Performance of ground based scrubbing inerting of unmanned aerial vehicle fuel tank

  • 摘要: 提出了无人机油箱地面洗涤惰化技术理论和方法,利用CFD方法研究了采用地面洗涤惰化技术降低油箱气相空间氧体积分数并使无人机油箱在地面和飞行条件下仍然保持惰化状态的可行性。利用volume of fluid(VOF)两相流模型和自定义传质方程计算了不同油箱初始氧体积分数和载油率下气相空间氧体积分数的变化情况,结果表明:在相同的飞行时间,气相空间氧体积分数随着初始载油率和油箱初始氧体积分数的增加而增加;当油箱初始氧体积分数不高于2%,且初始载油率不高于50%时,飞行过程中油箱气相空间氧体积分数始终低于9%,满足军用飞机油箱惰化要求。研究可为无人机油箱地面洗涤惰化边界设计提供参考。
