印度空间研究组织于7月18日从斯里哈里科塔发射场用自制的SLV-3火箭把35公斤重的“光明”卫星送入轨道。这是印度在空间技术上取得的重要突破。 SLV-3火箭是一枚用全固体燃料作动力的四级火箭,连同卫星的重量一共为17吨,其中燃料有14吨。火箭头两级发动机的外壳由金属制成,而第三、四级发动机的外壳则是由纤维增强塑料制成。整个火箭有十万多个元件,使用的扣件大约有4万个,其电子设备包括800
On July 18, the Indian Space Research Organization (ISRO) sent 35 kilograms of “bright” satellites to orbit using a homemade SLV-3 rocket from the Sriharikota launch site. This is an important breakthrough made by India in space technology. The SLV-3 rocket is a four-stage rocket powered by all-solid fuel, with a total weight of 17 tons of satellites, including 14 tons of fuel. Rocket two engine shell made of metal, while the third and fourth engine shell is made of fiber-reinforced plastic. The entire rocket has more than 100,000 components, about 40,000 fasteners used, and its electronics include 800
