Simulation and fabrication of bionic sharkskin composite micro-nano wind resistance reduction structure

  • 摘要: 仿生学与减阻技术的结合,为减阻开辟了重要的研究方向,在航空航天领域有着潜在的发展与应用前景。为提升降低风阻效果,本文对复合微纳减风阻结构进行了研究,基于仿生学原理,采用CFD仿真以及激光微纳制造技术,建立了减阻结构组合模型,并在飞行器的大气传感器半球头体模型表面制造仿生鲨鱼皮复合微纳结构,即在仿生鲨鱼皮鳞片结构的基础上,通过激光干涉扫描二级微沟槽,以进一步提升减阻效果。采用仿真模拟与风洞实验相结合的方式,对减阻机理进行理论分析,完成了复合结构的微纳制造,减阻率最高可达10.3%。
