...more), the first time that United has bought anything but U.S. planes. Another Caravelle has been sold in the U.S. to Jet-Engine Builder General Electric Co., which will use the plane as a flying showroom for its new CJ-805-23 aft-fan engine, which delivers more thrust for lower fuel consumption than standard jet engines. G.E. sees a bright future for the medium-range French plane, and wants its engine to replace the Rolls-Royce power plant now in the plane...
More important than the rumbling of the defense debate last week was the roar of a 110-ton Titan intercontinental ballistic missile lifting cleanly into space with 300,000 pounds of thrust. After nine months of frustrating failure at its Cape Canaveral pads (which crews had dubbed "the inferiority complex"), Titan No. B7A got off to its first two-stage flight. Two minutes and 50 miles downrange, its second stage kicked in with 80.000 pounds of thrust, a roar heard round the world because Titan's 41-foot, 24-ton second stage is the largest vehicle known to have...
...Discoverer satellite failed to orbit (because malfunctioning ground gear cut off its in-flight power 15 seconds too soon). Discoverer's record in nine tries: six orbits, three misses (all due to ground equipment lapses). ¶The Saturn cluster engine, with an awesome 1,500,000 pounds of thrust, was earmarked for another $90 million in 1961 budget cash, lifting it to a fat $230 million for the year. The Saturn will shake through its first ground tests at Huntsville, Ala. in April, when Rocketeer Wernher von Braun will switch on two of its engines; later tests will step...
...conventional rocket engine, fuel is burned in a roughly spherical combustion chamber, and turns into hot, high-pressure gas. To keep the gas from expanding wastefully in all directions as it leaves the nozzle, it is channeled into a tail cone where its pressure is efficiently converted into thrust as it expands (see diagram). The cone should be long enough to reduce the pressure of the gas to that of the surrounding atmosphere. Thus rockets intended to work at very high altitudes must have extra-long tail cones...
...into many small segments, each with its own fuel supply. By adding segments, the engine can be built in very large sizes without running into the difficulties that plague the designers of single combustion chambers. Single-chamber rockets are steered by mounting their engines on gimbals so that their thrust can be switched from side to side. With plug nozzle engines, the same control can be achieved by varying the fuel supply of one or more of the combustion chambers...
