The paper is devoted to development of a new method for aeroelasticity analysis with taking into account gyroscopic forces. The developed mathematical model is applicable for computation of dynamic aeroelasticity characteristics (eigenfrequencies and vibration forms, flutter, dynamic response in the frequency and time domain) in dependents on angular momentum of rotating rotor including case of elastic attachment of an engine on a pylon under the wing. The example of destabilizing influence of gyroscopic forces on flutter and aeroservoelasticity characteristics of an airplane with engines on pylons under the wing is described and analyzed.
