Tooling decisions play major role in cost, turnaround time

2018-07-24
“Laddering up” of the range of tooling options requires assessing at each plateau whether greater upfront investment in tooling will pay off with a relatively quick return on investment. Since tooling plays such a key role in this equation, it also means working closely with OEMs willing to evaluate the best available tooling options at any time as production requirements increase.

Additive manufacturing adoption up, growing rapidly in aerospace

2018-06-14
The 3D printing materials market will experience high double-digit growth in the aerospace industry through 2024, as manufacturers of aircraft and spacecraft vehicles and components increasingly adopt and reap the benefits of additive manufacturing, market analysts at Frost & Sullivan in Mountain View, California, predict.

FAA, SAE International focus on engine fire protection system standards for aerospace

2018-06-18
Aerospace systems, subsystems, and components must continue to operate as intended when exposed to fire, rather than going up in flames and ceasing to work altogether. Fire and flammability testing is an all-important prerequisite to airworthiness, and the focus of a new technical standards committee that SAE International in Warrendale, Pennsylvania, is forming in response to a request from Federal Aviation Administration (FAA) officials in Washington.

Fokker uses ZwickRoell creep testing machines to test for hydrogen embrittlement on landing gear components

2018-10-17
Aerospace manufacturers walk a metaphorical balance beam to continually develop and produce stronger, more efficient materials and components, while addressing all potential failure modes. This is true for safety-critical aircraft components like landing gear systems. Fokker Landing Gear B.V./GKN Aerospace recently equipped its mechanical laboratory with three creep testing machines to verify its manufacturing process control of zinc-plated bolts for aircraft landing gear systems.

GM's CTO driving new paths to technology leadership 'We're making actual production commitments regarding our advanced-technology strategy, rather than just talking about it,' says GM's CTO Jon Lauckner. 'We're absolutely going to be among the leaders, if not the leader, in these areas.' Aluminum prepares for its next big leap Ford's F-Series blockbuster was just the beginning. New micromills now in pilot phase aim to bring vastly stronger and more formable light-alloy materials at higher capacity, says Alcoa's Mike Murphy. Slick solutions for friction reduction From new lubricants to 'smart' oil pumps and clever bearing technologies, engine designers are attacking every potential source of spin losses and internal friction in the quest for more mechanical work out of less fuel.

Driving EVs toward lower cost The race is on to reduce battery and electric-drive systems costs while improving efficiency. Seeking ways to make better computer crashes New models and simulations help improve safety as software and hardware provide more realism to iterate designs more quickly. Evaluating aluminum bonds Adhesively joined aluminum alloy sheets present challenges that steel-adhesive joints do not. Ford researchers present a modified technique to inspect Al-adhesive joints in lab and production environments. Leading the attack on engine pumping losses Cylinder deactivation delivers real-world fuel economy gains, helping vehicles to meet and exceed their sticker numbers.

Comparative Performance of 12 Crankcase Oil Mist Separators

2018-10-31
Abstract Closed crankcase ventilation (CCV) systems are required in most automotive markets in order to meet emissions regulations. Such systems usually require a separator to recover oil and return it to the sump. Many end users fit improved separators in order to reduce intake/aftercooler contamination with soot/oil. This study measured clean and wet pressure drop and filter capture efficiency in 12 different crankcase oil mist separators which are commonly used for either original equipment (OE) or aftermarket fitment to passenger vehicles and four-wheel drives (≤200 kW). The filters tested spanned three different size/rating classes as well as included both branded and unbranded (imitation) models. In addition to filters, separators (often termed “catch cans”) and an OE cyclone separator were also examined. Testing was performed under controlled laboratory conditions using methods equivalent to previous work and current mist filter test standards.
