Rising Ratio. The ideal VTOL may come into being through the continuous improvement of jet engines. Research Engineer Earl R. Hinz of Ryan Aeronautical Co. points out that when the static thrust of an airplane's engines exceeds the airplane's weight, a vertical take-off is possible-at least in theory. Apparently no operational jet plane has such thrust at present, but the ratio of thrust to weight-even with the low-power figures still published by the security-morbid U.S. Department of Defense-is climbing rapidly. For the F-86 Sabre jet the ratio is four...
Ready he was. His driving genius won back the lead for United and the U.S. with Pratt & Whitney's burly J57 engine (more than 10,000 lbs. of thrust); it currently powers Air Force and Navy planes from supersonic Century fighters to B-52 bombers, is one of the big reasons why Douglas' DC-8 and Boeing's 707 transports are sewing up the commercial jet market. Several months ago Fred Rentschler's health began to fail. Last week, at 68, he died at his Boca Raton, Fla. home. Almost until the end, United...
...hrushchev's big thrust for power began back in 1937 when Stalin picked him to pacify the Ukraine, then in ferment as a result of Stalin's brutal collectivization of the rich farm lands. What made Khrushchev the right man for the job was that he was a peasant and could be expected to handle the peasants in terms they understood...
...general shape of the TU-IO4 proves that it is a partial redesign of the twin-engined jet bomber that the West has dubbed the Badger. Like the Badger, its two engines are very large (estimated thrust: 20,000 Ibs. each). This is not necessarily a plus; Western designers, with that kind of horsepower available, like to split their power among four, six or eight engines to reduce frontal area per engine and spread thin potential troubles from engine failure...
Throttled Rocket. Most rocket motors are all-or-nothing performers. They give good performance at one thrust level only. The Bell X-1 (first airplane to pass the speed of sound) was pushed by a cluster of four small rockets, and it gained a measure of control because the pilot could shut some of them off. The Bell X-2 (already under secret test) has a two-rocket Curtiss-Wright power plant, can vary its thrust, by methods undisclosed, over a considerable range...
