The drag-divergence Mach number is predicted to be greater than 0. Airfoils can also be plotted manually using the coordinate dimensions to draw points on the airfoil and drawing the curve of the airfoil using a French curve or flexible rule. Increasing amount of universities and research organizations worldwide choose Penguin B as a standard UAV airframe for their projects. With its predictable and gentle stall characteristics and flat bottom outline, the Clark Y airfoil is an ideal choice for sport RC model aircraft. The same is true for keels, rudders and hydrofoils. These component modifications included changing the airfoil, planform, aspect ratio, and adding a winglet. By the way, the airfoil they list is incorrect, the sample I have seen has a 15% thick airfoil, probably the Naca 4415, not the 4412 they have listed. The Near Space Unmanned Aerial Vehicle Team (NSUAV) at University of Colorado at Colorado Springs (UCCS) designed and constructed an Unmanned Aerial Vehicle (UAV).
