[Study of human orientation with respect to vertical under effect of lateral and combined longitudinal-lateral accelerations].
Six test subjects were subjected to NZ and Ny/Nz accelerations in centrifuge cabin having rotation radius of 6.55 m. During rotation, test subjects have determined the position of the subjective visual vertical. The performed studies have demonstrated that during exposure to NZ and Ny/NZ accelerations the image of subjective vertical the direction of which with rise of lateral component approaches the direction of the vector of resultant acceleration. The expressivity of this effect decreases with an increase of the longitudinal component of acceleration. It was suggested that pulling of high lateral accelerations (up to 2-3 units of g) in the flight of advanced highly manoeuvrable aircrafts can hinder in-flight spatial orientation of a pilot due to appearing of the stable illusions of spatial position.
