Predicting cavitation in fuel pumps

Liquid ring pumps are used in aircraft fuel systems in conjunction with main impeller pumps and serve the function of removing fuel vapor and air from the fuel. Thus, their reliable functioning plays a critical role in the safe operation of aircraft during flight. Read more at http://articles.sae.org/12709.

Air And Missile Defense System To Get Smarter Software

When a missile is launched against an enemy target, it would be nice to have a lot of good information about that target. But when "decision makers push the fire button, they may have very little data, and sometimes not timely enough data," said Col. Rob Rasch Jr., project manager, Integrated Air and Missile Defense Project Office, or IAMD, at Redstone Arsenal, Ala. "Nowhere in the current Army architecture is there a way to share information from all of our various sensors and weapons to have better integrated coverage," he pointed out, referring to situational awareness for those operating Patriot and other missile defense systems like those used for short-range air defense.

Army Researchers Inspire Commercial Rifle Fire Control Systems

Researchers at the U.S. Army Research Laboratory go about their business every day working on projects to help better serve the military and its members who protect our country. Sometimes the research inspires commercial companies to do additional research and expand on certain aspects to develop products of their own. That is what happened with the Army Research Laboratory's (ARL's) research called "Inertial Reticle Technology," where researchers who were then in the Weapons and Materials Research Directorate developed a concept to apply advanced fire control technology to sniper weapons.

Canadian researchers employ recycled carbon-fiber mats to produce thermoset composites

Carbon-fiber-reinforced thermoset composites continue to be difficult to recycle, as they are a complex mixture of different materials such as thermosetting polymers, carbon fibers, and fillers. Researchers from the Universite Du Quebec at Montreal, Bell Helicopter Textron Canada, and the National Research Council Canada investigated using carded recycled carbon-fiber mats and epoxy resin to fabricate thermoset composite plates.

Heated air technology helps optimize CFRP assembly

Assembly of large and complex carbon-fiber-reinforced plastic (CFRP) components requires the use of liquid resin-based materials for applications such as shimming and aerodynamic sealing. These materials generally require curing times up to 12 h; heated air technology can reduce that time to 2 h. Read more at http://articles.sae.org/12510.
