While the hatch problem was being solved, NASA and North American Aviation engineers went to work on combustible materials that had cluttered Apollo's spacecraft before the January fire. Aluminum plumbing which melted at 1080° F. has been replaced by stainless steel. Brazed joints that withstand temperatures approaching 1,600° F. have been substituted for soldered joints that melt at 360° F. Coolant pipelines, which service electronic components and can release flammable glycol when ruptured, have been "armor-plated" at joints with high-strength epoxy. Should the joints come open, the epoxy serves as a back...
...time to look for them." Titanium is used in jet aircraft, and although both engineers termed the idea of using TRIP-processed materials to prevent metal fatigue "pure speculation" at this point, it is not beyond the realm of possibility. Other conceivable uses of TRIP steel: storage tanks to withstand the super-coolness (as much as -450° F.) of liquid helium, hydrogen, nitrogen and oxygen; chemical-processing equipment; roller and ball bearings. TRIP, in the estimate of its discoverers, is capable of being produced commercially at prices competitive with other high-strength steels. It may some day be used...
Taut Crossbow. The Calder is not an unmitigated success, partly because it was necessary to blunt its knifelike edges with heavy reinforcements to enable it to withstand the brisk winds that blow off the St. Lawrence. It suffers, like most Expo sculpture, from comparison with the bizarre silhouettes of the pavilions. Nonetheless, most fairgoers like Calder's Man. Murmured one miniskirted coed, gazing up at it last week: "I like the strength and the way it springs up. It has power, like a human being. Flowers spring up, but not in the same...
...some real know-how." Prestressed concrete was used for the 16 radial buttresses, while the roof was prefabricated from huge slabs of concrete hauled into place by the largest tower crane in Europe after a model of the cathedral was tested in a wind tunnel to prove it would withstand the impact of three Boeing 707s...
...enough heat exposure to kill even the organisms within the solid metal structures of the spacecraft. Aware that sterilization of some early Ranger moonships damaged spacecraft systems and led to the failure of missions, scientists are spending time and money to design new Voyager systems that will withstand prolonged heating...
