摘要

经过多年的发展，高保真概念设计和结构优化(HCDstruct)工具正在扩展到支持先进飞机概念的动态气动伺服弹性分析和结构优化。这些需要的改进包括:开发空气动力学匹配程序，以纠正Nastran的双晶格空气动力学方法;控制面结构模型的实现;实现对Nastran颤振解序列(SOL 145)的支持。本文提出了一个更新的实现广义控制面结构模型和支持Nastran SOL 145

Update on the Development of a Flutter Analysis Capability for Unconventional Aircraft Concepts using HCDstruct

Following years of development, the Higher-ﬁdelity Conceptual Design and structural optimization (HCDstruct) tool is being extended to support dynamic aeroservoelastic analysis and structural optimization for advanced aircraft concepts. These required enhancements include: the development of an aerodynamic matching routine for correcting Nastran’s doublet-lattice method aerodynamics; the implementation of control surface structural models; and the implementation of support for Nastran’s ﬂutter solution sequence (SOL 145). This paper presents an update on the implementation of generalized control surface structural models and support for Nastran SOL 145
