Abstract

The influence of the amplitude of oscillations and initial velocity of a model on the error of determination of the aerodynamic damping moment has been studied by a method based on solving the inverse ballistic problem. Confidence intervals of the damping moment determined for various model parameters and the variance of linear coordinates are compared using the algorithm of identification of the aerodynamic characteristics of objects. An approach to estimation of the accuracy of obtained information during the planning of ballistic investigations is demonstrated.
