欧洲空间局研制的“阿里安-1”运载火箭于一九七九年十二月二十四日在法属圭亚那库鲁靶场发射成功,命名为LO1。由欧空局和法国空间研究中心提供的基本技术指标如下: 火箭全长47.388米,第一级点火时的重量为210,269公斤。第一级结构重量13,319公斤,装有147,567公斤推进剂(肼和四氧化二氮)。四台“海盗5”型发动机的总推力为249,000公斤。第二级结构重量3,900公斤(包括1/2级的过渡级),装有和第一级同样的推进剂34,093公斤,带有一台“海盗”式发动机,总推力为68,947公斤。
The “Ariane-1” launch vehicle, developed by the European Space Agency, was successfully launched on December 24, 1979 at the Kourou Range in French Guiana, and was named LO1. The basic technical indicators provided by ESA and the Center for Space Studies of France are as follows: The rocket is 47.388 meters in total length, with the first stage weighing 210,269 kg upon ignition. The first-stage structure weighs 13,319 kilograms and contains 147,567 kilograms of propellants (hydrazine and nitrous oxide). The total thrust of the four “Pirate 5” engines is 249,000 kg. The second-stage structure, weighing 3,900 kg (including a 1/2 level transitional stage), contains 34,093 kg of the same propellant as the first stage and has a “pirate” engine with a total thrust of 68,947 kg.
