I'm curious in knowing why a T-tail is used on most powered sailplanes, with a propulsion arrangement similar to the picture attached. In the example provided, the horizontal tail (HT) lies straight in the wake of the propeller, hence in disturbed airflow which will increase drag.
My first thought is that it could be for spin recovery. That is, to prevent the wake from the HT from "blanketing" the rudder in the event of a spin. Aren't there other ways of doing this that will result in a lower drag penalty?
What other reasons could it be for? Would like to get a much better technical insight.
