阿里安—3是欧洲阿里安运载火箭增加两台捆绑式固体助推器后的改型。通过改型使它运送有效载荷至同步转移轨道的能力从2175kg增至2580kg。该助推器由意大利SNIA—BPD公司防卫和宇航分部研制与鉴定。每台装药量为7.3t,最大推力730kN。本计划于1979年开始,1984年8月首次飞行成功。本文介绍了助推器的构型,以及设計、研制、鉴定的各主要阶段,并将首次飞行数据与鉴定试验数据作了比较。
Ariane-3 is a variant of the European Arian carrier rocket after adding two bundled solid booster. The ability to transfer payloads to the synchronic orbit by retrofitting increased from 2175 kg to 2580 kg. The booster by the Italian company SNIA-BPD Defense and Aerospace Division developed and identified. Each charge is 7.3t, maximum thrust 730kN. The project started in 1979 and was first successful in August 1984. This article describes the configuration of the booster, as well as the major stages of design, development, and qualification, and compares first flight data with qualification test data.
