This paper deals with a modelling and a sensitivity modal analysis of the moving blade packet. The blades are considered as ID continuum mutually coupled by a shrouding. The mathematical model makes possible to analyse an influence of centrifugal forces, gyroscopic effects, blade's elastic seating to bladed disk and material and geometrical parameters of the shrouding on moving blade packet modal properties.
