Catto Propellers Active Flow Analysis

In 2013 Catto Propellers began to develop a method to record the dynamic air flow of a propeller in flight. With a custom mount made by Saber Manufacturing and a vacuum formed carbon fiber case to house the GoPro, we were able to maintain a live feed on the propeller aerodynamics. The GoPro Hero 3+ with 60 frames per second, 1080p, provided a real time visual throughout the flight profile that allowed Craig Catto to improve the propeller efficiency by actively notating where it is possible to reattach flow and modify the airfoils accordingly, ultimately improving the performance of the blade, in all aspects. It's been this type of continuous improvement that has led to Catto's achievement of numerous world records and recognition of advanced propeller design.
