Development of Engine Maintenance Technology with Mixed Reality-Taking Pratt & Whitney JT9D as an Example

The engine is the heart of aircraft and deeply affects performance, flight safety, airline management, which makes it a critical component requiring maintenance. With advancement technology, augmented reality (AR), virtual (VR), mixed (MR) technologies have been introduced one after another. To increase maintenance skill ability, important to train for aviation Therefore, (EMMR) system was developed through technology in this study. There are three different scenarios EMMR making easy. In first scenario, an exploded diagram disassembled with main components has made animation fuel flow demonstrated introduce basic structure engine. second interactive buttons animations used simulate removal from wing airplane so that users can understand process disassembling third hybrid implemented interact objects, could disassembly replacement fan blades get familiar whole process. Students familiarized Microsoft HoloLens 2 survey conducted before using if currently help students each general classroom make learning more efficient at same time.
