Witryna19 kwi 2024 · This image was created using data from a computational fluid dynamics simulation – essentially a virtual wind tunnel test. The red and orange areas represent higher drag, and the green and blue areas represent lower drag. Note the beautifully sleek green-blue color of the wings – the colors of Earth.
