Abstract

Measuring aeroacoustic noise and its transmission into the passenger compartment of an aircraft provides a way to evaluate the vibrational energy caused by the turbulent boundary layer and other aeroacoustic sources, the transmission path and the sound radiation into the compartment. The measurement results are used to validate numerical models and to identify parameters for a turbulent boundary layer model. This was used in a flight test campaign at the DLR to separate different sources and determine their transmission into an aircraft. The measurement concept and results from the flight test will be presented, whereupon the potential in applying this concept to high-speed train measurements will be discussed.
