Fire helicopter protection

To prevent the occurrence and spread of fire to adjacent compartments, as well as detect and eliminate ignition provided appropriate positive measures, the system and detect overheating and fire equipment, fire-fighting, protection against fire in the cabins of the crew and passengers, as well as in the luggage compartment.

Fire extinguishing system consists of the following elements:

  • - cylinders with flame retardant liquid;

  • - pipelines supplying the flame-retarding liquid to the nozzles;

  • - sprays and sprinklers that turn a stream of flame-retarding liquid into small droplets or mist;

  • - heat detectors installed in the most dangerous places of the motor compartment, signaling the occurrence of a fire;

  • - screens that form a stream of cooled air;

  • - connecting and fasteners of the system.

In addition to the automatic sprinkler system provides a system including a pilot.

In case of fire in order to reduce the amount of air supplied to the gear compartment, it is necessary to provide automatic closing of the valves of the fan input from sensors, alarm installed in this compartment.

The most rational way to reduce fire hazard and prevent the spread of fire is the isolation using fire partitions the engine compartment, as well as the individual most responsible or flammable units. In addition, it is important to organize the purge motor and tank compartments provide these compartments plums, eliminate stagnant zones, which would collect fuel or its vapors, and fill fuel tanks with inert gas.

If the accident helicopter fire safety soft tank is higher than the hard.

Structural measures that reduce the risk of fire in case of emergency landings are:

  • - automatic de-energization of the electrical system of the apparatus, overlapping of remote electric fuel fire cocks;
  • - the use of dumped additional tanks;
  • - metallization of SU units;
  • - the use of protected soft tanks.

On the occasion of cylinders with a flame-retardant liquid, it should be noted that in case of unauthorized activation of the fire-extinguishing system, variations in the operation of the SS and other units are possible. For example, the balloon is located next to the fire extinguishing component, in this case it is worth considering the options with the possibility of short-circuiting the violation of the combustion reaction, etc. and in aircraft construction at high speeds and different positions of the aircraft, the fire extinguishing system pocket must follow these conditions. The earth's gravity and the direction of the flow of air. (Well, let me puumnichat :))
