So, just having found this thread today, is there a summary choice for the highest lift and lowest drag airfoil for ultralight aircraft?
What is optimization of wing lift and drag distribution?
Do you believe airfoil selection has a hand in the drag?
Do you believe drag should be zero? That would be fairly optimum.
Should airplanes fly at slow speeds for safe take off and landing, or takeoff, cruise, and land at the same speed?
Are runways required? What length? No runways seem to be optimum.
As always, there are many ways that compromise leads to function.
For an ultralight, we (in the U.S.A.) have parameters and limitations...
Must weigh less than 254 pounds with fuel and engine
Carry only 1 person (not counting training designs for training purposes only)
Power-Off stall of 24 mph or less
Max Air Speed 54 knots indicated
I didn't think it was that difficult a question, but, rather, a simple request for information based on the stated purpose of this thread, to gather information on airfoils. Not sure why the contrariness seems so abundant. Nevertheless, I shall proceed with my own ideas and heed the sage advice that I do find freely given, to the best of my ability. Eventually, the results will speak for themselves.
