The Drive for Driverless Vehicles

Autonomous vehicles are a hot topic, most noticeably in the automotive world. But automated driving/operation is making significant headway in the off-highway realm as well, especially in mining applications. John Williamson of Komatsu America Corp. and Serge Lambermont of Delphi Electronics & Safety provide some insights on the topic. Read more at http://articles.sae.org/13300.

Chrysler's new Hellcat V8 gets 707-hp SAE rating

The actual J1349 rating is more than 100 hp more than Chrysler engineers teased in late May. The automaker's first production supercharged V8 uses a Lysholm-type twin-screw supercharger supplied by IHI. The engine's high-output spec required extensive upgrading of engine reciprocating components to handle the extra loads. Read more at http://articles.sae.org/13227.

Autonomous Black Hawk Helicopter

Sikorsky Aircraft Corporation
Stratford, CT

Sikorsky Aircraft, a subsidiary of United Technologies Corp., is developing its first product to feature Matrix™ Technology by converting a retired UH-60A Black Hawk helicopter into an optionally piloted variant capable of a wide spectrum of missions. With the autonomous Black Hawk, Sikorsky plans to build on the success of its Matrix Technology and Manned/Unmanned Resupply Aerial Lifter (MURAL) autonomy programs to deliver a new level of mission flexibility to combat and logistic planners. The product will integrate autonomy and advanced fleet management technology with refurbishment experience to provide a cost-effective, dependable and sustainable system.

Tata Technologies Researchers Use CFD to Predict Cavitation in Liquid Ring Pumps

Liquid ring pumps are used in aircraft fuel systems in conjunction with main impeller pumps. These pumps are used for priming the pump system as well as to remove fuel vapor and air from the fuel. Prediction of cavitation in liquid ring pumps is important as cavitation degrades the performance of these pumps and leads to their failure. As test-based assessment of cavitation risk in liquid ring pumps is expensive and time consuming, recent approaches have been to assess and predict the risk of cavitation using CFD methods with the goal to quicken the design process and optimize the performance of these pumps.
