ABSTRACT

This paper describes the development of a method for calculating dynamic aeroelasticity characteristics (eigenfrequencies, flutter, dynamic response, and aeroservoelasticity) by taking into account gyroscopic forces using the polynomial Ritz method. An example of the destabilizing influence of gyroscopic forces on the flutter and aeroservoelasticity characteristics of an airplane with engines located on pylons under the wing is presented.
