Another and more important reason is the smaller, simpler engine. The turbojet has no propeller-a very vulnerable item. It has no delicate ignition system which a few flying chunks of steel can knock out of commission. It has fewer oil lines; it can get along, in fact, with very little lubrication. It needs no cooling system, except the air passing through it. The engine of the propeller-driven F51 has a tender pressurized cooling system with radiators and more than 20 feet of lines, and if any of these is punctured, the engine "freezes" quickly from overheating...
...principle, the afterburner is as simple as ABC. The tailpipe of an ordinary turbojet engine is lengthened and inside its throat is placed a grid of hollow, perforated cross-pieces. When maximum power is needed, fuel is squirted into the stream of hot gas racing out of the tailpipe. There is plenty of heat to ignite it and plenty of oxygen to keep it alight. So a vast yellow flame bursts out of the pipe, and the plane gets a mighty shove forward...
...drawing board." It is now producing the F-86D and F-86E, and in Engineer Kindelberger's view, they are obsolete too. When the Navy wanted a long-range bomber big enough to carry the Abomb, it turned to Kindelberger. The result was the AJ-1, with one turbojet and two reciprocating engines...
...single-seat jet fighter mounting four 20-millimeter cannon was undergoing new tests in Argentina last week, after whistling through a first trial flight clocked at a speed of 646 miles per hour. The swept-wing I.Ae. 33 Púlqui II, powered by a Rolls-Royce turbojet engine, is the second jet plane to be designed and built in Argentina. The designer: Professor Kurt Tank, former technical director of Germany's Focke-Wulf concern and designer of the formidable...
...motor, train and plane (including a special once-a-day turbojet transport which made it from London in 90 minutes), the first wave of a record crowd of 150,000 poured into Edinburgh. American collegians in crew cuts and seersuckers, arty Frenchmen wearing beards and corduroys, sturdy Scandinavians in hiking boots and shorts, grey-haired elders with guidebooks in hand thronged broad, flag-lined Princes and George Streets, puffed up Castle Hill, or jammed into pubs where Scotch was plentiful at 63? a double shot...
