FIELD: weapons and ammunition.SUBSTANCE: group of inventions relates to shells guidance systems. Method of firing with shells controlled by a laser beam includes measurement of the range to the target and introduction of the measured value Din a ground-based control system, comparison of the measured range to the target Dwith stored in memory of the ground control system range value D, allowing introduction of beam axis excess relative to target sighting line, setting of the excess under the condition D>D, launching of a guided shell, flight of the shell in the beam with an excess above the target sighting line until the moment of time set in the ground-based control system in accordance with the measured range to target, and alignment of the beam axis with the target sighting line. At that, when distance to the target is less than distance D, but more than distance D, where Dis the range to the shell at time momentωis a cutoff frequency of the system of shell control, rad/s, the centre of information field of the beam during the time from shell launch to time moment t, whereare displaced upward relative to the axis of the beam by the value Y= (0.2…0.5) R, where Ris the radius of the beam, after which they are matched during the time interval from moment of tto moment t, while, when the distance to the target is less than distance Dfiring is performed without any displacement of the centre of information field of the beam. Proposed device is equipped with electronic displacement generator whose input is connected to the output of the generator of time intervals, and output is connected to the first input of the adder.EFFECT: technical result consists in ensuring a possibility to exclude a contact of the shell with the underlying surface.2 cl, 4 dwg |
