Airplanes are slowly outgrowing their need for long runs on the ground before getting into the air. The reason is jet engines, which deliver so much thrust that they can lift themselves and an airframe vertically, without needing take-off help from the lift of a fast-moving wing...
...Corp.'s X-14, whose pictures were made public last week. Unlike Ryan Aeronautical Co.'s X-13 (TIME, May 20), which stands on its tail while taking off, the X-14 takes off in normal horizontal flying position. Its two jet engines blow their gas through thrust-diverters rather like Venetian blinds. The gas, deflected downward, pushes the airplane up. During the hovering period, jets of compressed air act as controls to keep it in the proper position. After the airplane is well off the ground, the thrust-diverter can be adjusted so that the engines push...
...week's end, in a telephone address to a regional conference of Republican leaders in Trenton, N.J., Ike called for legislation giving the President the power to veto individual items in appropriations bills as "one simple way to save a lot of money"-a thrust at congressional budget-cutters who favor economy on everything except pork-barrel projects for the voters back home...
Liquid v. Solid. Watching the figures soar, dozens of big companies are hurrying into the field to share the bonanza. General Electric, after a start in small rockets, is now producing the big (100,000-lb. thrust) first-stage rocket for the Vanguard earth satellite. Curtiss-Wright is producing small antitank rockets for the Army, is working on a throttle-equipped" rocket engine for planes and missiles. Bell Aircraft, Hercules Powder, Phillips Petroleum, General Motors and many others are developing new engines and materials to fuel them...
...cooled v. liquid-cooled engines, is over solid rocket propellants v. liquid rocket propellants. Most big rockets, including both Intercontinental and two of the three Intermediate-Range missiles, now use liquid fuels with an oxidizer such as nitric acid or hydrogen peroxide. Liquid systems have produced the highest thrust-weight ratio (80 Ibs. for each i Ib. of weight), but they require an enormously complex system of tanks, valves, pumps and generators. To feed and control its monster engines North American must have pumps capable of 8,000 gal. per minute (enough to empty...
