Cross section of the Panda control foil with air feed slots at 15% of the chord length
Cross section of the Naca Control foil (original geometry) with air feed slots
at 50% of the chord length
Cross section of the Naca Control foil(modified geometry) with air feed slots
at 50% of the chord length
Cross section of the take-off foil with air feed slot at the trailing edge
Cross section of the Strut foil with air feed in the leading and the trailing edges
as well as in the pressure and suction sides
These profiles evolved using typically two main tools interlinked:
1. profile calculation potential flow with boundary layer and separation bubble configuration (surfaces with constant static pressure)
2. experimental validation in high-speed cavitation tunnel at IMHEF Swiss
