In the present paper, an attempt has been made to calculate the flutter reliability of a swept back plate taking uncertainties in material and aero properties into consideration. As flutter analysis for computing flutter speed involves finite element analysis followed by an extensive interpolation process, a regular Monte Carlo Simulation (MCS) is infeasible. Hence, in the present work, a novel approach involving Response Surface Method (RSM) of simulation followed by MCS has been used for the study. The variation in flutter speeds due to uncertainties in the material properties such as Young’s modulus and mass density and aero parameters such as air density and Mach number are studied and the reliability has been computed for different failure conditions.
