Tiltrotor Acoustic Data Acquisition and Analysis

Abstract Pressure load measurements in operative conditions represent a fundamental parameter for improving the knowledge of in-flight forcing generation and transmission. Furthermore, it is step assessing validity confidence numerical methods able to predict such pressure loads, usually generated by propulsion turbulent boundary layer. The experimental analysis correlation with are activities required as starting point studying transmission mechanism through fuselage which responsible vibration noise level can be measured inside identifying potential solutions their mitigation. have been carried out on Leonardo Helicopter tiltrotor main goals perform validation an setup fully new environment assessment data procedure according objectives Clean Sky 2 Fast Rotorcraft Project T-WING (CS2, joint undertaking third amended bi-annual work plan budget, 2018–2019).
