WebComparison of CFD data with NACA’s published data for Gottingen 398 aerofoil Table 1 shown above is the force report generated by fluent software for Gottingen 398 airfoil at 2 degrees AOA. Force vector (1,0,0) corresponds to the drag force experienced by the airfoil where as the vector (0,1,0) depicts the value of lift. WebCharacteristics of Clark Y airfoil, infinite aspect ratio. Example. From Fig. 18, the lift and drag coefficients for the Gottingen 398 airfoil for an aspect ratio of 6, at an angle of attack of 2°, is Cl = 0.293 and Cd = 0.031. Find corresponding …

WebJan 26, 2024 · It is also, together with a few other airfoils like the Göttingen 398 and 449, the basis of the thickness distribution of the NACA four digit range. However, airfoils designed with a desired pressure distribution in mind (as opposed to the pure geometry) will yield better results. Maybe you should look into Eppler or Quabeck airfoils instead ...

To do this, two main concerns had to be addressed: torsional divergence and bending behavior. For the cross section, the main concern was to create a torsionally stiff design, while the rest of the structure was geared toward minimizing bending. For swept forward wings, these behaviors are coupled; thus ... optimum barrel length for 5.56 nato
