Recent scientific studies have established that the addition of tubercles to the leading edges of airfoils directly addresses the fundamental limitations of conventional aerodynamic performance. The image above was produced in a flow study and it demonstrates how tubercles manage aerodynamic flow.

  • Tubercle airfoils display enhanced stable lift.
  • Even at high pitch angles, they keep drag low.
  • They dramatically improve stall angle (pitch) performance.
  • Tubercle airfoils deliver stable operation over an unmatched range of pitch angles and better still, when they do stall, they stall gradually. They literally revolutionize low speed performance far beyond any conventional blades.
