Abstract: The invention discloses a unidirectional spray type fire extinguishing bomb without high explosive fragmentation, includes a housing, a fuse, an igniter, an fire extinguishing agent and a main charge, and further includes a tail braking device, combustor, a plate closure, a piston and a diffuser. The housing, the tail braking device and the piston are made of light metal materials; the housing is cylindrical; the tail braking device is arranged at the bottom of the housing and is fixed with the housing through a screw nail; and the fuse is arranged on the diffuser and is fixed through a screw nail. During working process, when the fuse detects the fire extinguishing bomb to be 5-10 meters far away from a combustion source, the igniter ignites the main charge, the piston is pushed under high pressure to move in the housing, and the fire extinguishing agent is sprayed out from spraying holes to the combustion source for fire extinguishing.

Abstract: A combustion gas piston type movable guiding tube netting device includes a capture net (8), a traction head (6), a guiding tube (7), an igniter (3), a main gunpowder (5), a combustion gas generator (1) and a piston (2). The piston and the main gunpowder are placed in the combustion gas generator. The top of the piston contacts a triangular lug on the base of the guiding tube. The traction head is placed in the guiding tube, and another end of the traction head is tied on one corner of the capture net. When operating, the main gunpowder is ignited by the igniter, the resulting combustion gas pushes the piston to move, the piston pushes the guiding tube to move, and the combustion gas comes into the guiding tube and pushes the traction head to burst out the guiding tube, and the traction head drives the capture net to open. The combustion gas piston type movable guiding tube netting device has a quick expansion speed, and the area of the expansive capture net is big.

Abstract: A pollution-free liquid balancing device comprises a sealing bag (1), a front cover (2), a rear cover (3) and liquid balancing matter (4), wherein the sealing bag (1), the front cover (2) and the rear cover (3) are all plastic material. The sealing bag (1) is filled with the liquid balancing matter (4) inside, and plastically sealed under high temperature at both ends. The diameters of the front cover (2) and the rear cover (3) are matched with the inner diameter of a launch barrel (5), and the sealing bag (1) is provided between the front cover (2) and the rear cover (3). In an ordinary transportation state, the liquid balancing matter (4) is well sealed in the sealing bag (1), and a missile is launched forward by the propulsion of powder during launch, the sealing bag (1), the front cover (2) and the rear cover (3) crack instantaneously, and the liquid balancing matter (4) is ejected backward outside the barrel at high speed.

Abstract: Systems and methods allow for intercepting a small, low-altitude and low-velocity target. A system includes a detecting apparatus, a directing control apparatus, an aiming control apparatus, a launch control apparatus, a launching device, and an intercepting device. A method includes: searching and tracking a target by the detecting apparatus in a networking mode, or by the aiming control apparatus in a single-soldier mode; sending target information to the launch control apparatus; performing a trajectory calculation by the launch control apparatus; and launching the intercepting device by the launching device to intercept the target. A low-cost system with a short response time can thus be realized. The target falls with the net at a low velocity under a parachute, and this is desirable in a city environment.
