Flutter analysis of the IAR 99 SOIM aircraft

Abstract

Flutter analysis is considered for the minimum altitude at which the minimum designed Mach number is achieved, for the maximum altitude at which the maximum designed dynamic pressure is obtained and for the minimum altitude at which transonic effects begin occurring. Moreover, analyzes is performed for any other altitudes considered necessary. Flutter analysis results is graphically presented in equivalent speed with the curves of structural damping coefficient g required for flutter according to the flutter speed. Flutter analysis aims to determine the speeds of IAR 99 SOIM.
