Abstract
In order to clarify the results of experimental studies with free-spinning aircraft models in a vertical wind tunnel, the analysis of the force pitching moment coefficients acting on the model, full-scale aircraft and their elements was carried out. It is shown that some differences in these coefficients are acceptable, which is confirmed by a satisfactory convergence of the results of model studies and full-scale aircraft flight tests.
