...entry body would be a high-pressure air layer reaching up to 15,000° F.-about 1½ times as hot as the sun's surface. But beyond that, the physical properties of air at such speeds and temperatures were almost entirely unknown, and no existing wind tunnel was fast enough to furnish the necessary data. Kantrowitz' shock tube supplied crucial answers...
...sink cone. The snub nose, said Allen, would help pile up in front of the cone a high-pressure layer of air that would itself act as a potent insulator. That way, most of the immense heat would be swept off the edge of the cone into a long tunnel...
Another side of this sensationalism is "Westport comedy," as exemplified in The Marriage-Go-Round, The Tunnel of Love...
Over the California mountains, Lock heed test pilots had purposely flown test Electras into turbulent air at high speeds. Apparently because the planes' struts had not been weakened, nothing happened. But when company engineers, in wind-tunnel tests, purposely weakened nacelle struts to about the same condition as those on the crashed Electras, the fatal chain reaction began. The company had its answer. During all of this testing time, the Federal Aviation Agency had allowed airlines to fly Electras so long as their speed was held to a conservative 329 m.p.h. at 15,000 feet, thus removing...
...Canal & Tunnels. Last week, after a month-long site study (using some of Rommel's leftover contour maps and aerial photographs), nine West German scientists and engineers settled down to write detailed reports on a daring project to convert the Qattara into a mammoth new power project. First suggested by the British more than 30 years ago, the idea is to dig a ditch from the Mediterranean to within nine miles of the Depression. Thence a tunnel would be bored under the rocky escarpment that rises along the Depression's northern rim. Emerging from the tunnel, the water...
