During my time at NLR I worked on several VCNS projects in Unity 3D.

The NLR Virtual Community Noise Simulator (VCNS) is an innovation to support airport communities and other stakeholders who want to experience aircraft noise in their own environment by using the latest virtual reality technologies with 360 degrees video and 3D audio experience. New aircraft types and new procedures can be examined and presented at any location before they are implemented or planned.

One of the projects I did was implementing a simulation for the Pipistrel Velis Electro. The Pipistrel Velis Electro is a two-seater all-electric aircraft designed and manufactured by Pipistrel, a Slovenian aviation company. It is the world's first type-certified electric airplane and is designed for pilot training and recreational flying.
With the VCNS simulation the audience could experience the difference in noise during
fly-over with a conventional small aircraft and the fully electric Pipistrel.
