Avionics go to war Advanced helmet sight systems are being designed to help the situational awareness of those pilots who actually still fly aircraft, while also being seamlessly integrated with the aircraft itself. Model military engine behavior While the concept of a variable cycle engine is not new, recent advances in engine architecture technology suggest that adding a second bypass stream to a traditional turbofan can provide significant benefits. Alternative seals for alternative fuels When considering seal compatibility an aircraft from traditional jet fuel to a synthetic fuel presents an interesting technical challenge that has both financial and practical considerations, especially for aircraft that are already in service.

Prime time for batteries Forecasts very on how many, and when, electrified vehicles will hit the streets, but auto and battery makers are ramping up efforts like there's no tomorrow. In energy storage, materials matter Batteries being electrochemical devices, innovation and advances in chemistry and materials are key to what everyone agrees is the need for improved performance and life. Comparing thermal characteristics of Li-ion celss Most Li-ion battery suppliers require that the cell temperature be as uniform as possible to achieve optimal battery performance and avoid battery system failure. But some materials in Li-ion cells have low thermal stability. The world plugs into EVs As matters begin to settle in terms of connector types, charge-station makers are ramping up to meet the needs of a growing population of plug-in vehicles.
