Research on Design of Low Reynolds Number Airfoil Based on DISC Method

The DISC method is suitable for the design and optimization of airfoil, especially in engineering. Low Reynolds number airfoil design has been conducted using DISC method, coupled with N-S equations. Detailed DISC theory and equations have been elaborated. The effectiveness of the method is validated by choosing the FX63-137 airfoil as the initial airfoil, and the NACA0012 as the target. A low Reynolds number airfoil profile is obtained using the method by giving a favourable target pressure distribution. Results show that its aerodynamic characteristics in low Reynolds number are satisfactory. The transition location of the airfoil is about 60% of the chord length, which means it has wide laminar flow range and is suitable for near space vehicles.
