The paper considers vibration paths properties of gas turbine engine non-rotating parts aimed for application for vibration diagnostics, specifically in Vibropass-port™ as the methodical and algorithmic platform for practical application. Au-thors discuss reasons for transfer features research and application in vibration diagnostics. Some specialties of transfer features are considered for different types of excitation sources, like a whole rotor or separate gear. Low frequency range and wide frequency band vibrations generated by such sources need differ-ent approach to experimental testing techniques. The general view is given on ex-perimental techniques for testing of integral aggregates and smaller excitation sources of an engine. There is analysis of transfer features of concentrated and distributed multiple sources as well as some samples of experimental testing and transfer coefficients determination. Main areas of transfer properties in applica-tion of engine vibration diagnostics are considered. The paper includes conclu-sions regarding discussed matters and tasks for further works.
