Dual airfoil testing system

A dual airfoil testing system comprising:

• a platform comprising:
• a frame defining a chamber, the chamber being oriented to receive a horizontal flow of air;
• a first attack angle stepper motor mounted on the frame;
• a first mount extending from and rotatable by the first attack angle stepper motor and configured to mount a first airfoil in a first position in the chamber;
• a second attack angle stepper motor mounted on the frame;
• a second mount extending from and rotatable by the second attack angle stepper motor and configured to mount a second airfoil in a second position in the chamber;
• at least one gap stepper motor mounted to the frame and configured to move the first attack angle stepper motor in a vertical direction to adjust a gap between the first airfoil and the second airfoil;
• and
• at least one stagger stepper motor mounted to the frame and configured to move the second attack angle stepper motor in a horizontal direction parallel to the horizontal flow of air to adjust a stagger between the first airfoil and the second airfoil;
• wherein actuation of the first attack angle stepper motor rotates the first airfoil on a first horizontal axis perpendicular to the horizontal flow of air to adjust a first attack angle of the first airfoil;
• wherein actuation of the second attack angle stepper motor rotates the second airfoil on a second horizontal axis perpendicular to the horizontal flow of air to adjust a second attack angle of the second airfoil;
• wherein actuation of the at least one gap stepper motor translates the first airfoil in the vertical direction to adjust the gap between the first airfoil and the second airfoil;
• and
• wherein actuation of the at least one stagger stepper motor translates the second airfoil in the horizontal direction parallel to the horizontal flow of air to adjust the stagger between the first airfoil and the second airfoil.
