Want to listen to the stars? Do it with steel wire! (Oct, 1961)
Want to listen to the stars? Do it with steel wire!
The University of Illinois will soon begin operating a mammoth radio telescope to map and catalog radiation from galaxies that are invisible to optical telescopes. The findings will throw further light on the evolution of stars and perhaps help solve other mysteries of the universe.
The telescope they will use is a triumph of human ingenuity and proof that engineers, builders and designers are limited only by their imagination. Here, the imaginative use of steel wire saved thousands of dollars and simplified what could have been a prohibitive construction job… building a reflector big enough for the telescope. Instead of building the reflector up, they scooped it out of the earth – a trench 600 feet long, 400 feet wide, and 65 feet deep. Then they lined the trench with 5-3/4 acres of wire fabric joined into one electrical entity. This giant screen reflects radiation and focuses it onto 300 antennas arranged on a horizontal 425-foot-long truss that towers 165 feet above the apex of the reflector.
In the towers too, special prestressed guy wires solved the problem of safe, strong, precision support that prevents movement of the antennas and “blurring” of the reflection.
Before this project was conceived, who would have dreamed of a telescope made of wire? Only an imaginative problem solver. Perhaps one of your problems can be solved with imagination and steel wire. American Steel and Wire engineers worked closely with the project engineers to solve the problem with wire . . . the strongest form of steel, and one of the most adaptable. Imagine how you can use it.
