FIELD: military equipment.

SUBSTANCE: invention relates to military technology and can be used to build control systems for aerial bombs for various purposes. Method of controlling the planning bomb is based on measuring the speed of the flight of the bomb using pressure and temperature sensors installed in the nose of the bomb. According to the information from these sensors, according to the laid-down algorithm, the flight of the bomb is controlled using electric rudders. This control system is fully protected from exposure to EW funds. When an aircraft (AC) reaches the striking distance target area of an aerial bomb (AB) with the help of the on-board systems measure the mutual position of the coordinates of the aircraft and the target (range L and height H). With the help of onboard sensors in AC, the ground speed V and the wind speed are measured. This information (distance to the target L and the speed of the aircraft in the direction of the target V, as well as wind speed) is continuously introduced into the computers that are part of the aiming and navigation complex of aircraft and aircraft. Based on the known algorithms, the required deviation of the rudders of the AB is continuously calculated and signals proportional to the deviation of the rudders are fed to the AB actuators. Position of the AB rudders is controlled by feedback sensors connected to the AB rudders. Direction of the bombing is chosen basing on the speed and direction of the wind. At the time of uncoupling AB from AC, the power supply to the rudders from AC stops. After the separation of the AB from the AC, the power supply on the AB is started and the rudders are controlled against it. After starting the current source on AB board, the AB calculator is started. Using the speed sensor installed in the nose of the bomb, continuously determine the total pressure of the air flow in the direction of the bombs and calculate the speed of the aerial bomb v_i. Determine the static air pressure in the area of the aerial bomb P_i. For each flight time interval Δt, using the relation v_yi=Δh_i/Δt, determine the vertical component v_yi speeds of falling aerial bomb where Δh_i height at which the aerial bomb fell in time Δt, that, in return, is determined by the ratio Δh_i=h_i-h_i+1=l_n(P_i+1/P_i)R_cT_c/gM, where P_i – atmospheric pressure at height h_i, P_i+1 – atmospheric pressure at height h_i+1 (h_i>h_i+1), M is the molar mass of air, g is the acceleration of free fall, R_c – universal gas constant, T_c – average air temperature at altitudes h_i and h_i+1. Determine the horizontal component of the flight speed of the bombs v_xi using the ratio v_xi=(v_i²-v_yi²)^1/2. Calculate the distance ΔS_i, traveled by a aerial bomb to the target for a period of time Δt, using the ratio ΔS_i=v_xi Δt. Continuously from the calculator of the aerial bomb, control commands are provided to the electric actuators of the aerial bomb, that ensure the inclination of the aerial bomb, allowing you to select speeds v_yi and v_xi in such way that the fall of the aerial bomb into the target occurs at a distance of

where n=H/Δh.
