叶轮机械综合实验课线上线下混合教学探索与实践

叶轮机械是航空发动机以及能源动力系统的关键部件,在国家积极推进“航空发动机和燃气轮机重大专项”的背景下,立足本校学情,对专业实验课叶轮机械综合实验的教学模式进行探索与实践。通过对目前叶轮机械实验课程的教学情况进行分析,根据线上线下混合式教学理念及其教学模式优势,针对所提出的问题,对实践课混合教学模式进行研究与探索。该教学方法探索全方位解决学生在课前预习、课堂实验操作及课后实验报告这三个主要环节中存在问题的途径,并且解决传统高速跨声速叶轮机械实验受安全限制无法线下开展的问题。通过线上线下混合式教学模式的实施,不仅保留传统实验教学的实际操作体验,而且将信息化网络化创新带入实验课堂,进一步优化当前的叶轮机械实验课教学模式,提升实验教学的新高度。

Turbomachinery is a key component of aviation engines and energy power systems.Against the backdrop of the country's active promotion of the"Major Special Project for Aviation Engines and Gas Turbines",based on the academic situation of our school,we explore and practice the teaching mode of the professional experimental course"Comprehensive Experiment of Vane Machinery".By analyzing the current teaching situation of impeller machinery experimental courses,based on the concept of blended online and offline teaching and the advantages of the teaching mode,research and exploration are conducted on the blended teaching mode of practical courses in response to the problems raised.This teaching method explores ways to comprehensively solve the problems that students face in the three main stages of pre class preparation,classroom experimental operations,and post class experimental reports.It also solves the problem of traditional high-speed transonic turbomachinery experiments being unable to be conducted offline due to safety restrictions.The implementation of a blended online and offline teaching mode not only preserves the actual operating experience of traditional experimental teaching,but also brings information and network innovation into the experimental classroom,further optimizing the current teaching mode of impeller machinery experimental courses and elevating experimental teaching to a new height.
