Heat-pipe embedded CFRP enclosures for electronics thermal management

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.

Altair optimizes 3D-printed structures for complex, lightweight designs

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.

Growing pains (and gains) of P&W's Pure Power engine

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.

RCCI engine begins in-vehicle demonstration testing

Higher fuel efficiency and reduced exhaust emissions are two potential benefits associated with Reactivity Controlled Compression Ignition (RCCI), a dual-fuel combustion strategy being spearheaded by a team at the University of Wisconsin-Madison.

Airframe drilling and countersinking book

Offers a stepped approach for evaluating possible areas for applying automation and a detailed description of the process for choosing, acquiring, and transitioning the right machinery for success.

Unmanned aircraft must rise above barriers for commercial applications

For years, the most sophisticated UASs have employed “autonomous” algorithms that allow them to operate for hours without human intervention or control. This autonomy can be perceived as true intelligence but also as dangerous—raising concerns about accidents and moral and legal accountability.
