PACE FOUR T HE MICHIGAN IILY FRIDAY, YULY 10, I9d CELESTIAL NAVIGATION: Carver Heads Group on Fix-Crawling' ,t, * * By MURRY FRYMER "Fix-crawling" is the name giv- en to a new method of celestial air navigation developed by the engineering research department under the supervision of Prof. Harry C. Carver, of the mathe- matics department. Prof. Carver spent two weeks in December, 1951 testing the new navigation procedure device against severest weather condi- tions at Eielson Air Force base, 26 miles from Fairbanks, Alaska. "CELESTIAL AIR navigation is not new," Prof. Carver said. "In the last war we could find our position in 20 minutes by this means. At the rate of speed that planes now travel, 20 minutes is too long. In 20 minutes position will have changed by several hun- dreds of miles in our newer, faster planes," he maintained. - "The University was given the problem of discovering a quicker method of finding posi- tion. We believe we have found a solution." The importance of "fix-crawl- ing" in the region of the pole is further increased . because mag- netio disturbances in the -"' ion render a compass almcst useless, according to Prof. Carver. Although radio waves are the best way of determining position in peace time, belligerant nations in time of war would of necessity have to discontinue this method, since it would aid enemy planes as well as allied in detecting air- craft positions, he noted. PROF. HARRY C. CARVER ". .. easier working at the Pole" * * * ^* * * TO TEST "fix-crawling" the Alaskan Air Command asked Prof. Carver to try the device near the pole. "I think it's easier to work up there," Prof. Carver said. "I have flown 30,000 miles testing it, and it seems to work more easily up there than down here," he said. Prof. Carver stressed the import- ance of air bases in the polar re- gions. * * * HE EXPLAINED, "With bases at the north pole, none of these points are more than 3,000 miles from one another. There are in- numerable difficulties to overcome in establishing a military airbase under - arctic conditions," Prof. Carver said. "Fuel lines freeze in the planes," he claimed. "Oil lines break. There are problems of starting the motor. No ordinary plane motor would start under polar temperatures," he noted. According to Prof. Carver, one of the most unusual hazards would, be "ice fog." The "ice fog" is a polar cpndition in. which particlesi of dew in the air freeze, thereby forming an impenetrable density.j Lights are merely reflected back in the pilot's face, blinding him completely, Carver remarked. Soviet Power FightErupts (Continued from Page 1) maintained that it was "now evi- dent that Malenkov has the lead- ership of the party and the gov- ernment." * * * "THE MAIN question, therefore, is this: Is there a fundamental split in the party?" Pointing out that at present there seem to be "many issues of not so fundamental a nature as those that had arisen between Stalin and Trotsky," Prof. Neal indicated that "the split now is propably not so deep as it was in the 1930's. "The necessity for making deci- sions in new situations such as the recent levels in the satellites has brought conflicting ideas into the open. In such cases it is a mis- take to be in the minority." THE REMOVAL of Beria, Prof. Neal said, could result "either in a move toward more police oppres- sion-since the NKVD head was accused of having permitted for- :ign capialist plots against the USSR to succeed-or it could re- sult in a lessening of police op- pression. Agreeing to the basic reasons for the occurance, Prof. Henry L. Bretton also of the political sci- ence department said, it all points to the fact that it is impossible to expect a modern dictatorship to exist under collective leadership. "The most far-reaching conse- quences of the episode lie in the pasing of an era, Whether this will be for better or for worse no one can say, but with the removal of Beria the position of the pow- erful police apparatus must be changed. "Until now the secret police has been considered a very privileged group. With these developments, their power has been seriously threatened," he concluded. SRA To Tour Detroit Area An all day tour of interesting spots in Detroit, including the Art Institute, the International Insti- tute and the Rackham Memorial Bldg. has been planned for to- morrow by the Student Religious Association.
