The main role of firefighting helicopters is to extinguish fires in the air, power transportation, investigation and command, medical rescue.
1, air fire
In the city building fire, through the firefighting helicopter loaded with fire buckets, firefighting tanks to the fire parts of the sprinkling of water or extinguishing agent, to play directly extinguish the fire or within a short period of time to reduce the temperature of the fire suppress the purpose of the fire, with the ground firefighting rescue force action; the use of helicopters equipped with The use of helicopters equipped with firefighting water cannons, directly through the windows, holes to the interior of the building spray extinguishing agent, directly to the point of origin of the fire to achieve the purpose of extinguishing the fire.
2, power delivery
The firefighting helicopter carries firefighters and rescue equipment, arriving at the target building through the helicopter top landing or rope landing device, the firefighting rescue power put to the fire scene, the firefighting rescue operations, can greatly save the time of the firefighting rescue and the rescue personnel's physical strength, applicable to the firefighters and rescue personnel, the firefighters can not take the fire elevator or climb to the firefighters. It is suitable for the fire-fighting and rescue scene which cannot take the fire elevator or climb the stairs to attack.
3, reconnaissance command
When a large-scale fire accident occurs, the fire scene reconnaissance or commanders use the helicopter map transmission to reconnaissance of the entire fire scene, or directly take the helicopter in the air on the firefighting and rescue tasks on-site command, can be a real-time comprehensive grasp of the scene information, to make the correct judgment and reasonable call ground firefighting rescue The fire-fighting and rescue forces can enhance the efficiency of the fire-fighting and rescue operations and reduce unnecessary losses and casualties.
4, medical rescue
Through the helicopter landing roof apron or through the electric winch, the evacuation of high-rise buildings on the top floor of the trapped people, and can be equipped with medical personnel and medical equipment, to the serious injuries of rapid medical treatment and timely transfer, which greatly improves the efficiency of evacuation of people in the fire scene to enhance the survival rate of the injured personnel. The company's products and services have been widely recognized by the public and the public.
Firefighting helicopter fire extinguishing principle
1, fire bucket fire extinguishing
Fire extinguishing bucket is mainly hanged in the lower part of the belly of the water storage bucket, with the control box and the water switch on the release of the fire extinguishing water or fire extinguishing agent to extinguish the fire.
But because the helicopter sprinkler water is blocked by the house roof, can not directly reach the indoor part of the fire, and in the bucket after a one-time release of the load, the aircraft flight stability will have a certain impact, so the use of fire extinguishing bucket way to extinguish the fire is generally used to fight forest fires or ground fires.
2, built-in water tank fire
Built-in water tank fire extinguishing principle is similar to the fire bucket, is through the water storage tank installed directly inside the fuselage, in the lower part of the belly of the machine to set up a water discharge port for extinguishing. As the water tank is installed inside the helicopter, it will not affect the aerodynamic performance of the helicopter, and the fire-fighting operation is more secure and stable.
But due to the water storage tank set in the fuselage need to occupy a large space, mostly used in medium and heavy helicopters, has certain limitations.
3, fire water cannon fire
Fire water cannon is through the generator, centrifugal pumps, external water tanks and other institutions, the fire extinguishing water and solvents through the spray, directly to the fire source parts of the fire extinguishing or control of the fire, the body of the gun can be generally in the front and rear of the 90 °, 45 ° downward rotation.
The pilot can be based on the location of the fire source when extinguishing the fire, maneuvering the gun body to extinguish the fire, do not need to adjust the angle of the helicopter, safety, maneuverability and flexibility have been greatly enhanced, is the most suitable for urban buildings to fight the fire fighting mode. However, due to the gun body, generator, centrifugal pump, water tanks, etc. installed in the body of the external, to a certain extent, will also have an impact on the aerodynamic helicopter.
