巧妙的工程设计使土星V火箭有效载荷能力逐步提高了4000多磅。由于月球过渡轨道有效载荷所增加的重量在价值上至少要比同样重量的黄金贵五倍,因此就很有必要详细研究获得有效载荷增量所采取的具体技术措施。补加燃料,采用推进剂利用系统,选择轨道形状,和选用按程序调节混合比的方法可以减少剩余推进剂,速度损失和性能偏差所起的有害影响,从而可以提高火箭的性能。本文综述了这些方法,而且还论证了补加燃料所用的传统力矩平衡法,从概念上解释了按程序调节混合比以提高有效载荷重量的方法,并介绍了再现飞行中火箭推力和液流变化规律的精确计算方法。
Ingenious engineering has enabled Saturn V rocket payload capacity to gradually increase over 4,000 pounds. Since the added weight of the lunar transitional orbit payload is at least five times more valuable than the same weight of gold, it is necessary to examine in detail the specific technical measures taken to obtain incremental payloads. Refueling, the use of propellant systems, the choice of orbital shapes, and the choice of program-adjusted mixing ratios can reduce the detrimental effects of remaining propellants, speed losses, and performance deviations, thereby improving rocket performance. This article reviews these methods and demonstrates the traditional method of torque balancing for refueling, explaining conceptually the method of adjusting the mixing ratio to increase the payload weight, and describes the rocket thrust and flow variations in the reproduced flight Accurate calculation of the law.
