The article considers the analysis of motion modes of an amphibious vehicle with aerodynamic cross-country terrain propelling screw when the gyroscopic moment influences on the bearing element of the construction, arising due to changes of the propeller disk plane which is a gyroscope with large rotational pulses. We obtained the computation expression for identifying the numerical values of the gyroscopic moment and the law of its change upon any turn in the direction of motion of the vehicle in any plane of reference (movement over bumps, bends and etc.). It was proposed to use the resulting computation expression to identify the most adverse driving modes, leading to the emergence of the largest gyroscopic moments.
