Unlike the radical swept-wing design of modern U.S. jet jobs-fighters and bombers-the Canberra is basically a handsomely cleaned-up version of traditional designs, with a wing that looks fairly conventional to the man on the ground. Powered by two Rolls-Royce Avon turbojet engines, it is rated at a top speed above 600 m.p.h., can be fitted with wingtip tanks to extend its range. The Canberra was designed as a high-altitude radar bomber, can also perform all normal fighter maneuvers, and has shown possibilities as a low-level ground support plane. Said Pilot Callard: "A most...
...meet these Air Force requirements Boeing will offer its XB-52, believed to look much like its six-jet B-47 medium bomber, now in production. The XB-52 has wings swept back at a 35° angle, and eight turbojet engines...
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...
