Finally for all the above aeroelastic problems , distributed parallel computation is accomplished 最后对以上气动弹性问题的数值计算进行了基于微机网络的分布式并行计算研究。
The research of this dissertation is focused on how to simulate numerically the steady and unsteady subsonic , transonic and supersonic viscous flows around wing and aircraft by computational fluid dynamics method . on this basis , several kinds of aeroelastic problems of aircraft are investigated 本文的主要工作是利用计算流体力学( cfd )方法,数值模拟机翼和全机的定常及非定常粘性绕流,并在此基础上耦合结构动力学方程研究了飞行器的多种气动弹性问题。
Secondly , the static aeroelastic problems and jig - shape design , as a kind of multi - disciplinary design optimization ( mdo ) , are investigated for sweep wing and super - critical wing . numerical results are in good agreement with other reference data . the method and the program presented in this paper are verified 分别以某后掠机翼和超临界机翼为算例,对机翼的静气动弹性问题以及基于静气动弹性的型架外形优化设计和飞行姿态确定进行研究,计算结果和有关文献的结果进行了比较,吻合很好。
