Annotations languages:

The article is based on the mathematical model of occurrence of intensive oscillations of supersonic aircraft aerodynamic control surfaces analysis in transonic flight speeds proposed the mathematical model for predicting the level of fluctuations in experimental studies. The adequacy of this model is confirmed by comparing the experimental results with the results of calculations.
Keywords: mathematical model, oscillations, aerodynamic control surface, supersonic aircraft, M number
