Development of Engine Maintenance and Test Run Experiment Resource for Digital Twin
To address the restrictive factors such as the high maintenance cost of aircraft engine and systems,and limitations of the maintenance workshop and the hazards,this article constructs the experimental resources for civil en-gine maintenance and commissioning based on the digital twin with VR/AR/MR technology,and proposes the overall design framework structure,including the VR end with Leap Motion and MR end design scheme.With the help of hel-met display and gesture control equipment,the technologies of registration tracking,gesture recognition,virtual and real fusion,and voice interaction allow students to interact with virtual objects in a digital environment so that the user gets an immersive sense of experience in a converged environment.Finally,with an aero-engine component as an ex-ample,the feasibility of digital twin and 3R technology in civilian engine maintenance training is displayed.
