利用格壁安装角对栅格舵展开折叠压心控制的工程方法研究探索

随着技术的发展，在工程设计中，对于巡航迎角下栅格舵导弹的展开与折叠的压心变化控制对于控制系统来说尤为重要。本文创新性的首次提出利用栅格舵的内壁单元的偏转，即相对于水平面的夹角来实现在设计点下的压心控制。由于设计过程需要多次迭代，本文利用计算在所关注的设计点处对展开折叠压心进行了验证，创造性的利用了等效代替的方法提出了一种新型的计算折叠状态压心的快速工程方法。

Using the Fixing Angle of Gridfin＇s Wall to Study the Engineering Methods of Controlling Pressure Center in State of Replicating and Deploying

With the developing of technology, in the design of engineering, gridfin＇s replicating and deploying which leads to pressure center＇s change in the state of cruising is very important to controlling system. This articles bring forward using the deflexion of gridfin＇s wall, comparatively to horizontality＇s angle, to realize the adjusting of pressure center at the design point. Because of many times circulations in the design of engineering, this articles using CFD＇s means to validate the pressure center of replicating and deploying at the design point, creatively using a way which could equivalently replace, to bring forward a new CFD method for replicating and deploying in a speedy engineering way.
