not always available. The article looks at the identification
technique of the structures dissipative properties according
to the results of modal testing by the phase resonance me-
thod. The full-scale dynamic system is described by the
mathematical model with the finite number of degrees of
freedom. In order to identify the damping forces properties,
the ratios between forced monophasic vibrations and struc-
tural eigenmodes are used. As an example, a mathematical
model of a dynamically similar model of the aircraft is con-
structed, which describes a number of the structure
eigenmodes. A good agreement of the design and experi-
mental amplitude-frequency characteristics of the object is
observed. The full-scale aircraft test results, permitting to
identify the aircraft dissipative properties are shown
