The CFD solver is based on the finite-volume algorithm for the Navier-Stokes equations on unstructured grid. The CSD solver solves the aeroelastic governing equations in the modal space. Their coupling is realized by a dual-time method. The spring-based smoothing method is adopted to deform and regenerate the aerodynamic grid. Two test cases are selected to validate the authors' method for static and dynamic aeroelastity .The results of the simulation for the static aeroelastic problems of a missile wing show that the Lift Coefficient and Drag Coefficient are severally 7% and 5% lower than those don't consider the elasticity of the wing. The results for the flutter boundary prediction of the AGARD 445.6 wing have been proved much closer to the experiment than using the DLM. This method can describe the effects of fluid viscosity more exactly for highly nonlinear transonic flight conditions. The calculation has proved reliable in the subsonic regime  but not accurate enough in the supersonic regime. 2011 IEEE.   Estimating aerodynamic resistance of rough surfaces using angular reflectance 期刊论文  iSwitch采集 REMOTE SENSING OF ENVIRONMENT, 2010, 卷号: 114, 期号: 7, 页码: 1462-1470 作者:  Chappell, Adrian;  Van Pelt, Scott;  Zobeck, Ted;  Dong, Zhibao 收藏  |  浏览/下载：27/0  |  提交时间：2019/10/08 Dust emission model  Wind erosion  Sheltering  Erodible  Flow separation  Drag  Wake  Aerodynamic resistance  Aerodynamic roughness length  Shadow  Illumination  Ray-casting  Digital elevation model  Roughness density  Frontal area index  Angular reflectance  Bi-directional reflectance   Equivalent lenses of supersonic seeker's outflow refractive index field obtained by simulation and experiment (EI CONFERENCE) 会议论文  OAI收割 2008 International Conference on Optical Instruments and Technology: Optical Systems and Optoelectronic Instruments, November 16, 2008 - November 19, 2008, Beijing, China Qun W.; Hongguang J.; Ming X. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 In order to decrease the aerodynamic drag of supersonic image guide missile and design a non-spherical dome  the outflow field of the missile's dome is simulated using FLUENT. Based on the simulated results  the accurate density field of the outflow field at all kinds of flight conditions is obtained  and then the refractive index field of the outflow field is gotten according to the Gladstone-Dale law. The results show that the shock wave induces the heterogeneity of the refractive index field and the turbulent causes distortion. The outflow field is divided into several zones which are taken as equivalent lenses for aberration analysis. 2009 SPIE.   Aerodynamic characteristics research on wide-speed range waverider configuration 期刊论文  OAI收割 Science in China Series E-Technological Sciences, 2009, 卷号: 52, 期号: 10, 页码: 2903-2910 作者:  Wang FM(王发民);  Ding HH(丁海河);  Lei MF(雷麦芳);  Wang FM;  Wang FM 收藏  |  浏览/下载：876/195  |  提交时间：2009/08/03 Waverider Configuration  Aerodynamic Characteristics At Wide-Speed Range  High Lift-To-Drag Ratio   Improvement of an Aerodynamic Roughness Model With Meteorological Measurements and TM Image 会议论文  OAI收割 Zhou Y.
