Abstract

Due to the need of higher efficiency and the reduction of CO2 and noise emission the bypass ratio of gas turbines tends to increase. This leads to higher rotational masses which arises the question of gyroscopic moments influencing the eigenbehavior of the aircraft and thus the system stability regarding structural depended phenomena, e.g. flutter. Therefore this paper presents a multibody model to determine the structural coupling between a Coanda wing and an ultra high bypass ratio gas turbine (BPR of 17). The results in form of the spectral analysis of an eigenvalue analysis enables the understanding of the coupling mechanisms and gyroscopic influences. By analyzing the time dependent behavior of the wing-engine system under consid- eration of a follower force, representing the thrust, deepens the understanding of the structural load at the wing root.
