01.01.1970 //In Lockheed Martin they learned "to print" the robot- spies
At air show in the British city of Farnborough company Lockheed Martin demonstrated the uncommon unmanned flying vehicle Polecat. They are made according to the principle of the flying wing with a spread of 28 it is meter. But the chief characteristic of apparatus in the fact that the majority of its details are prepared with the method of rapid proto-typing, or, in other words, they are unsealed on the three-dimensional printer.

Unmanned vehicle Polecat.
Such printers sufficiently widely adapt in the engineering practice for the rapid production of the models of different details. Three-dimensional printers form models from the polymeric or shot, which is sinterred or layer after the layer with the aid of the laser beams is fused. This method costs less than the production of prototypes with the aid of the machine tools or by hand.
Certainly, the materials, utilized with rapid proto-typing do not befit for preparing the conduits, it is bridge or airliners, however, this method proved to be completely suitable for preparing the pilotless aircraft. In the case of Polecat on the three-dimensional printer was unsealed the large part of the details. Moreover, due to the use of polymeric composites with the admixture of the metals, which absorb radio emission, apparatus came out unobtrusive for the radars.
Use relative to inexpensive materials and sufficient extended technology of three-dimensional press made it possible to make Polecat by a relatively cheap apparatus. For the pilotless technology this is important factor. Furthermore, Polecat serves for the tests of the new system of preset control, which must allow apparatus to accomplish tasks without the aid of the operator
