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.
