DARcorporation engineers have been researching and testing propeller design methods to improve propeller performance for existing and conceptual commercial multicopters/drones. A 2-bladed propeller model was created using an in-house design code and analyzed in CFD. The simulations have modeled 2D and 3D streamlines and vorticity in three dimensions. An octocopter drone concept was also simulated to observe its behavior in forward flight. This image may look familiar because it was chosen as a winner by then-CD-adapco to appear on their 2016 calendar for the month of April.
