Inverting amplifier; aero-elasticity
In experimental stand for measurement of aero-elasticity is each blade excited by two mechanisms with an A.C. input. When both driving signals are in phase, the swinging of blade is parallel. When one of driving signal is in opposit...

Non-smooth modelling of a periodic structure with contact-friction and aero-elastic couplings
The paper presents a generalized model of a periodic structure (bladed disk) which contains contact-friction and aero-elastic couplings. Such structures are usually employed in e.g. steam turbine bladed disk to suppress blade vibrat...

Dynamic phenomena of a blade system with aero-elastic coupling
The paper presents an approach to bladed disk with aero-elastic coupling modelling. The bladed disk is created by blades modelled as airfoil profiles, which are mutually interconnected by shrouding. The shrouding and its parameters ...
