Embodiment Construction

[0031] figure 1 Among them, the main body of the present invention is a cylinder 4 made of metal such as alloy steel, stainless steel, and low carbon steel, and an igniter sleeve 1 made of metals such as duralumin and super duralumin fixed at both ends of the cylinder 4 and a connecting end cap. 17 poses. The cylinder body 4 has an aspect ratio between 5 and 10, which can ensure the minimization of the volume of the whole bait after the bag coat is folded. Since the diameter of the mother bomb is fixed, to ensure that the bait can be smoothly loaded into it, its radial size must be strictly controlled. On the one hand, the smaller volume is convenient for loading the bomb, and on the other hand, it can prevent the capsule from being squeezed. Damage caused by force.

[0032] The two ends of the barrel 4 are processed with oppositely rotating threads, which are connected to the igniter sleeve and the connecting end cap through threaded connection. By setting the anti-rotating...

Abstract

The invention discloses a gas generator for bait. An igniter sleeve is arranged at the upper end of a cylinder, and an end cover is connected to the lower end of the cylinder. An inner cavity of the cylinder is divided into a one-level combustor, a two-level combustor and a three-level combustor. A filter screen is arranged in the lower portion in the cylinder. One or more exhaust ports are formed in the wall of the cylinder. The three-level combustor is internally provided with a first powder cup and a second powder cup. The first powder cup and the second powder cup contain cooling agents. The bottom of the first powder cup and the bottom of the second powder cup are provided with bottom holes. The upper portion of the first powder cup is provided with a buffer component. The two-level combustor is internally provided with a gas generating powder column and a gas generating powder tablet. The one-level combustor is internally provided with a powder cylinder, a buffer component, a second partition plate and an ignition powder tablet. Ignition powder particles are arranged in a center hole of the ignition powder tablet. The upper portion of the ignition powder tablet is provided with a first partition plate and an igniter. A pull pin at the upper end of the igniter extends out of the igniter sleeve. Air vent grooves are formed in the wall of the powder cylinder. Holes are formed in the bottom of the powder cylinder. An exhaust path is formed between the gas generating powder column and the inner wall of a cylinder body of the two-level combustor. The gas generator has the advantages that the ignition time is adjustable, the inner pressure and the radial size are small, the outlet temperature is low, the pressure is adjustable, pressure repetition is stable, the filtering effect is good, and the gas generator is overload resistant.

Description

technical field [0001] The invention relates to a high-altitude gas generator that provides airflow with a certain temperature to the capsule of a decoy bomb. After rockets, artillery shells and missiles are launched, the generator body can generate a heat source of infrared radiation and fill the airbag with hot gas. Background technique [0002] At present, there are two common types of gas generators used for airbag inflation: pie-shaped and cylindrical-shaped, and their structures are mainly assembled from an ignition system, a gas-generating agent, a filtration / cooling system, a metal shell, and a metal membrane. When an external electrical signal acts, the electric squib in the ignition system is excited and ignites the ignition powder. The high-temperature particles or high-temperature airflow generated by the ignition powder pass through the ignition hole and ignite the gas-generating powder in the combustion chamber. A large amount of high-pressure gas breaks throu...
