1984年美国在空间、战术、战略固体火箭推进技术方面有以下一些成就:航天飞机航天飞机的固体发动机,飞行性能仍然良好。发动机部件的回收、修复和重复使用,仍然达到了预期要求,有些部件已经飞行了三次。石墨纤维缠绕壳体的开发工作已取得相当大的进展。航天飞机固体助推器如使用这种壳体,可使从范登堡美国空军基地发射到低地球轨 In 1984, the United States made the following achievements in space, tactical and strategic solid rocket propulsion technologies: the space shuttle’s solid-state engine has good flight performance. Recycling, repairing and reusing engine components still met the expected requirements and some components had flown three times. The development of graphite fiber wound shell has made considerable progress. Space Shuttle Solid Boosters Using this enclosure allows launching from Vandenberg U.S. Air Force base to low Earth orbit
