One of the biggest issues in bringing forward new designs is the length of time that it takes to agree to a new specification, research and evaluate the alternative features and configurations, and then embark on a development program that will take the design to flight testing and ultimately operational service.
The fusing of emerging technologies from the aerospace materials sector and biological sciences are now, for the first time, heading toward the prospect of growing parts, systems, and, ultimately, perhaps whole aircraft.
Researchers from the U.S. Naval Research Laboratory's Optical Sciences Division and Material Science Division have detected acoustic emissions from cracks in riveted lap joints using a distributed feedback fiber laser-acoustic emission sensor.
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.
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.”
