可变形飞行器的优越性,使其成为近年来研究者关注的热点。当前对于可变形飞行器气动方面的研究工作主要集中于采用数值模拟或风洞实验,开展可变形飞行器气动布局概念和不同变形模态气动特性研究,而关于连续变形过程中非定常气动特性的研究则很少,几为空白。本文在无粘不可压(Ma=0.2)流场中,数值模拟了儒可夫斯基翼型连续改变厚度、弯度所引起的气动特性变化,分析了不同变形幅度、变形速度以及变形加速度对非定常升力系数的影响情况,这也为以后的三维数值模拟提供了基础。
The superiority of deformable aircraft makes it a hot spot for researchers in recent years. At present, the researches on the aerodynamics of deformable aircraft mainly focus on numerical simulation or wind tunnel experiments, and the concept of aerodynamic layout of deformable aircraft and the aerodynamic characteristics of different deformation modes are studied. However, the study of unsteady aerodynamic characteristics in continuous deformation Few, a few blank. In the non-viscous and incompressible (Ma = 0.2) flow field, the aerodynamic characteristics caused by the continuous change of the thickness and the camber of the Rukowski wing are numerically simulated. The influences of different deformation amplitudes, deformation velocities and deformation accelerations on the non- The influence of constant lift coefficient, which also provides the foundation for the future three-dimensional numerical simulation.
