| Abstract: | A method is proposed for identifying the aerodynamic characteristics of a model the flow about which varies considerably in
the course of motion. In this method, the trajectory of the model is split into sections with different types of the flow
and then similar data from these sections are collected into groups and processed. The aerodynamic characteristics are identified
by the method of successive approximation using a differential correction algorithm. The accuracy of the results is analyzed. |
