Claims (4)

1. A method of protecting a moving object of ground-based military equipment, for example, a tank, which consists in detecting the direction of the threat and setting an interfering aerosol formation in this direction by throwing a grenade from the launcher from the protected object equipped with an aerosol-forming composition with its subsequent initiation and dispersal, characterized in that the angular protection zone is preliminarily divided in the azimuthal plane into sectors adjacent to each other, within each of which they are installed on the launch facility At the initial (combat) state, the installations with the total number of them in the sector corresponding to the number of defense cycles orient the installations along one of the sector boundaries, and when a threat is detected, the azimuthal position of the threat line is determined, the components of the wind speeds V v _{, np} and object V movement are measured _{c, pp} , perpendicular lines of threat, and adjust the angular position of the place of jamming relative to the line of threat by an amount characterized by the dependence Δψ = arctan S / L, in which L is the jamming range, S is the linear value of the correction of the position of the interference, determined by the expression

where t _gr is the average flight time of a grenade; b is the largest size of the silhouette of the object; B is the average width of the curtain equal to (3 ... 5) b; V _{in, st} - the standardized value of the transverse component of the wind speed, at which the lifetime of the interference and its effectiveness does not exceed the required condition V _{in, st} = 5 ... 6 m / s; determine the protected sector, inside which the place of jamming is located, select a charged installation, deploy it in the direction of the threat with simultaneous determination of the vector of the resultant grenade throwing speed and the linear velocity of the installation V _{p, l} on the cut of its trunk, defined by the expression V _pu , l = _{εt st} I, where ε is the angular acceleration of rotation of the barrel; t _barrel - the time from the start of the rotation of the barrel to the moment of the shot; I - barrel length; and at the moment of coincidence of the direction of the aforementioned vector with the place of jamming, a grenade is thrown. 2. The protection complex of a moving object of ground-based military equipment, such as a tank, containing launchers installed on the object’s tower and charged with grenades equipped with an aerosol-forming composition, a threat detector that determines the angular position of the threat source in the azimuthal plane in the coordinate system associated with the tower, an angular sensor the position of the tower relative to the longitudinal axis of the object, the sensors of the components of the wind speeds and the movement of the object and a computing device connected to an electric igniter a grenade and a threat detector, characterized in that each of the launchers is equipped with a rotary and control device that rotates the installation barrel in the direction of the threat and determines the current angular position of the barrel when it is rotated, while the tower’s angular position sensor, sensors of components of wind speeds and object movement and the control device of each of the installations are connected with a computing device, additionally equipped with a unit for calculating the resultant linear velocity vectors Installation on a section of its trunk and throwing grenades speed. 3. The complex according to claim 2, characterized in that the launcher rotary device is made up of a base rigidly connected to the object, a turntable with a barrel mounted on it, equipped with an axis with a gear sector, a torsion spring fastened on one side to the axis, and on the other, with the base, while the installation plane of the platform forms an angle with the axis equal to the angle of elevation of the trunk. 4. The complex according to claim 2, characterized in that the launcher control device is made up of an electromagnet with a retractor arm, traction, levers and a barrel angle sensor made in the form of a microswitch triggered by the action of the teeth of the sector associated with the axis of the turntable .
