Скачать или смотреть Helicopter Rotor Disk Flow Visualization in a Wind Tunnel

This high-speed wind tunnel test reveals the complex three-dimensional flow field generated by a helicopter rotor system. Wind tunnels are typically constructed as entirely black chambers to eliminate light absorption and prevent shadows or reflections that could impact data accuracy. While these conditions can create significant imaging challenges, Phantom high-speed cameras are designed to overcome these constraints, revealing the intricate aerodynamic phenomena critical to rotorcraft performance.

This visualization, for example, demonstrates fundamental helicopter physics as the rotor accelerates air downward to produce upward thrust. The complex vortex patterns directly influence performance parameters, including power requirements and vibration levels. Such data enables engineers to optimize blade geometry for better fuel efficiency, reduced noise footprint and enhanced flight characteristics.

The video was filmed with the following specifications:
● Phantom VEO4K 990
● 938 frames per second (fps)
● 4096 x 2160 resolution
