the area inside the curve would give us the integral time scale, thus a fast changing curve, (like the one represented) would mean lost of memory and very little correlation, and slow changing curve would represent some correlation
Weighted sum of sine and cosine give the portion of spatial/ time that takes up in your recorded signal. But you have not mention how to determine this variables relating to internal force of blade. The turbulence and flutter contribute to the load that varies in respect of time.
Does the wavelength of each wave contributes to the turbulence scale or is it the amplitude of each wave that is contributing to turbulence scale calculations?
