Airship's longitudinal motion impact analysis based on coupling ballonet

  • 摘要: 高空大型飞艇副气囊体积占比很大,甚至达90%以上,副气囊动力学对飞艇运动产生较大影响。对巡航高度为6 000 m的某大型飞艇,建立基于圆柱容器的副气囊动力学模型,进一步构建考虑副气囊的飞艇纵向耦合动力学方程,并对飞艇纵向运动进行了数值仿真,将其与不考虑副气囊时的结果进行对比。结果表明:副气囊对大型飞艇俯仰运动有较大影响,容易引起运动发散,且耦合影响随飞艇高度增大而变小,同时副气囊体积不变时,其直径越小,动力学耦合效应影响越小;副气囊效应会降低飞艇的操纵性,在进行飞艇设计时应该予以考虑。
