I love the idea of it, but how are you sure that the angle of the trimming tail is optimal for every angle? I get that it will move to something possibly close to optimal, but what is optimal should take into account the lift performance of the particular tail and the force needed to move the wing. Am I missing something here?
The force needed to move the wing is very small because the wing pivots on its centre of effort - this is what you see on planes that have all-moving tail (stabiliser). However some degree of fine tuning is possible by altering the position of the "Throttle" lever. see my page www.windthrusters.com/story.html
They work amazingly well....i played with one years back on a 14ft sailing dingy, even thought it was not as big as i initially wanted to build, it drove the dingy as well as the conventional sail almost 3 times the sq/ft of the wing.......When i get the chance i intend to build another wingsail with a few tweaks i think worth trying out
Thank you Peter for all the work. We need people like you.
