世界上第一架轨道飞行航空飞机哥伦比亚号获得了现时代巨大功率的加铝粉的助推器。 105米长的助推火箭在其固体燃料中加入铝粉,使其产生2900吨的推力,把2200吨航天机体推离发射台。175吨铝粉的与氧化剂混合制成1000吨固体燃料供两台助推器使用。两分钟燃烧之后升到43公里高空时助推火箭与航天飞机分离(见模拟图)。火箭带着降落伞溅落在海洋中,以备回收和下次发射航天飞机时再用。 Alcoa公司粉材销售经理说,铝粉是固 The world’s first orbital flight aircraft, the Columbia No. 1, received the booster of the aluminum powder power of the current era. The 105-meter-long booster rocket added aluminum powder to its solid fuel, generating 2,900 tons of thrust, pushing the 2,200-ton spacecraft off the launch pad. 175 tons of aluminum powder is mixed with an oxidizer to make 1,000 tons of solid fuel for use by two boosters. After two minutes of combustion, the booster rocket was separated from the space shuttle when it rose to an altitude of 43 kilometers (see simulation). The rocket landed in the ocean with a parachute and was ready for recovery and reuse when it was next launched. Alcoa powder material sales manager said that aluminum powder is solid
