斜置飞翼翼型气动性能的研究

Research on the Aerodynamic Performance of OFW Airfoil

斜置飞翼是一种具有亚音速和超声速巡航能力的可变后掠角飞机。本文根据斜置飞翼的飞行特点和气动特性,选用了相对弯度、相对厚度等参数不同的两种翼型。通过数值模拟分析,对比两种翼型在不同迎角和雷诺数下的空气动力性能,结果表明翼型2的气动性能优于翼型1。

Oblique flying wing with subsonic and supersonic cruising ability of variable sweep aircraft.According to the characteristics and aerodynamic properties of oblique llying wing, selected two different kinds of te airfoil with relalive camber, relative thickness of parameters. Based on rmmerical simulation, in comparison to the two airfoil aerodynamics at different angles of attack and Reynolds number, the resuhs show that the wing Type 2 airfoil aerodynamic performance is better than type I.
