I'm trying to find out what type of effect there will be on the Max endurance of a turbo prop aircraft if fowler flaps are extended? I know from experience in a L-13 glider that sink rate can be decreased thus increasing the glide endurance but I'm not sure if this at all translates to a prop aircraft. I've read that the desired effect is to minimize the power required, and that is dependent on the total drag (i.e. thrust required) times the velocity. I've also read that by lowing the flaps you are reducing the induced drag and increase the parasitic drag resulting in the total drag curve moving up and to the left. I know that fowler flaps provide the greatest increase in lift for the increase in drag. The inherent question is, is it possible to move the curve enough to the left and not up too much that the result is a net decrease in power required?????
Please help me out and correct me on what I may have wrong (which I'm sure is something.)
