Because of their application, you will likely have difficulty finding study results of vortex generators used on that blended airfoil.

The usual spruce spars are replaced with off-the-shelf carbon fiber strips, but the construction Using a bi-objective genetic algorithm, the airfoil designs created by DbM are optimized to maximize both the lift-over-drag ratio, CLDmax, and stall angle tolerance, Δα, which results in a Pareto-front of innovative airfoils that exhibit substantial improvements in both objectives.
