Abstract
This paper is dedicated to active damping of gas turbine engine blades forced vibrations using the capabilities of piezoelements. Experimental investigations are carried out with a non-rotating compressor blade, rigidly clamped on a shaker. Vibration damping was carried out by using of feedback based on a piezoelement pair fixed on the blade surface and used as a sensor and an actuator. A significant decrease of resonant stresses in the blade is shown.
