Turbine blades in TiAl are about half the weight of comparable nickel-alloy components but boast the same reliability and durability. The high aluminum content also makes the material resistant to oxidation and corrosion.
The company expects to better support the use of additive manufacturing, or 3D printing, by releasing new OptiStruct solver capabilities for topology optimization. The company claims this new technology is the first tool developed specifically for designers of lattice structures.
In the area of electronics enclosures, traditional metal structures conduct and spread heat over large surfaces, but composites act as insulation. Heat generated by components causes internal temperatures to rise and has detrimental impact on the performance and reliability of the electronics.
The inventors of semiconductor chips or electronic parts most likely never imagined that over 50 years later, the aviation, space, and defense industries would be faced with the availability or proliferation of counterfeit electronic parts in their supply chains.
Delcam’s 2015 version of its PowerINSPECT inspection system includes automatic collision avoidance, faster import of large CAD files, quicker preparation of longer inspection reports, and improved display of results from point-cloud data, plus many other customer-requested enhancements.
At the McKinley Climatic Laboratory at Eglin AFB, an F-35 will ultimately be tested in all the meteorological conditions representative of those locations from which it will operate, ranging from the heat of northern Australia to the bitter cold of the Arctic Circle.
EOS and MTU Aero Engines are cooperating to apply new quality-assurance technology to direct metal laser sintering. The strategic partnership is expected to help advance EOS’ existing control and monitoring processes and further promote product quality in AM series production.
Bathymetric lidars—devices that employ powerful lasers to scan beneath the water's surface—are used today primarily to map coastal waters. At nearly 600 lb, the systems are large and heavy, and require piloted aircraft to carry them.
A new electrode design for lithium-ion batteries has been shown by Purdue researchers to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.
