Exploration of Multi-level Hybrid Practical Teaching Surrounding Nozzle
In order to fully adapt to the construction of new engineering disciplines in the aerospace industry under the background of aerospace integration and the training needs of"two types"talents in the aircraft power engineering major of National University of Defense Technology,the nozzle is selected as the core component of aerospace power equipment,and a multi-level and hybrid practical teaching reform exploration is carried out in the course of"Jet Propulsion Principles".We independently design and construct a four-level practical teaching system,including a basic cognitive experiment on the principle of nozzle thrust generation,a comprehensive training experiment on nozzle working condition adjustment and observation,a virtual simulation experiment on nozzle flow process,and an innovative practice routine of"big homework+innovation training+academic competition+graduate design".Four stage teaching objectives is achieved including"familiarizing with nozzle performance indicators,understanding nozzle testing methods,understanding nozzle working principles,and mastering nozzle design methods".Students effectively strengthen their understanding of nozzle principles,deepen their understanding of the similarities and differences of various power devices,and achieve significant results in cultivating innovative abilities.The concept of"integrating space and space"becomes more deeply ingrained in people's hearts.
