Validation of a Motion Sickness Prediction Model via Flight Tests on DLR's Bo-105 Helicopter

Kurzfassung

In previous work, a motion sickness prediction model aimed at vertical lift applications was developed. To validate this model, flight tests with an MBB Bo-105 Helicopter owned and operated by the DLR were conducted. In total, 32 test subjects were flown in 16 sorties on 30 min sinusoidal flight paths of various frequencies. The test design and implementation included the development of a suitable measurement flight instrumentation, auditive cueing systems for accurate following of the test trajectory, and questionnaires for recording motion sickness during flight. The results are analyzed, and it is shown that the previously developed motion sickness prediction model agrees well with the motion sickness observed during flight in the case of medium motion sickness.
