Oilman Smith estimated that he could clean out the lines in two weeks, have oil pouring out the Eastern outlets in another two weeks. Their emergency use for gas was out of the question. Reasons: compressor pumps would have to be installed all along some 1,500 miles of pipe, and feeder lines built-a year's job. But, thanks to WAA's latest bungle, there seemed small chance that the pipelines would be used for months, for anything...
...great advantage of the jet engine is its simplicity. In contrast to the conventional reciprocating engine, the Bell P-59 motor has only four basic parts: 1) compressor, 2) combustion chamber, 3) turbine, 4) the cone-shaped jet through which the expanding gases that drive the plane are expelled. Because its operation, like a gun's recoil, is based on Newton's third law of motion (every action has an equal and opposite reaction), engineers prefer to call it the "reaction engine...
Engine Design. Since it has only one moving gear (the compressor and turbine, mounted on the same shaft), the jet en gine needs little oil. The plane needs no warmup, is ready to fly 30 seconds after the motor starts. The pilot, relieved of worries about oil pressure, fuel mixture, propeller pitch, etc., has only three controls to operate: the stick, the throttle and rudder pedals. Test pilots have found the P-59 more maneuverable in the air than a conventional plane. Taxiing on the ground is tricky. Because there is no propeller to blow wind against the tail...
According to a sectional diagram in the London Daily Express, a radio control unit is mounted immediately behind the warhead. Then come hydrocarbon and liquid oxygen fuel chambers, a centrifugal compressor, a combustion chamber, and a set of tail fins 10 ft. long...
Easier Way. But to engineers the chief point of interest was the bomb's simple power system. In the usual jet-propulsion machine, air is taken in at the front, compressed by a turbine-driven mechanical compressor (e.g., a fan), then mixed with fuel in a combustion chamber and expelled at the rear, the impact of the expanding air and gas, like a gun's recoil, giving the machine its push. But a compressor would have added greatly to the bomb's weight and complexity. To eliminate it, the Nazis...
