Nekako po navika vojnite temi gi stavame tuka na avijacija, a i nemame poseben podforum za takvi temi, pa se nadevam moderatorite kje ja dopushtat.
Eve da ukazham na eden interesen novitet koj mislam deka e interesen so ogled na problemot na nagazni mini na mnogu mesta vo svetot. Imeno se raboti za novoto "neprobojno trkalo":

The military wants an alternative to the current Humvee "run flat" tires, which despite the name, still need a minimal amount of air pressure to roll and can leave troops stranded after being shot or blown out.
"You see reports all the time of troops who were injured by an IED or their convoys got stranded because their tires were shot out," said Resilient's General Manager Mike Veih. "There's all sorts of armor on the vehicle, but if you're running in the theater and get your tire shot out, what have you got? You've got a bunch of armor in the middle of a field."
In developing the design, the Wisconsin team studied other airless tires, like the Michelin "Tweel," but in the end settled on lessons learned from nature.
The patent-pending design mimics the precise, six-sided cell pattern found in a honeycomb and best duplicates the "ride feel" of pneumatic tires, according to the developers.
"The goal was to reduce the variation in the stiffness of the tire, to make it transmit loads uniformly and become more homogenous," said mechanical engineering professor Tim Osswald. "And the best design, as nature gives it to us, is really the honeycomb."
This particular geometry also does a great job of reducing noise and heat levels while rolling-two common problems with past models.
Costs per tire are expected to be the same or less than current units. Delivery is anticipated for 2011.
