In this paper, the problem of modeling and analyzing of emergency movements of a quadrocopter as a body with six degrees of freedom is considered. The mathematical model of motion is a non-linear system of differential equations with four control channels. Using MATLAB, a numerical simulation of the flight process of the vehicle was carried out in two emergencies: 1) with partial failure of one engine in horizontal flight; 2) with complete failure of one engine while reducing the vehicle. The graphs of emergency movement of the apparatus are given for a given law of variation of the angular velocities of rotation of the screws. It is shown that the loss of thrust on at least one quadrocopter screw leads to a significant change in its position. The simulation results provide a basis for further search for the class of movements for which the apparatus can be saved.
