1985年是固体火箭技术在航天应用方面非常活跃的又一个年份。莫顿—锡奥科尔公司进行了两次石墨纤维缠绕壳体发动机的地面试车,证明了这种发动机能把航天飞机的有效荷载能力提高4600磅。这种石墨纤维缠绕壳体是赫克力斯宇航公司制造的。它的最后鉴定试验是在9月份进行的。为了进行定于下一年的首次飞行,该发动机的所有各段已运抵加州的范登堡空军基地。在6月份,航天飞机创造了一项“第一”,当时,麦克唐纳—道格拉斯公司制造的有 1985 is another year in which solid rocket technology is very active in aerospace applications. Morton-Siocco conducted two ground tests on graphite fiber wound shell engines, demonstrating that the engine can increase the space shuttle’s payload capacity by 4,600 pounds. This graphite fiber wound housing is manufactured by Hercules Aerospace. Its final qualification test was conducted in September. All the segments of the engine have arrived at Vandenberg Air Force Base in California for the first flight scheduled for the following year. In June, the space shuttle created a “number one,” when McDonnell Douglas made
