SES AR vs ∫dx

SES AR is an app designed to inspire and educate schoolchildren about the exciting possibilities of a career in Science, Technology, Engineering and Mathematics (STEM) and in teaching them about the practical uses of virtual and augmented reality in the world of work. In addition, for engineers, the app provides a clear example of how augmented reality can be used to bring complex concepts to life. It demonstrates an engineering procedure Rolls-Royce has developed to transport the Trent XWB by air freight when no other transportation options are viable. The procedure involves the separation of the core engine from the LP compressor fancase using dedicated engine separation and transportation stands. Learn more about the procedure by interacting with a 3D model in both simulated and augmented reality!
