US military researchers are testing a prototype of puncture- and deflation-free "airless" tires designed for non-stop passage of military SUVs through "hot zones" of hostilities. If implemented successfully, the new technology can be extended to civilian models, replacing traditional car tires.
The advantages of cellular tires are obvious, but scientists will spend a lot of effort looking for an appropriate material that can withstand the pressure of a multi-ton war machine.
Resilient Technologies' "Non-Pneumatic Tire" (NPT) will allow Army SUVs to continue driving even after up to 30% of the tire honeycomb has been destroyed. In April 2009, Resilient installed 94-centimeter NPT tires on an Army All-Terrain Vehicle of the Vozo, Wisconsin National Guard, which is currently being road tested.
Two years have already been spent on the development of tires, Infuture. RU reports. The company ran static load tests on one of the NPT prototypes. It withstood a maximum load of 1,746 kg, which meets the requirements of the military. Stressing the plastic provides strength, allowing airless tires to operate just like air-filled tires.
