The present application relates to the technical field of aerial bomb fuze, and discloses a novel aerial bomb fuze clockwork mechanism with rotation speed control, which comprises a gear train, a rotor prime mover body, a safety device, a lower check ring and a rotor, characterized in that the safety device is fixed on the shaft of the gear train by the lower check ring, the safety device is provided with gear teeth and is engaged with the output wheel in the gear train, and the safety device is driven to rotate by the output wheel; the constant speed governor is located between the gear train and the toothed disc, the toothed disc is fixed with the bushing through riveting and is fixed on the central shaft by the upper check ring; the other end of the anemometer shaft is connected with the rotor seat through screw threads, the rotor seat can rotate relative to the time mechanism shell and drives the anemometer to rotate; and the rotor is fixed on the rotor seat. The present application can improve the timing accuracy, prevent the safety from being released too early, better protect the safety of the airplane and the pilot, has certain overload resistance, and when the overload reaches 20G, all the internal parts can remain stable and will not be damaged.

The present application relates to the technical field of aerial bomb fuze, especially to a mechanical time aerial bomb fuze with universal ignition function. The aerial bomb fuze currently used has problems of large timing error, insufficient ignition reliability and safety. The present application designs an anemometer and an isokinetic speed regulator, and through the regulation and control of the two, effectively increases the timing accuracy and safety. Considering that the M904 fuze adopts an impact ignition mechanism, if the angle of the aerial bomb when landing is not within the range of impact ignition, normal ignition will not be achieved. To overcome this limitation, the present application adopts a universal inertia ignition mechanism, improving the ignition reliability.

The present application relates to a kind of aviation bomb bridge target ammunition demand calculation method of attack, belong to weapon combat effectiveness evaluation field.It includes when bomb enters target with 0 or 90 ° azimuth, bridge target can be regarded as a plane target, the effective length L ET And width W ET Of bomb damage area can be obtained;Bomb precision function g (x) and damage function c (x) are defined in horizontal, the expected value of single bomb under different bomb release error is obtained by integration, the damage probability of target in transverse direction;Bomb precision function g (y) and damage function c (y) are defined in longitudinal direction;Single aviation bomb damage probability to bridge attack is calculated by considering bomb reliability;Finally, the number of bomb reaching predetermined damage effect P D The present application solves the problem of efficiency evaluation of aviation bomb to bridge target in different entry directions.

The application discloses a ground-air integrated multifunctional fire extinguishing system and belongs to the technical field of fire-fighting equipment. The system comprises a ground vehicle combat unit, an aerial bomb-throwing unit and a high-rise building fixed water spraying unit. The ground vehicle is composed of an ice cannon launching vehicle and a water supply supply vehicle, the ice cannon vehicle adopts a six-legged walking mechanism and a multi-tube launching device, can launch high-density ice bombs or other fire extinguishing media, and is provided with an independent generator and a quick power supply interface, and the two vehicles are backup for each other; the aerial unmanned aerial vehicle or fixed-wing aircraft is hung with a throwable ice bomb cabin to realize high-altitude accurate attack; and the high-rise building is internally provided with a multi-section relay type independent water spraying system. The application effectively solves the fire extinguishing problems of complex fire scenes such as mountains, high-rise buildings and oil and chemical plants through ground-air three-dimensional cooperation, double effects of ice bomb cooling and suffocation, safe redundant power supply and all-terrain adaptability, and has the advantages of high fire extinguishing efficiency, strong reliability and wide application range.

The utility model relates to a hot start switch suitable for an airborne fire extinguishing aerial bomb, and belongs to the technical field of forest fire extinguishing. Firstly, the thermal bimetallic strip assembly is assembled in the annular groove of the warhead, then the live striking body and the thermal bimetallic strip assembly are assembled in place through a special tool, and the live striking body and the thermal bimetallic strip assembly are fixed through a connecting screw. The power connection positive electrode component is fixed to the first step hole of the live-action body through a connecting screw; the bullet head provided with the thermal bimetallic strip assembly, the live striking body and the power connection positive electrode component is fixedly connected with the bullet body through threads; and finally, after a positive electrode guide rod on the power connection positive electrode part penetrates through a small hole of the power connection negative electrode plate, the power connection negative electrode part is fixed to a second step hole in the bottom of the projectile body through a connecting screw. The hot start switch suitable for the airborne fire extinguishing bomb not only can realize the function of reliable closing of the switch, but also has the advantages of light weight, simple structure, good safety and high reliability.

The invention relates to the technical field of individual soldier protection equipment, in particular to an individual soldier protection umbrella with a radar-infrared-visible light stealth function for defending small bombs of an unmanned aerial vehicle and a preparation method of the individual soldier protection umbrella. The individual soldier protection umbrella comprises an umbrella handle, umbrella ribs, an umbrella cover, umbrella buckles and an umbrella disc, and the umbrella handle is connected with the umbrella ribs through the umbrella disc; the umbrella ribs and the umbrella cover are connected through umbrella buckles and local sewing, and the umbrella cover is in an opened or closed state by pushing and pulling the umbrella disc; the umbrella cover is composed of a plurality of flexible layers. The flexible layer sequentially comprises an outer skin flexible layer, a core material flexible layer and an inner skin flexible layer from outside to inside. According to the umbrella cover of the individual soldier protection umbrella, by means of the shear thickening liquid soaked in the core material flexible layer, the nano-particle network structure in the core material flexible layer rapidly gathers at an extremely high strain rate at the moment when the core material flexible layer is subjected to high-speed impact of bullets or fragments, so that the viscosity of the fluid is instantaneously increased, and the stability of the single soldier protection umbrella is improved. Therefore, the original soft core material layer is quickly converted into a local solid-like state in the hit area.
