use of helicopters

Recently, helicopters are increasingly used in various types of air works. Air works are those works in which a helicopter is not used to transport a passenger, mail or cargo, but is used as an instrument: for example, as a mobile platform on which chemical preparations are delivered for cultivating crops or destroying insects; For the operation of electronic research instruments or the search for mineral deposits; For advertising or as a lifting device for various construction works; As a fan for moving ambient air, for fear of people, etc.

Works that are intended, mainly for transport purposes, for the carriage of passengers or individuals for a fee or more for pleasure, do not apply to air works. Excluded and those transport works that are non-working, or work performed for the development of the most-aviation. These include: a private pleasure flight; Aeroclub events; Amusement trips and flights; Training and checking (crew); Aircraft research and test flights; Aircraft demonstration and record flights; gliding; Delivery flights; Flights for the conduct of, testing or verification of aeronautical ground services.

Classification of air operations in accordance with the purpose helicopters can be represented in the following way:

1. Aerial application: insect control in agriculture and forestry; supervision of animals; control over diseased plants and forest plantations; fertilization; supervision of weeds and shrubs; sowing agricultural and forestry plants; impact on clouds for precipitation; fighting forest fires; city ​​and fire fighting service; transportation of fish and wild animals.

2. Air follow-up: topographic; geological; polar; for the conservation and use of land and water resources; agricultural; silvicultural; for urban planning and construction; archaeological.

3. Aerial surveillance and patrolling: surveillance of plantations and nomadic herds; study of wild animals; patrolling forests; patrolling pipelines, power lines and communication lines; observation of flooded

and the devastated areas; control of road traffic and crowded; coast guard and border patrols; ice patrols; meteorological observations; study of cosmic radiation; Production of television films; supervision of civil works.

4. Air Construction: construction of power and communication lines and relay stations; construction of pipelines; transportation and installation of oil rigs; fencing areas of land; construction and installation of equipment at the skyscrapers; easy delivery and assembly of houses; building bridges of light.

6. Air communication: writing in the sky, signaling the creation of bands, scattering leaflets and ads through a loudspeaker; radio broadcast.

7. Indignation of air disturbances: warning freeze; drainage of moist areas of fields, playgrounds: for games; harvest of ripe fruits and nuts; prevention of damage to snow in forest plantations; scaring away birds from crops.

8. Emergency operations search and rescue operations at sea, in mountains, forests, deserts, swamps and flooded areas; ambulance and medical services; delivery of personnel and food, clothing and other types of assistance.

When air use of a helicopter is used as a mobile platform for the delivery of specific drugs, poisons to combat pests and parasites animals, for fertilization, seeding, application of chemicals for the purpose of falling off the leaves of plants, for transportation of fish fry, delivery of fire trains and water to extinguish fires, to spray "materials that cause precipitation.

These works are widely spread in many foreign countries.

Pollination of clouds to induce precipitation is used sporadically and often in order to conduct research. The use of helicopters for forest fire fighting is becoming more common in France, Canada, the United States, therefore much less they are used to fight city fires. .. The transfer of the fish, otters, pheasants, etc. with the help of helicopters is used in the United States, Canada, New Zealand; etc.

When conducting research aircraft helicopter is used as a platform from which carry out their work various optical, magnetic and electronic devices (film and photo cameras, magnetometers, roentgenometer, electro magnetometers, Geiger counters, radar recorders and so on. D.).

With the help of helicopters compiled topographic maps being sought minerals, explored vast areas in the Arctic and Antarctic are defined and projected land and water resources, provides assistance in urban planning and civil engineering, conducted archaeological research. These works are held in many countries around the world.

During aerial observation and patrolling with a helicopter, visual and instrumental monitoring of the state of the earth's surface and atmosphere is conducted, records are kept and monitoring of the movement of the herds of animals, the state of plantations, crops and forests. Helicopters for patrolling pipelines, power transmission lines (LEPs), telephone and telegraph lines were widely used. Helicopters are being inspected areas affected by the disaster (flood, collapse, fire, earthquake, etc.). They provide assistance in regulating traffic on busy highways, in coastal and border guard services, in the delivery of pilots and ships, in the ice and meteorological Rashedshka, in the study of cosmic radiation. Helicopters are used as a flying film set for: filming of TV and movie films. They are also used for inspecting construction works in hard-to-reach places.
