...interest to let an important defense contractor become financially dependent on a foreign government. The Pentagon is urging Grumman to seek financing from U.S. banks instead. There also is a serious political question of how much the U.S. wants to assist the Shah in expanding Iran's sphere of military influence. Though it can operate from land bases, the F-14 is designed to be flown primarily off aircraft carriers, and Iran does not now have any-but high Pentagon officials confirm privately that the Shah is in the market for two carriers. If he can buy them, they...
...Kissinger, the Moscow summit was also important in personal terms. He surely sensed how the President, weakened by Watergate, was hampered in his bargaining with Brezhnev. Clearly, the freedom of the Nixon Administration in foreign affairs, as in every other sphere, was being cramped by Watergate. This fact may be one reason for the recent subtle change in the relationship between the Secretary and the President. Though the two men still agree on the basics of policy, Kissinger now seems more distant from the President than he did one or two months...
...avoid any attempt to steer the committee in only one direction. Aside from Strauch, most committee members point to Dean Whitlock as the most influential among their number. Whitlock, who has 26 years of administrative experience at Harvard, knows so much about how things operate in the undergraduate sphere, that members often defer to his experience...
Unlike dirigibles and other lighter-than-air ships, the Aerocrane gets only 40% of its lifting capacity from its helium-filled sphere. The rest comes from the rotation of its wings, which can be pitched as they whirl around to control ascent and descent. This gives the chopper-balloon a distinct advantage over traditional lighter-than-air ships, which must drop ballast or spill their gas when taking on or unloading any cargo. Yet because of the buoyancy provided by its supply of helium, the Aerocrane should be able to loft heavy cargo much more efficiently than a conventional helicopter...
Last week's test involved a working model consisting of a 15-ft.-diameter sphere with 9-ft.-long wings powered by ¼h.p. electric motors at their tips. Spurred by a $65,000 Navy contract, the firm is now studying the prospect of building full-size Aerocranes with spheres as large as 180 ft. across and wings of 126 ft. Powered by four 4,000-h.p. turboprop wing engines, the giant ship should be able to lift weights up to 90 tons-more than twice as much as any existing helicopter. Spinning slowly (8.6 r.p.m.), it will cruise...
