Israel Wygnanski‘s active flow control systems may well be pushing the aircraft industry to the brink of the next major shift in design.
Wygnanski has been developing, testing and perfecting active flow control technology for 40 years. For the last four years, he has worked with Emilio Graff, director of the Lucas Wind Tunnel at the California Institute of Technology, creating active flow control technology that promises to usher in smaller, lighter, quieter, more efficient airplanes. Active flow control refers to the manipulation of a flow field – through the addition of energy – to improve the performance of a solid body moving in a fluid, such as an airplane moving through the air.
