Military Researchers Design Real-life 'Transformer' Plane



UK aerospace and defense contractor BAE Systems have taken the wraps off several concepts it envisions as possible tools for the military in the decades to come — and if these designs are any guide, future battlefields are going to look like the set of a science fiction movie.

The most interesting of the concepts is called the Transformer, a stealth aircraft that's actually composed of three airplanes — a large, diamond-shaped model, and two smaller flanking planes.

The Transformer is theoretically capable of longer flights that conserve fuel by reducing overall aerodynamic drag.

Right now, the most common aerial refueling techniques are the probe-and-drogue and the boom method, both of which require the delicate mid-air synchronization of separate aircraft. The Transformer would conceivably make the prospect of longer missions easier by requiring fewer mid-air fueling runs.

Alongside the Transformer, the firm also unveiled several other concept vehicles, including a self-healing aircraft called the Survivor (see video above). This plane repairs its exterior in mid-flight using a lightweight adhesive fluid within a pattern of carbon nanotubes.

BAE's concept videos also include an aircraft capable of shooting a concentrated energy beam to disable missiles as well as an aircraft (see video below) with the ability to fabricate and deploy UAVs (unmanned aerial vehicles) using on-board 3D printers.

But while BAE's advanced research group is known for coming up with fascinating innovations, the company is careful to mention that the concepts are mere predictions of what might be possible by 2040.

"[W]e don't know exactly what sorts of aircraft technologies will be used in 2040 with any certainty," said Nick Colosimo, an engineering manager from BAE's R&D team, in a statement. "But it's great to be able to show the public some concepts that might be possible through projecting where today’s technology could get to."

A 3D Printer Could Be Your Future Tattoo Artist

Ink junkies, take note— a machine could create your future tattoos.

Three French design students modified a MakerBot 3D printer to administer tattoos. One lucky volunteer is now the proud bearer of the world's first 3D-printed tattoo — a perfect circle on his forearm.

Pierre Emm, Piotr Widelka and Johan Da Silveira modified the printer as part of a challenge from France's Cultural Ministry and hosted through design school ENSCI Les Ateliers. For the challenge, the students had eight hours to create a project that remixes images, videos and sounds found in the public domain.

Though the original project used only a pen to create a temporary tattoo, the students worked in their spare time to create a printer that would create permanent tattoos.

The trio tested their machine using artificial skin before finding a volunteer and using a Scooter inner tube to the hold the skin taut.

The Mark One Is World's First Carbon Fiber 3D Printer


A new 3D printer can print carbon fiber and other composite materials.

Created by Boston-based startup MarkForged, it's called the Mark One.

Company founder Gregory Mark showed off the printer at the SolidWorks World design conference in San Diego, Calif. this week.

"We took the idea of 3D printing, that process of laying things down strand by strand, and we used it as a manufacturing process to make composite parts," Mark said in an interview with Popular Mechanics. "We say it's like regular 3D printers do the form. We do form and function."

In addition to carbon fiber, the Mark One can print other composite materials, including nylon, fiberglass and PLA (a thermoplastic made from renewable materials).

The advantage of 3D printing with composite materials, as opposed to the plastics that 3D printers typically use, is their strength; they are much stronger than plastics, and therefore have a wider range of potential applications.

The 3D printer will cost $5,000, and will be available for pre-order on MarkForged's website beginning in February. Mark said the company is keeping the price of the printer low to ensure that it's as accessible to as many people as possible.

"It's a material that everybody knows, but probably most people haven't used," he said. "We wanted to make it really easy for people to start printing with it, so they can explore prosthetics, custom bones, tools and fixtures."
