ICR presented the “Identification of subsystems in a tilt-rotor” in ISMA 2022. The congress took place in Leuven, Belgium from 12th to 14th September. In the framework of PIANO, ICR is performing the vibro-acoustic characterization of a tilt-rotor through the ATPA technology. To do so, a subdivision in subsystems is required. The work presented in …

TFNG with DSL work together on the Active Noise Control topic during the PIANO project. TFNG manages all the ANC activities in the project and will integrate the ANC prototypes inside the cabin of the tiltrotor aircraft. DSL will develop and test new ANC algorithm that will be used in the TFNG ANC controller. Interior …

Last July the first experimental campaign of PIANO was performed by ICR vibroacoustic R&D team. It took place at the Leonardo Helicopter Division (LHD) facilities, in Cascina Costa, Italy. An Advanced Transfer Path Analysis (ATPA) test was conducted in a tiltrotor aircraft prototype developed by LHD. A static ATPA analysis was undertaken in the passenger …
