Problems solved by technology

At the same time, the metal fuel in the formula has always been wrapped by these polymer materials. Before the metal fuel is ignited, the surface polymer material needs to be destroyed or ignited before it can burn. However, the explosion process of explosives is only a few hundred milliseconds, and it is difficult to complete the above chemical reactions. Therefore, the entire system Low fuel combustion efficiency and low energy utilization
[0007] To sum up, there are three main problems in current research in this field: (1) The fuel density and calorific value of the liquid-type cloud explosives are small, and the power of the cloud explosives cannot be further improved; (2) The liquid-solid cloud explosives Components contained in explosives, which will affect the use and safe storage of ammunition due to their own (sedimentation) reasons
(3) Polymer bonding solid cloud explosive agent, due to the effect of high molecular polymer, the utilization rate of fuel is low

Embodiment 1

[0042] Table 1 shows the performance comparison of fuel air explosive formulations MN-1 and MN-2 with different hydrocarbon fuels and primary detonation basic formulation 1.

[0043] Table 1 formula composition (weight %) and performance

[0044]

[0045]It can be seen from Table 1 that the density, heat of combustion, detonation volume and power of the fuel air explosive formulations MN-1 and MN-2 containing pentacyclodecane and diamantane are significantly higher than those of the basic formulation 1. Among them, the density of MN-2 formula has been increased by 3%, the heat of combustion has been increased by 25%, the heat of combustion by volume has been increased by 29%, and the power has been increased by 23%. The detonation capacity has been increased by 43%, and the volume of gas formed by unit mass explosive is 1.43 times that of the basic formula, which can significantly expand the coverage area of ​​the detonation cloud area and enhance the lethality of the fuel....

Embodiment 2

[0047] Table 2 shows the performance comparison of fuel air explosive formulations MN-3 and MN-4 with different hydrocarbon fuels and primary detonation basic formulation 2.

[0048] Table 2 formula composition (weight %) and performance

[0049]

[0050] As can be seen from Table 2, the density, heat of combustion and power of the fuel air explosive formulations MN-3 and MN-4 containing pentacyclodecane and cubane are all higher than those of the basic formulation 2. For hydrocarbon fuels, compared with the polymer binder HTPB, the energetic particles in fuel air explosives are easier to be ignited, so the energy release efficiency is higher.

Embodiment 3

[0052] Table 3 shows the performance comparison of fuel air explosive formulations MN-5 and MN-6 with different hydrocarbon fuels and primary detonation basic formulation 3.

[0054]

[0055]

[0056] It can be seen from Table 3 that the density, heat of combustion, detonation capacity and power of the fuel air explosive formulations MN-5 and MN-6 containing pentacycloundecane and diamantane are significantly higher than those of the basic formulation 3.

Abstract

The invention relates to a solid cloud detonation explosive, which consists of the following components by weight: 5%-15% of solid hydrocarbon fuel; 25%-65% of metal fuel; 5%-50% of a sensitizer; and10%-30% of ammonium perchlorate. The invention overcomes the problem of low energy density in solid cloud detonation explosives in the prior art, and a novel tensile ring-containing solid hydrocarboncompound characterized by easy volatilization and high density and calorific value is added to substitute isopropyl nitrate, epoxy and high polymer fuels with low combustion calorific value, thus realizing stronger power of the cloud detonation agent. Under the circumstance of a limited warhead volume, the solid cloud detonation explosive provided by the invention can effectively increase the carried energy, realize miniaturization of missiles, and improve the maneuverability and penetration capability. Compared with the previously used fuels, the volume of cloud mist formed by unit mass of the cloud detonation explosive adopting the high-density hydrocarbon compound is larger, the coverage area of the cloud mist area can be significantly expanded, and enhance the lethality of the warheadcan be strengthened.

Description

technical field [0001] The invention relates to a fuel air explosive, which belongs to the field of propellant formula development and relates to a solid cloud explosive. Background technique [0002] Cloud bombs are divided into secondary detonation type and primary detonation type according to their detonation forms. The main charge of secondary cloud bombs is fuel air explosive (Fuel Air Explosive, FAE for short), which is a high-energy fuel mixture. When the warhead is dropped at a certain height, the throwing device throws the fuel in the projectile into the air, and the fuel quickly diffuses into mist-like fine particles and fully mixes with the surrounding air to form an aerosol-like cloud, which is then detonated for the second time to cause damage , the explosion can produce high temperature and high pressure of 2500 ℃, and its destructive power is 5 to 10 times that of ordinary explosives of the same quality. It mainly uses detonation and combustion effects to dep...
