...sleek Tomahawk cruise missile. As big jack rabbits nibbled unconcernedly at the sagebrush in the blazing morning sun, a camouflage-painted, torpedo-shaped object whistled barely 100 ft. above the White Sands Missile Range at 500 m.p.h., headed dead on target. Brown listened to the whine of its turbofan for a few seconds, then put down his binoculars and turned to reporters near him, the first press group to witness the highly advanced missile. "I believe that it is important that the American public correctly perceive that the U.S. is not inferior to any country in military capability," said...
...testing, the YF-16 prototypes proved to be more agile at the Mach 2 speeds at which the planes were designed to fly. But General Dynamics also showed a shrewd appreciation of Pentagon pride and politics. To power the YF-16, the company chose the same Pratt & Whitney turbofan engines used in the Air Force's costly ($12 million) but cherished new McDonnell Douglas F-15 Eagle long-range fighter. The General Dynamics fighter thus meshes neatly with the concept now gaining popularity in the Pentagon of a "HiLo Mix" in weapons systems. In essence...
...cost than other SSTs. On takeoffs, with its wing at right angles to the fuselage, he says, the plane would require only one-fourth the power of the Russian TU-144 or the Concorde, both of which have fixed delta wings. Thus it could operate with conventional, relatively quiet turbofan jets, sharply reducing noise on landings and takeoffs. It would also prevent pollution of the stratosphere by burning less fuel and by flying at lower jet altitudes (40,000 ft. v. 65.000 ft. for the originally proposed U.S. SST). Finally, unlike other SSTs. it could fly economically at Mach...
Price also seemed to be the key reason behind the choice of engines for United's DC-10s. All the planes to be built by Lockheed will be powered by British Rolls-Royce turbines. United, however, opted for General Electric's CF6/36 turbofan at slightly over $2 million per plane, putting the U.S. enginemaker a bit below Rolls. It is a price that may well move American to choose G.E. engines...
Electric and Pratt & Whitney; the Rolls RB-211 turbofan was the engineers' choice because of efficiency and lower noise levels. But at $2,500,000 a plane, the British-made engines meant a $235 million drain on the U.S. balance of payments. Lockheed solved this with an arrangement in which Ah" Holdings will sell 50 of the early L-1011s abroad. This will bring in $625 million for a favorable U.S. balance of $390 million, and further sales in a market estimated at 1,000 planes by 1980 could raise the U.S. excess to well over $5 billion dollars...
