Description
Technical Field
The invention belongs to the technical field of warheads, relates to a combined warhead, and particularly relates to a connecting device for the combined warhead.
Background
Blasting warheads is the simplest of the blasting warheads. It consists of a large number of high explosive charges in a metal shell, and the target is destroyed by the blasting effect generated when the main charge is exploded.
The state of application vast et al reports in the literature "the present situation and development of the warship warhead of conventional anti-ship missiles" (proceedings of war institute of war, sichuan university, 2006, page 14, 3): the damage power of the warhead is in proportion to the mass and the volume of the warhead, and the current warhead takes implosion type and great power as main research directions. However, with the increase of the size of the warhead, new problems are encountered, such as the increase of the processing difficulty of the shell, the increase of the charging difficulty, the increase of the transportation difficulty and the like.
The size of the warhead is affected by the above factors, and is difficult to increase after reaching a certain size. To meet the development requirements of larger-sized warheads, two warheads are typically connected in series prior to use. Before the experiment, one warhead is placed at the upper end of the other warhead, 2 warheads are superposed to form 1 warhead, the combined warheads are made, and then the warheads are detonated simultaneously to generate the explosion effect of the warheads with large explosive loads. However, the combined warhead has the following problems in the use process:
(1) the upper end warhead is placed on the terminal surface of lower end warhead, often no longer carries out mechanical connection, when the test field is windy or the terminal surface unevenness, in case the slope takes place, the easy landing of upper end warhead will take place dangerously.
(2) Because the size of the upper-end warhead is larger, when the upper-end warhead is placed towards the lower end face, a crane is usually used for moving in a matched mode, the stroke error of the crane is larger, after the upper-end warhead is placed, the coaxiality precision of the upper-end warhead and the axis of the lower-end warhead is poorer, the coaxiality error is larger, the axial symmetry is poor, and the power of the warhead after explosion is influenced.
(3) After the upper-end warhead is placed, the annular angle position precision of the upper-end warhead and the lower-end warhead is poor, and the annular angle error is large, so that the functional performance of the warhead is influenced, and the power of the warhead after explosion is influenced.
(4) Because the upper end of the warhead is heavy, when the upper end of the warhead moves through a crane, the moving distance is large each time, the position precision of each adjustment is poor, the adjustment needs to be repeated, the installation speed is slow, and the time is wasted.
