低雷诺数下小型无人机翼型气动特性分析
Aerodynamic Characteristics Analysis of the Small Unmanned Aerial Vehicle's Airfoil at Low Reynolds Numbers
摘要
Abstract
Based on the research of small UAV,numerical simulations of the flow over airfoil CLARKY Re=1.0×105、5× 105、1.0×106were used to analyze the aerodynamic performances -5°~20° in a range of low Reynolds numbers with the transition model eNof linear stability theory.The results showed that the airflow separation was gradually transformed into a laminar separation bubble structure from completely separation,while the transition position on the upper surface of the airfoil was moved toward leading edge continuously with the increase of Reynolds number,and the aerodynamic character?istics of airfoil CLARKY was gradually improved.关键词
