Much of the technology found in today's consumer automobiles was originally designed to give race cars a competitive edge. With that in mind, Australian entrepreneur Matt Pearson figured that if there's one way of accelerating the development of flying cars, it's to race the things. To that end, his company Alauda is now building what is essentially a human-capable racing drone.

Abstract Two limitations of additive manufacturing methods that arise from layer-based fabrication are slow speed and geometric constraints (which include poor surface quality). Both limitations are overcome in the work reported here, introducing a new volumetric additive fabrication paradigm that produces photopolymer structures with complex nonperiodic three-dimensional geometries on a time scale of seconds. We implement this approach using holographic patterning of light fields, demonstrate the fabrication of a variety of structures, and study the properties of the light patterns and photosensitive resins required for this fabrication approach. The results indicate that low-absorbing resins containing ~0.1% photoinitiator, illuminated at modest powers (~10 to 100 mW), may be successfully used to build full structures in ~1 to 10 s.http://advances.sciencemag.org/content/3/12/eaao5496
“It’s a demonstration of what the next generation of additive manufacturing may be,” said LLNL engineer Chris Spadaccini, who heads Livermore Lab’s 3D printing effort. “Most 3D printing and additive manufacturing technologies consist of either a one-dimensional or two-dimensional unit operation. This moves fabrication to a fully 3D operation, which has not been done before. The potential impact on throughput could be enormous and if you can do it well, you can still have a lot of complexity.”Volumetric 3D printing creates parts by overlapping three laser beams that define an object’s geometry from three different directions, creating a hologram-like 3D image suspended in the vat of resin. The laser light, which is at a higher intensity where the beams intersect, is kept on for about 10 seconds, enough time to cure the object.

Stirling Dynamics has been awarded a new contract from WheelTug to deliver a new nose wheel design for the Boeing 737NG family of aircraft, which will be fitted with the WheelTug system. The WheelTug® system is a unique and disruptive technology that consists of a nose wheel mounted motor and drive, powered by the aircraft's Auxiliary Power Unit (APU), and aims to save time, engine life and fuel use resulting in reduced emissions and significant cost savings for aircraft operators.
Stirling was chosen to carry out the work due to our niche capabilities in landing gear design and analysis. Under this contract, we will be helping WheelTug design and achieve certification for this brand-new landing gear nose wheel. Our engineering team will draw on the company's core capabilities in reverse engineering, wheel analysis, landing gear analysis, safety analysis and structural stress analysis.
On this new contract, Stirling's Aerospace Business Manager, Bandula Pathinayake stated: "We are proud to work on this innovative technology with the WheelTug team, this new contract is another step forward in seeing this innovative technology reaching the marketplace."
Early last year, we first heard about Fraunhofer's DEDAVE (Deep Diving AUV for Exploration) unmanned submersible. Then this July, we got word of an initiative aimed at locating sunken flight models of a famous Canadian jet fighter, the Avro Arrow. Now, the two have come together – Fraunhofer is reporting that one of its DEDAVEs has located a couple of of the models.
