The origins, development, implementation, and application of AEROM, NASA's patented reduced-order modeling (ROM) software, are presented. Full computational fluid dynamic (CFD) aeroelastic solutions and ROM aeroelastic solutions, computed at several Mach numbers using the NASA FUN3D CFD code, are presented in the form of root locus plots in order to better reveal the aeroelastic root migrations with increasing dynamic pressure. The method and software have been applied successfully to several configurations including the Lockheed-Martin N+2 supersonic configuration and the Royal Institute of Technology (KTH, Sweden) generic wind-tunnel model, among others. The software has been released to various organizations with applications that include CFD-based aeroelastic analyses and the rapid modeling of high-fidelity dynamic stability derivatives. Recent results obtained from the application of the method to the AGARD 445.6 wing will be presented that reveal several interesting insights.
本文介绍了美国国家航空航天局（NASA）获得专利的降阶建模（ROM）软件AEROM的起源、开发、实施和应用。使用NASA的FUN3D计算流体动力学（CFD）代码，在几个马赫数下计算得到的完整CFD气动弹性解和ROM气动弹性解，以根轨迹图的形式呈现，以便更好地揭示随着动压增加气动弹性根的迁移情况。该方法和软件已成功应用于多种构型，包括洛克希德·马丁公司的N+2超音速构型和瑞典皇家理工学院（KTH）的通用风洞模型等。该软件已发布给多个组织，其应用包括基于CFD的气动弹性分析以及高保真动态稳定性导数的快速建模。还将展示该方法应用于AGARD 445.6机翼所获得的最新结果，这些结果揭示了一些有趣的见解。
