Eight Gigahertz. The M.I.T. team also had to design a new radar transmitter that would operate at eight gigahertz (pronounced with hard gs), which is 8 billion cycles per second. Radar beams of lower frequency would be significantly slowed down by electrons in the solar corona, making it difficult to separate out the delay actually caused by the sun's gravity. Corrections for Mercury's surface irregularity had to be calculated; round-trip time to a Mercurial valley would be longer than to a mountaintop. It was also essential for the researchers to screen out any extraneous radio...
...Ellen Klein '68, co-chairman of SDS, and Peter J. Bilazarian '69, member of the executive committee, distributed their two-page mimeographed "white paper" after yesterday's 11 a.m. lecture. Bilazarian said last night that the critique, which also bears the names of Lawrence M. Robinson GS-1 and Steven W. Raudenbush '68--both SDS members--was not officially approved...
...that problem. They are developing a "very promising" jellied fuel that burns slowly and does not leak from ruptured tanks. The Pentagon and the FAA are experimenting with "tough wall" tanks made of nylon and polyurethane; when a tough-wall helicopter was slammed against a jagged rock at 100 Gs, the crash left only a one-eighth-inch crack. Airlines are also experimenting with a fire-resistant foam, which would automatically flood the fuselage after a crash and protect the passengers...
When the rocket is launched, its engine and the auxiliary fuel will be ignited at the same instant. The trapped combustion gases will produce a pressure of 500 lbs. per sq. in. that will drive the rocket upward with 3,600,000 lbs. of thrust and about 35 Gs of acceleration. It should reach the end of the tube in 1,205 sec. Air pressure will open the doors to let it pass, and it will pop out with the respectable speed of 1,000 m.p.h. Only 2,500 lbs. of its own fuel will have burned, and it will...
...tough as combat operations, and sometimes men get hurt or killed." In preparing for the Eglin show, one did. Captain Charles G. Lamb Jr., 31, of Indianapolis, died when his F-10s disintegrated at 2.000 ft. as he practiced a supersonic bomb pullout with a force of 4.25 Gs...
