Dynamic Aeroelasticity Response Analysis and Pointing Accuracy Assessment of High Precision Ground Antennas Subject to Aerodynamic Gust

InterTronic Solutions Inc.设计和制造高精度地面天线，工作在非常高的无线电频率，这需要显着提高指向精度。因此，准确预测天线在野外工作条件下的结构动态响应，特别是气动载荷和阵风湍流对天线的结构和系统设计具有重要意义。这些信息对于能够实现可持续指向精度的设计要求的鲁棒控制系统的开发也是必不可少的。我们的工业合作伙伴正在开发一种大型高精度地面天线，需要研究开发一种高保真动态气动弹性模型。动态气动弹性模型将用于对天线进行广泛的动态气动弹性响应分析，以确定其结构动态特性，系统界面响应以及在恶劣环境条件下相应的瞬态指向精度。然后将开发的动态气动弹性模型集成到多尺度拓扑设计优化框架中，以最大化指向精度和最小化天线重量。预计这项研究的结果将降低天线的瞬态操作限制，并为InterTronic Solutions产品的新应用和客户打开大门。

InterTronic Solutions Inc. designs and manufactures High precision ground antennas operating at very highradio frequencies which require a significantly increased pointing-accuracy. Accordingly, an accurateprediction of the antenna's structural dynamic response to field operating conditions with particular emphasison aerodynamic loads and gust turbulence is of great importance to the antenna's structural and systems design.This information is also essential for the development of a robust control system capable of achieving designrequirement with sustainable pointing-accuracy.Research is required to develop a high fidelity dynamic aeroelastic model of a large high precision groundantenna that is being developed by our industrial partner. The dynamic aeroelastic model will be used toconduct an extensive dynamic aeroelastic response analysis of the antenna to determine its structural dynamiccharacteristics, systems interface response as well as corresponding transient pointing-accuracy under severeenvironmental conditions. The developed dynamic aeroelastic model will then be integrated into a multiscaletopology design optimization framework to maximize the pointing-accuracy and minimizing weight of theantenna. It is expected that the outcome of this research will reduce transient operational limits of the antennaas well as opening the door for new applications and customers for products of InterTronic Solutions.
