PURPOSE: A method for directly calculating a velocity of standard atmosphere flutter is provided to perform a polynomial matrix calculation for structure with small time and effort, and to obtain a stable calculation result. CONSTITUTION: A structure characteristic, an air force and an atmosphere characteristic at a matched point are inputted(S1). A velocity-gravity curve diagram at the matched point is written by using the inputted values(S2). The flutter velocity is calculated from a velocity-gravity curve(S3). A result is outputted by deciding the calculated flutter velocity and a frequency(S4). |
