The UEC is a Virtual Interactive Environment (VIE) application developed with the Unity game development tool. It is used to support the U.S. Navy Gas Turbine Mechanical Maintenance Core Course. This strategy capitalizes on the inherent strengths of 3D modeling technologies to provide the learner the capability to gain knowledge and proficiency on highly critical tasks using interactive simulations. 3D models deliver the necessary degree of fidelity for interactive simulations and their high reusability allows them to be an economic and low risk alternative prior to the use of real equipment. Improving the muscle memory through repetitions and sets should reduce maintenance downtime and increase the operational hours that U.S. Navy missions require. The UEC provides an Instructor Operation Station (IOS) that allows the Instructor to assign lessons and interactive tasks covering parts familiarization, maintenance procedures, troubleshooting, and remove and replace procedures.
