摘要
为了掌握飞机拦阻过程的动态系统特性,以便优化飞机拦阻系统设计,本文针对某型飞机拦阻系统进行了数学建模分析,从水涡轮吸能器的运动特征出发,提出了一种定常阻尼载荷理论分析方法.利用该方法预测某型飞机撞网后的飞机速度、飞机过载、拦阻带拉力的发展趋势与试验结果基本吻合,飞机最大过载和拦停距离的偏差均为+1.7%,验证了该理论分析方法的可靠性.
Abstract
In order to understand the dynamic system characteristics of aircraft interception process to a-chieve better arresting performance,a mathematical modeling analysis of a certain type of aircraft arrest-ing system was studied,and a theoretical analysis method for steady-state damping load based on the motion characteristics of water turbine absorbers was proposed. The data of this method to predict the de-velopment trend of aircraft speed,aircraft overload,and arresting belt tension after a certain type of air-craft collides with the net was basically consistent with the experimental results. The deviation of the max-imum overload and stopping distance of the aircraft was+1.7％,which verified the reliability of this theoretical analysis method.
