| 描述 | With a thrust of twenty-five metric tons, the V-2 motor was the world's first large, liquid-fuel rocket engine and powered the first ballistic missile, the German V-2 of World War II. The combustion chamber was the engine's heart and burned the propellants, water alcohol and liquid oxygen, at about 2,700 ºC (4,900 ºF). Water alcohol was injected through six pipes near the bottom of the chamber, moved up between the walls in order to cool the chamber, emerging through the sides of the eighteen injectors on top. Small pipes also injected alcohol into the chamber through rings of tiny holes in order to provide a insulating film of fuel along the walls. Liquid oxygen was injected directly into the top of the injector heads. A pyrotechnic igniter started combustion, after which burning was self-sustaining. Steven F. Udvar-Hazy Center. | ||
