...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...
...within 20 feet of the jets would be burned to a crisp. But in the air, the fuel is burned so completely in the combustion chamber that the jets show no flame, even at night. The openings in front of the plane through which air is sucked into the motor posed a problem: they also sucked in birds. Engineers have partly solved the problem by screening the intakes...
...rough-and-tumble contest was largely similar to the 47 to 35 licking which the Crimson suffered at the Motor Torpedo Boat Base in Rhode Island last month. In handing the Varsity its twelfth defeat of the campaign, Melville showed an edge in height, experience, and stamina which proved too much for the Stahlmen...
