After many years of flat-lining in the supply of new commercial jet engines—with improved models, but with designs dating back to the late 1990s, relying on a continuous path of evolutionary development—a new generation of super-efficient powerplants is entering service, introducing many technologies that will also be applied to future engines.
As part of a recently announced initiative, NASA is in the midst of researching a number of strategic projects that include quiet supersonic flight, electric distributed propulsion, and hybrid wing aircraft, with goals that include demonstrating advanced technologies to reduce fuel use, emissions and noise, and accelerate possible introduction to the marketplace.
E-Jets E2s are based on the proven platform of the current-generation E190, but with more advanced technologies applied such as new aerodynamically advanced high-aspect ratio wings and geared turbofan engines from Pratt & Whitney.
Zephyr 8 has a wingspan of 25 m and can carry 50% more batteries than the earlier version, yet is 30% lighter. This translates into a UAV that can carry a heavier payload and is designed to, typically, stay in the air continuously for over a month
Rolls-Royce will designate Purdue as a University Technology Partnership, which will initially encompass two research centers in the areas of advanced thermal management systems and advanced compressor systems.
The LM-100J will be the civil-certified version of the C-130J and an updated version of the L-100 (or L-382) cargo aircraft, and will be “the only commercial airlifter that offers all-terrain and all-weather service.”
