Description

The invention relates to the means of destruction of marine objects.

Naval landings pose a certain threat to states with access to the sea, therefore, the intended landing sites during the threatened period are usually mined. However, the subsequent demining of these areas requires a lot of time, effort and money. The landing site can be mined immediately before landing, for which anti-amphibious mines are used, delivered to the landing area by rocket. They are capable of hitting the landing forces and means of the enemy and psychologically influencing him.

The prototype of the invention is a reactive bottom antiamphibious mine having an explosive charge, a proximity fuse, an ignition device, a power source and mine devices. It is located in the head of the missile and is fired at the amphibious landing area. The mine has a parachute and a mechanism for separating the missile part; after splashing down, it sinks to the bottom and is transferred to a combat state. When exposed to its proximity fuse by an amphibious craft passing over it, the mine explodes and hits it [1], [2].

The disadvantage of a reactive bottom antiamphibious mine is its insufficient effectiveness, due to the inhomogeneous bottom topography in the enemy landing area and the possibility of being detonated at a distance from the floating craft, which does not ensure its destruction. The mine can get into a deep place and not react to the landing craft.

The technical task and purpose of the invention is the development of an antiamphibious bottom mine delivered to the landing area by a rocket and ensuring its high efficiency in a wide range of depths and distances from the coast.

The aims and objectives of the invention are achieved due to the fact that an antiamphibious bottom reactive mine is proposed, including an explosive charge with contact and non-contact fuses, having a jet engine with a stabilizer and a device for separating it, a braking parachute and a current source, characterized in that the stabilizer is equipped with a mechanism for laying it out blades, the mine has a detachable aerodynamic cone, a clockwork, an electronic control unit, a target detection system with acoustic hydrophones and optical sensors, an underwater jet engine, lattice stabilizer rudders with a mechanism for their layout and rotation, a self-destruction device.

The jet engine (5) is used to deliver antiamphibious bottom jet mines (2) through the air to the aiming point (26) (figure 5). To stabilize the rocket in the air phase of the flight are the blades (6) of the stabilizer (figure 1), unfolding after the release of the mines from the launcher (23) (figure 5) using the device for their layout (18) (figure 2). At a predetermined point of the trajectory (25) (figure 5) at the command of the electronic control unit (15) the separation device (9) of the jet engine (5) is activated. Under the action of the oncoming air flow, the drag parachute (10) is extended and deployed, providing the necessary braking and stabilization of the mine (2) before it splashes down at the point (26). After splashdown, the compartment (4) with the parachute (10) is separated by the device for its fastening and uncoupling (12), the mine (2) sinks to the bottom and enters the ground with its aerodynamic cone (1). After the mine hits the ground (27), the mechanisms for deploying and turning (22) the lattice stabilizer rudders (21) are triggered, and the mine (2) is fixed at the bottom in a position close to vertical (figure 5).

The mine is transferred to the combat state by the expiration of the time set before launching into its clockwork (3), or by a program acoustic signal, for example, from an explosive sound source (cipher charge). This turns on its electronic control unit (15) and acoustic hydrophones and optical sensors (19) of the target detection system (13), forming a target detection zone (28) (Fig.6). The operation of the target detection system (13) and the electronic control unit (15) is provided by the current source (16) (figure 3).

Upon detection (30) of a target (29) (Fig.7) by an acoustic hydrophone and an optical sensor (19), mine (2) at the command of the electronic control unit (15) starts an underwater jet engine with a charge of solid fuel (8) and moves towards the detected targets along the trajectory (32), correcting the direction with lattice stabilizer rudders (21). When approaching the target (29) at the range of the non-contact fuse or when hitting its body, the explosive charge (14) of the mine is detonated (33) and the target is hit.

When the hydrophones of the mine receive a known acoustic signal from an explosive source of sound or a cipher charge, the electronic control unit detonates the mine for its self-destruction or simultaneously detonates the exposed mines in order to create a total damaging effect and psychological suppression of the enemy.

The mine self-destruction device serves to sink it and transfer it to a safe state without detonating the charge of the mine.

The technical result of the invention is an antiamphibious bottom reactive mine delivered by a rocket to the enemy landing area in advance or directly during the landing and serving to destroy the forces and means of the landing troops. Exposed mines detect enemy landing craft and floating equipment moving in the water, attack them with the help of an underwater jet engine. The devices of the mine provide guidance of the mine on the detected target and its destruction, simultaneous detonation of the exposed mines in order to create a total damaging effect and psychological suppression of the enemy, as well as sinking the mine and transferring it to a safe state without detonating the charge.
