Fire extinguishing bomb with fine control function

Abstract

The invention discloses a fire extinguishing bomb with a fine control function, and belongs to the technical field of forest fire extinguishing. The fire extinguishing bomb comprises a barrel type empennage, a rear cover, a control module, a safety detonating device, a tail baffle, a warhead shell, a preset protection barrel, a fire extinguishing agent, a main explosive, a connecting body, a pulseengine shell, a pulse engine shell, a blocking piece, a front baffle, a closing switch and a heat detector. According to the fire extinguishing bomb, the advantages that the pulse engine is fast in reaction and can be started in situ are utilized, the low-speed flying bomb can accurately control and correct the flying posture of the bomb at the tail end of a trajectory, air shock waves generatedby explosion of the main explosive rapidly scatter forest big fire into small fire, the fire extinguishing agent forms a covering layer within the range of being exploded into the small fire in a firescene under pushing of air waves generated after explosion of the explosive, continuous combustion of the small fire can be weakened, and reburning of remaining fire can be inhibited. The fire extinguishing bomb further has the advantages of being simple in structure, safe, reliable, high in fire extinguishing efficiency, small in environmental pollution and the like.

Description

technical field [0001] The invention relates to a fire extinguishing aerial bomb, in particular to a fire extinguishing aerial bomb with a refined control function, which belongs to the technical field of forest fire extinguishing. Background technique [0002] Forest fire is a kind of forest fire that is difficult to control, spreads freely and rapidly in the forest. Once a forest fire occurs, it will bring serious harm to the forest and the ecological environment, and cause huge economic losses. [0003] Forest fires are usually divided into three types: surface fires, tree crown fires, and underground fires according to their burning objects and burning parts. Crown fire is a forest fire that burns in the tree canopy. It has combustion characteristics completely different from surface fires and underground fires. Its combustion temperature is high, the flame intensity is high, and the spread speed is fast, which is easy to cause special fire behavior. The height of most...

Existing firefighting equipment cannot directly and effectively carry out firefighting

[0004] At present, a large number of forest firefighting equipment has been developed with various types and different functions, which have played an active role in forest firefighting. However, due to the low speed of conventional aerial bombs at the end of the flight, the aerodynamic force is very small, the response is slow, and the execution is poor. , it is difficult to accurately control the flight attitude of the aerial bomb and accurately extinguish the canopy fire, so it is of great practical significance to invent a kind of fire-extinguishing aerial bomb with refined control function for fighting the canopy fire
