阿里安4是欧洲阿里安运载火箭系列中性能最高、样式最新的运载火箭。为满足多方适应能力的要求,需要设计大型固体助推器(每个助推器装9.5吨推进剂,而阿里安3的每个助推器只装7.3吨推进剂)。安装在运载火箭上的助推器,一般是2个或4个或者是与其它附加的液体助推器组合安装,能提供的最大地球同步转移轨道有效载荷能力为4.3吨。固体助推器的总冲量为22000千牛·秒,最大推力为745千牛,由意大利的克菜费洛SNIA-BPD(防御与宇航分部)研制和鉴定。研制计划于1983年1月开始,并于1985年9月成功地通过了鉴定。本文描述了该助推器的方案并叙述了其设计方法。特别讨论了如何以最小的改动,把阿里安3的经验和试验结果应用到阿里安4固体助推器的最后方案中,以实现一个成本效益高的计划。文中还详细介绍了研制和鉴定试验的结果。
Arian 4 is the highest performance, style of the newest launch vehicle in the European series of Arian launch vehicles. In order to meet the requirements of multifaceted adaptability, large solid boosters (9.5 tons of propellant per booster, and 7.3 tons of propellant per Ariane 3) are required. Boosters mounted on launch vehicles, typically 2 or 4 or in combination with other additional liquid boosters, provide a maximum geosynchronous orbit payload capacity of 4.3 tonnes. The total thrust of the solid booster is 22,000 kN · s and the maximum thrust is 745 kN, developed and certified by the Italian Krusefero SNIA-BPD (Defense and Aerospace Division). The development plan began in January 1983 and successfully passed the appraisal in September 1985. This article describes the booster solution and describes its design methodology. In particular, it discusses how to apply the Triumph 3 experience and test results to the final solution of the Allianz 4 Solid Boosters with a minimum of modifications to achieve a cost-effective plan. The article also describes in detail the results of research and qualification tests.
