MIT and NASA engineers display an invisible aircraft shield



A new approach may offer greater flexibility in future aircraft design and manufacture. The new shield design was confirmed in the NASA wind tunnel and explained in the Materials and Structures magazine.

Instead of hopping in the hull and in that attack to move aircraft in traditional aircraft, such as elerons, the new system can either erase the whole or part of the shield, sharing, t hard and flexible parts of their structure. The details together make an open, light-elaborate finish that is coated with a thin layer of similar polymer.

This makes the wings that are much lighter, much more energy than the ordinary, made of metal or mixed materials, researchers say. The vast majority of thousands of games are similar to concentric triangles and produce a mechanized metamaterial which links the rigor of the polar like the rubber and the lightness of the armor and low air density. T .

One of the creators of this shield, Benjamin Jenett, a postgraduate student at the Massachusetts Institute of Technology (MIT), works at the Bit and Atom Center, explaining that all levels of the flight, go, excursion, will be canceled. moving, etc. There are different differences on the best shields, so it is inevitable that standard shields will not have the best effect on any of the steps taken, causing loss of efficiency. With the ability to swiftly change the shield, it may be possible to set the best boundaries for each flight level.

Whilst changing the shape with engines and ropes, the team went on to develop and develop a system that automatically responds to aerial users by changing form – process, tolerant of card redesign.

“We can increase efficiency by changing the shape to maximum effect when an attack angle changes. We can make the same change that you could do actively, but we do it effectively, ”said Nicholas Cramer, chief engineer at NASA's NASA Research Center.

All this was achieved by careful selection of different sites than different stances or flexibility, and the shield or part of the loop has been flexed accordingly.

MIT's graduate Kenneth Cheung, who now works at the NASA Ames Center, has become headquarters to colleagues in recent years when he built a wing of about one meter in total. similar to the normal shield of a remote control model. The size of the new turbine, which is about five meters long, is like a true flightplane shield and is easy to do.

Though a team of 39 students has chosen this option easily, these repetition procedures could be easily achieved by groups of simple, simple robots. T independent. The design and testing of a robotic assembly system under another theme is Yenette.

Individual parts of the previous wing were cut with a water ball, each given a few minutes. In the new system, the parts are formed from taking a polyethylene down to a much wider 3-D shape, and all the details – especially in a gap of size-dimensions. decorative features on both sides – come in at least 17 seconds, which results in a slightly larger result.

Concentration of the cells is as a result of only 5,6kg / m³. To compare, the polymer density is ~ 1500kg / m³. "The hardship is the same, but the density of our output is around a thousand times lower," said Yenette.

Because the shape of the wings or other structures is made of detailing, their shape is less important. “You can create a geometry. Most planes have the same form (especially wing pipes) because of its cost. It's not always the most effective way, ”said MIT student. However, by its very nature, the major investments in design, equipment and production make it easier to maintain up to date capabilities.

Research has shown that in most cases there would be much more effective fuse and wing structures in most cases, it would be easy to design, test, modify and test with this system, it says.

“The survey shows how big, light, tightly-shaped structures will be reduced and developed. The most promising options for the future are aircraft and space structures such as antennas, ”said Daniel Campbell, researcher at the Aurora Flight Sciences, from the Boeing engineering unit.

The new wing was designed to fit into a remote wind tunnel at NASA's Langley Research Center, where it was likely that Yenette ranked it better than expected.

The same system could be used for other structures such as shield-like wind turbines, where the ability to gather them locally would solve the problems of carrying smaller blades. to the ground. t Similar solutions are created to construct structures in space and may be bridges or other structures.
