Aero-engine intake aerodynamic design and analysis

克兰菲尔德大学以前的工作已经为吊舱式发动机构型的进气道气动管路设计开发了方法。这些工具正在扩展到三维配置的最终目标是开发一个可行的未来超高涵道比配置的短进气道。该研究包括优化方法的开发，以及包括使用低阶风扇模型的风扇和进气道之间的相互作用。博士研究的总体目标是开发与未来超高涵道比发动机配置的风扇系统相关的短进气道设计工具和设计指南。（可选）评估进气道流线设计对新参数化方法的敏感性。开发设计指南数据库，用于快速确定初始参数设置，以便进行后续优化。研究几何参数、空气动力特性和进气道性能指标之间的关系，确定是否可以根据建议的参数化方法为进气道扩压器性能和空气动力特性建立有用的设计准则，研究减少气动优化计算要求的方法，例如通过响应面法、简化几何参数化或多保真度方法。

Previous work at Cranfield University has developed methods for the design of intake aero-lines for podded engine configurations. These tools are being extended to three-dimensional configurations with the ultimate aim of developing a viable short intake for future ultra-high bypass ratio configurations. This related research encompasses the development of optimization methods as well as including the interaction between the fan and the intake using low-order fan models.The overall aim of the PhD research is to develop tools and design guidance in the design of short intakes in association with fan systems for future ultra-high bypass engine configurations.Expanded definition of research project (optional)Assessment of intake aero-line design sensitivity to new parameterization method.
