In the INPHASE project, the cabin noise and vibration comfort of novel aircraft concepts are predicted in the preliminary design phase and made tangible in a virtual environment. Various concepts are assessed for their validity in use as passenger aircraft.
Motivation and background
The goal of climate-neutral aviation has led to a large number of new aircraft designs and propulsion concepts in the passenger aircraft sector. Whereas in the past the focus was on improving classic aircraft configurations, today the focus is on alternative propulsion technologies such as electric propulsion, hydrogen combustion and open-rotor engines.
The DLR project EXACT conducted economic and ecological assessments of such concepts for short-range flights. One aspect that is often neglected in these assessments is passenger comfort, particularly with regard to cabin noise and vibrations, which are heavily dependent on the aircraft design.
Subsequent measures to reduce noise can have a negative impact on profitability. Therefore, an early assessment of cabin noise in the design phase is essential. The challenge is to make precise acoustic predictions and to link the results in an interdisciplinary manner.
