By Dr. David Rizzo The F-35 Lightning II is an all-weather stealth combat aircraft built to perform warfare strike missions and electronic surveillance capabilities at speeds up to 1.6 Mach. Composites comprise 35% of the airframe weight, with the majority being bismaleimide, as well as some carbon nanotube-reinforced epoxy — which has a tensile strength…

The SAE’s WCX World Congress Experience was billed as where the engineering community convenes on mobility’s biggest hurdles from mass deployment of electric vehicles to developmental timelines for autonomous vehicles to understanding of global supply chain constraints impacting the automotive industry. We had a chance to peruse the WCX exhibits and kick the tires on…

By Charles Tschaggeny, Tschaggeny Design In 1984, Lockheed ceased production of the L1011 TriStar airplane and exited the world of commercial aircraft for good. For Lockheed, its latest passenger jet had been heralded as a technological marvel but was, in fact, a business disaster. The TriStar is a fascinating story that clearly illustrates fundamental concepts…

by Brig General (ret) Craig Baker, Acting COO & Cherif Chibane, CTO at WiGL Wearable medical devices play a vital role in healthcare for the military and civilians. Small, portable, and easy to wear, these devices assist first responders, war-fighters and patients with services ranging from physiological diseases like muscle disorders to neurocognitive disorders such…

Failure models and estimates of useful product life have grown increasingly more accurate thanks to a better understanding of how devices and materials degrade under stress. Leland Teschler • Executive Editor Back in the early 1970s, a college classmate of mine told an interesting story about his summer job running production-line tests for a manufacturer…

In this article, we detail how assembly, packaging, and machine-tool OEMs can keep senior plant personnel in charge of the most demanding and intricate tasks — and relegate everything else to pre-programmed work routines and automated workcells. Such approaches make copious use of cobots and augmented reality (AR) tools. By Tim LeCrone • Director of […]
