TUNED MASS DAMPERS FOR ATR AIRCRAFT

Leonardo needed a solution to improve the passenger’s comfort  for ATR aircraft. SMAC suggested to use Tuned Mass Dampers (TMD)

OUR SOLUTION : TUNED MASS DAMPERS

We manufacture and test our Tuned Mass Dampers with a relatively low scrap in our laboratory into a specific control set-up including temperature controlled electrodynamic shaker.

 

More than several thousands of hundred TMD have been successfully delivered to Leonardo and flight proven since 2009.

CUSTOMER’S NEED

Leonardo needed a solution to improve the passenger’s comfort  for ATR aircraft. SMAC suggested to use Tuned Mass Dampers. TMD is an equipment consisting of a mass, a spring and a damper attached to a structure. The aim is to reduce the dynamic response of the structure. 

One of the specificities for this solution is the fine tuning of the resonant frequency with a 100% dynamic test and a less than 1% dynamic variation.
