本文对响尾蛇导弹弹体改型提出了一个飞行性能改善的初步估计。具体地说,对阻力减小的范围、高控制力矩的减小和鸭翼正向横滚和横滚速率控制都进行了叙述。通过对原来的的响尾蛇及其改型的飞行性能的比较,进行了性能改善的评价。并且对控制力矩大小的初步估算和可用的横滚控制也作了说明。 In this paper, a preliminary estimation of flight performance improvement for a rattlesnake missile projectile is proposed. Specifically, the scope of the drag reduction, the reduction of high control torques and the control of the roll roll roll roll and roll rate are described. The performance improvement was evaluated by comparing the original rattlesnake and its modified flight performance. The preliminary estimation of the control torque and the available roll control are also described.
