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，需要显着提高指向精度。因此，委员会建议，准确地预测天线在外场工作条件下的结构动态响应，特别是空气动力载荷和阵风湍流，对天线的结构和系统设计是非常重要的。这些信息对于研制一种能够在可持续指向的情况下达到设计要求的鲁棒控制系统也是必不可少的。需要进行研究，以开发我们的工业合作伙伴正在开发的大型高精度地面天线的高保真动态气动弹性模型。动态气动弹性模型将被用来进行广泛的动态气动弹性响应分析的天线，以确定其结构的动态特性，系统接口响应以及相应的瞬态指向精度在恶劣的环境条件下。然后将所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，以最大限度地提高指向精度并最小化天线重量。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.
