Conclusions
-
1.
The precise theory of restrictive torque enables us to realise the possiblity in principal of computing the maximum tangential stresses around the contour of the root section of the blade, which is very important in the case of stationary deformation.
-
2.
Both theories of restrictive torque proved to be practically equivalent in dynamic studies, in particular for calculating oscillations.
