Abstract
The paper reports the research of the “engine-attachment-airframe” multi-connecting dynamic model by separation it into independent sub-systems according to the engine support (engine mounting points). New generation aircraft are switching to engines of high bypass ratio, which require dynamic characteristics of new structures to be refined. The studies we have performed allowed us to refine significantly dynamic models of aviation gas turbine engine and airframe within rotor frequencies range and to reveal tendency of changes of dynamic characteristics particularly those of engine bodies with increased bypass ratio
