Aerodynamic interaction of fuselage,horizontal stabilator and vertical stabilator of helicopter

  • 摘要: 运用面元法模拟直升机机身流场,计算前飞状态的ROBIN(rotor body interaction)模型孤立机身顶部中线的压力系数分布,并与参考数据、CFD计算结果对比,验证了本方法的准确性.采用离散涡系模拟平尾、垂尾和短翼等升力面,以带短翼的UH-60直升机为例,研究了升力面参数变化对机身、平尾、垂尾气动干扰的影响.结果表明:改变升力面的安装角显著改变了气流对其周围的绕流情况,在参数中影响最大;平尾参数尤其是安装角会对垂尾和短翼的压力系数产生较大影响;减小垂尾展长和增大短翼安装角会提升各自的压力系数.
