Abstract
The analysis of a technique of measurement of dynamic angular derivatives , and also complexes of rotary and non-stationary derivatives, prepared to their subsequent division, in conditions of required corners of attack and slidings is carried spent. It is established, that measurement at is incorrect, and calculations of a derivative and complexes, are made under erroneous formulas. New formulas for definition are given. Oscillatory experiments are offered at positions of an axis of the fluctuations which are taking place through axes OZ and OY models. As a result of realization of these experiments (together with the experiments connected to fluctuations around of axis OX) unshared complexes may be measured directly without computing operations of reduction of axes.Download
