IMPROVING THE GUIDANCE ACCURACY OF THE UNMANNED AERIAL VEHICLE
A.V. Lopuhov, A.I. Phedorov, V.R. Dragun

The constant increase in the flight performance of air attack means requires the attraction of new approaches to the method of creating control forces and moments for free aircraft, which is an urgent problem for their reliable interception. The classical aerodynamic methods of creating control forces and moments for the on-board stabilization system of an unmanned aerial vehicle are not capable of adequately solving the problem of defeating modern and promising air attack weapons. The solution to this problem is ensured by the use of a combined method for creating forces and moments, gas–dynamic is used. The use of an improved combined method of creating and moments allows the reaction time to be reduced by a factor of five over the entire height range, and the maximum control acceleration or overload can be doubled. The use of the proposed method for creating forces and moments for an unmanned aerial vehicle will ensure reliable inter-ception of high-speed and highly maneuverable air attack weapons.
Keywords: unmanned aerial vehicle, combined method, guidance, reaction time, micro-pulse motors, control acceleration, forces and moments.
