Description

Automatic Fire Extinguishing System For Crew Room Of Tactical Vehicle}

The content disclosed in this specification relates to an automatic fire extinguishing system in the crew room of a tactical vehicle, and more particularly, by detecting the occurrence of a fire in the crew room of the tactical vehicle through a temperature sensor, etc. It is about an automatic fire extinguishing system.

In general, the Korean light tactical vehicle (KLTV) developed by the Korean military was mainly used for administrative support or tactical purposes such as position, communication, and weapon loading in the past, and is now also used for combat. The body has two models, a basic type and a long axle type, and is equipped with an 8-speed automatic transmission, and is equipped with the latest electronic control system such as an electronic part-time four-wheel drive system and an electronic tire pressure control system.

Recently, the KM-151 and K-351, called 'Korean Humvees', developed by Kia Motors under the government's investment for 31 months, were introduced. Although the protection and maneuverability have been further strengthened compared to the Humvee, the high mobility multi-purpose vehicle used by the United States, the price is about half that of the Humvee, and it has economical efficiency and is positioned as a small tactical vehicle for the ROK military that is expected to be exported abroad. In addition, the KM-151 and K-351 are expected to greatly help in the performance of missions such as effective combat command, search and reconnaissance, and close maintenance support by expanding their operational areas in the future. have.

Such small tactical vehicles usually have only one portable fire extinguisher installed in the trunk of the vehicle so that passengers can easily carry and transport it and spray it directly to the fire source when a fire occurs inside or outside the vehicle. A separate automatic fire extinguishing system is not installed in the crew room.

Due to these circumstances, if a fire occurs in the crew compartment of a tactical vehicle during combat or during operation, the occupant gets out of the vehicle and directly carries a portable fire extinguisher mounted on the rear of the vehicle during battle (or after stopping the vehicle while driving). Come and put out the fire. This not only results in the life of the occupant being threatened, but also results in loss of mobility and combat power.
