航空发动机虚拟教学实验系统的建设与应用

Construction and Application of Aero-engine Virtual Teaching Experiment System

本文通过虚拟现实技术构建了航空发动机虚拟教学实验系统,能够实现发动机模拟装配、发动机结构展示、发动机工作机理演示、发动机模拟试车等功能。系统通过三维交互、视景仿真等手段,使学生获得视、听、触等感知体验,具有很强的交互性与沉浸感。发动机虚拟教学实验系统有效的克服了传统教学实验成本过高、操作困难等问题,对促进我国航空动力技术人才培养具有重要意义。

This paper, through virtual reality technology, constructed a aero-engine virtual teaching experiment system which can achieve the functions of engine simulation assembly, engine structure display, engine working mechanism demo, engine simulation test. Through the three-dimensional interaction and visual simulation means of this system, the students can get the vision, hearing, touch and other sensory experiences, with a very strong interaction and immersion. Engine virtual teaching experiment system effectively overcome the high cost, operational difficulties and other issues of traditional teaching experiment, so it has great significance to the promotion of China＇s aviation technical personnel training.
