devices has successfully demonstrated the ability to simulate high order vibratory modes of airfoils in hot conditions. By applying extreme thermal conditions, centrifugal load and relevant vibratory excitations to blades and rotors, Test Devices can create test conditions that are representative of the real engine environment. Data from the tests helps engineers understand and validate the life and integrity of critical engine components. The test data can also help design engineers refine their assumptions, models and material selection.
I talk more about engine stress in high efficiency engines and about some of the specific testing being done at Test Devices in my accompanying video blog accessible by clicking on the image below.
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.
