Charakterystyki aerodynamiczne łuski naboju działka lotniczego w opływie przestrzennym

Jerzy Maryniak, Mirosław Nowakowski

The results of analysis of basic aerodynamical characteristics of an aviation shell model have been presented in the paper. The results have been obtained from the wind tunnel tests for the attack angles ranging from 0 to pi. By the use of the measurement results some relations for aerodynamical coefficients have been determined i.e. for drag coefficient, lift coefficient, pitching-moment coefficient as the function of attack angfe. The pitching-moment coefficient was approximated by algebraic polynomials.
