内容大纲
气动声学既是一门流体与声学交叉的基础技术学科，又是一门紧密结合航空飞行器及其推进系统研发设计的应用学科，有着显著的工程应用背景。因此，如何将复杂的飞行动力系统中声音的产生、传播和辐射凝练成基础科学问题，并从中获得物理机制的理解和认识，是本书主要的写作目的。本书按照气动声学作为基础学科的发展过程为背景，结合航空推进器关键气动声学问题，构建了从基础研究到工程应用快速预测方法的知识体系，其中包括气动声学的基本定律、快速计算模型、不同类型的流体与物面边界干涉等发声问题的物理建模、并结合发动机主要噪声部件阐明了声音的来源和传播特性。
本书可以作为气动声学课程讲义，也可以作为具有基础流体力学和声学基础知识的研究生自学材料，更可以成为参与型号研制的航空工程师学习调研的重要参考资料。
