title = "Dynamic pressure perturbation method for flutter solution: The Mu-Omega method",
abstract = "Applying perturbation to dynamic pressure in the nominal aeroleastic equation of motion, a Mu-Omega method is presented for flutter solution. Utilizing structured singular value mu as stability margin indicator, the method simply uses frequency domain aerodynamics to solve nominal flutter and divergence margin through frequency domain mu analysis. The error of flutter reduced frequency is selected as convergence criterion during airspeed iteration. Detailed algorithm is given and three numerical examples are solved for demonstration. It is shown that the Mu-Omega method has good convergence and high accuracy, and the flutter and divergence result from the Mu-Omega method correlate well with that of the p-k or KE method.",
