Abstract
The Flying-V is an innovative aircraft design developed by Delft University of Technology. Its unique configuration positions passengers laterally farther away from the centre of rotation compared to conventional aircraft. In light of this unique structure, a passenger-in-the-simulator experiment was conducted using the SIMONA Research Simulator to examine to what extent the severity of motion sickness increases with greater lateral distance from the centre of rotation.
The experiment was conducted using the Time to Bank manoeuvre. Due to the rolling acceleration, as the lateral distance of the seating position from the centre of rotation increases, passengers experience a higher magnitude of heave motion in addition to the roll motion. The participants were exposed to three different lateral seating positions, including sitting at the centre of rotation, sitting laterally offset at 3.5 m, and sitting laterally offset at 7 m.
Motion sickness was predicted using the 6 Degrees of Freedom–Subjective Vertical Conflict model, which provides the Motion Sickness Incidence. According to the model’s prediction, an increase in the level of heave motion is expected to lead to a higher level of motion sickness severity for passengers. During the experiment, participants’ motion sickness severity was assessed using the MIsery SCale (MISC).
Although no statistically significant differences were observed among the conditions, sitting laterally offset at 7 m had a higher mean of the participants’ maximum MISC score of 3 than sitting laterally offset at 3.5 m, with a mean of 2.4. However, neither of these conditions showed higher scores than sitting at the centre of rotation, with a mean maximum MISC score of 3.6. Therefore, the results suggest that sitting laterally farther away from the centre of rotation in the Flying-V did not lead to increased motion sickness severity.
