The use of multi-domain modeling technology enables detailed modeling of the flight dynamic and landing gear dynamic. The simulation results show that the aircraft landing gear system mathematical model established appropriately reflects the change of force and moment in the process of taking off and landing  and it is actual in the physical process. The parameter design space is easily searched by considering a number of different landing scenarios to optimize the design. the authors.   双层星座中负载均衡路由协议研究 期刊论文  OAI收割 宇航学报, 2012, 卷号: 33, 期号: 6, 页码: 746-753 陈建州; 王路; 刘立祥; 胡晓惠 收藏  |  浏览/下载：44/0  |  提交时间：2012/11/12 Aerospace engineering  Space flight   Experimental Study and Numerical Simulation of Two-phase Flow on water-vapor separator in Space 会议论文  OAI收割 Asian Microgravity Pre-Symposium 9th China-Japan-Korea Workshop on Microgravity Sciences, 中国广西桂林/Guilin, China, 2012-10-29 作者:  Li ZG(李章国);  Liu QS(刘秋生);  Qiu RH 收藏  |  浏览/下载：189/0  |  提交时间：2014/04/02 water  phase  liquid  Numerical  separator  Experimental  weightlessness  vapor  Space  residual  distribution  obtained  flight  results  regenerative  urine  roller  features  extended  design   Nostoc sphaeroides Kutzing, an excellent candidate producer for CELSS 期刊论文  OAI收割 ADVANCES IN SPACE RESEARCH, 2011, 卷号: 48, 期号: 10, 页码: 1565-1571 作者:  Hao, Zongjie;  Li, Dunhai;  Li, Yanhui;  Wang, Zhicong;  Xiao, Yuan   |  收藏  |  浏览/下载：27/0  |  提交时间：2011/12/22 Celss  Producer  Nostoc Sphaeroides Kutzing  Food  Space Flight   A strong coupled CFD-CSD method on computational aeroelastity (EI CONFERENCE) 会议论文  OAI收割 2011 2nd International Conference on Mechanic Automation and Control Engineering, MACE 2011, July 15, 2011 - July 17, 2011, Inner Mongolia, China Xi R.; Jia H. 收藏  |  浏览/下载：67/0  |  提交时间：2013/03/25 In this paper  a strong coupled CFD-CSD method is developed to simulate the aeroelastic phenomena. 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.
