U of Illinois team models capabilities of hybrid-electric propulsion systems for general aviation aircraft

Green Car Congress

Researchers at the University of Illinois at Urbana-Champaign have utilized a series of simulations to model the performance of twin-engine hybrid-electric general-aviation propulsion systems. Jet fuel and aviation gasoline are easy to store on an airplane. Their paper appears in the Journal of Aircraft. Dean, Gabrielle E.

U of I team uses frontal polymerization for rapid energy-efficient manufacturing of polymers; saving 10 orders of magnitude of energy

Green Car Congress

Researchers at the University of Illinois have developed a new polymer-curing process that could reduce the cost, time and energy needed, compared with the current manufacturing process. There is plenty of energy stored in the resin’s chemical bonds to fuel the process. Robertson, Mostafa Yourdkhani, Polette J. Lloyd, Leon M.

The State of the Transistor in 3 Charts

Cars That Think

But size isn’t the only feature engineers have been improving. Behind that barely conceivable number is the continued reduction in the price of a transistor, as engineers have learned to integrate more and more of them into the same area of silicon. Seeking raw speed, engineers at Northrop Grumman made a HEMT that passed 1 terahertz.
