Ka-18. A photo. History. Characteristics
Ka-18 - this four-modification of the Ka-15. Designed machine in 1956, the aircraft MB Malinowski. For the first time the Ka-18 13.10.1956 lifted into the air. Compared to the base model in the rotary wing extended tail boom and fuselage, increased the number of pucks and tail extended cab. In addition to the pilot, in the cockpit of the helicopter is equipped with a room for three passengers. It is also possible to transport a sick person on a stretcher with an accompanying medical staff.
In 1957 year began public testing Ka-18, which was successfully completed in the next year. Serial production of the model established at the aircraft factory in Ula-Ude. In 1958, he participated at the World air show in Brussels, where he received a gold medal. Total produced about the existence of the production of copies of Ka 200-18.
• Passenger-cargo variant - for the transport of people, freight, mail and luggage inside the fuselage. It equipped with heating system.
• patrol option - to patrol the area by the police and the rule of law.
• Cleaning option performs the transportation of injured and sick people. The structure includes a heating system design and installation of the oxygen.
In 1958-1963 years created a special fiberglass helical blades B-7 for Ka and Ka-18-15. According to the developers, to make them have to apply the new cooking system in autoclaves under the influence of the press. This type of production gave absolutely identical in weight and size of the items that was a big step forward in the helicopter. New blades are durable, resistant to weather fluctuations, quickly produced and could radically alter the structure of the helicopter.
The secret of the production of the blades he shared Nikolay Ilyich Kamov"The autoclave polymerization does not occur all the blades B-7 as a whole, but only a single loop of the spar." Construction of a closed-section blades made of fiberglass and impregnated with binders hot polymerization: the elements of the anti-icing system and centering loads. glass sheets are formed into packets and give in precompressed. Further, they are connected with each other and establish tube centering and anti-icing system loads.
Then, in the cavity of the spar and set the rubber bladder is placed entirely in the form of pressing, equipped with electric heaters. Nitrogen, which is used in the process, creates a pressure chamber in the rubber. Visually mold repeats bends the desired product. After the pressing of the spar must be further processed. The tail section of the blade is attached to the spar. These sections are made of glass cloth sheathing with foam filler.
The formation of sections also comes under pressure in a hot state. Between them installed rubber pads. Mounted on the blade to the hub by a steel node consisting of bolts on the butt. Such a mechanism for the creation of the blades requires two times less labor input, while the quality of the final product is increased.
The plant them. Kamov conducted tests 6 sets of blades made of fiberglass B-7 and 11 wooden blades LD 10M. Plastic material has proved itself much better: their polar screw almost perfect match, while the wooden blades had a strong disagreement. Also screws, constructed from the blades B-7, distinguished increased thrust at maximum speed. The difference was about 45 kg payload. Destruction in the compartments of the blades during testing have been identified.
For a long time the Ka and Ka-18-15 exploited by many countries in the world that allowed us to obtain a huge experience of practical helicopters coaxial design.
The equipment consists of the engine control devices and carrier systems, navigation equipment, sanitary, heating and other equipment, anti-icing system, radio and electrical equipment.
The dashboard displays the pilot places a lot of indicators. Here are the altimeter VD-10, speed indicator US-250, 10 vario-BP, a magnetic compass, artificial horizon AGK-47B and watches. A good level of equipment of the helicopter navigation devices allows you to fly at any time of the day; night in severe weather conditions, the flights to Ka-18 impossible.
Sanitary version of a helicopter equipped with a special (removable) equipment, which includes: oxygen plant, stretchers, tie belts, feeding cup and thermos. Non-removable sanitary facilities: Buffet medic and helicopter kit. To rebuild the passenger version of the Ka-18 in sanitary, remove the front passenger seat and in its place establish a removable medical equipment.
To make a flight in the cold season provides the presence in the heating system of the helicopter, the main elements of which are electric heater and heated-air supply lines to the bottom of the pilot's seat and passenger. Designers managed to expand the geography of operation of Ka-18 by introducing into the design of anti-alcohol system. Its purpose is to provide the flight at the time of freezing of some components. The essence of this system is based on the principle of washing screw blades, glass cockpit-icing fluid that breaks the ice and prevents its further appearance.
Wiring Ka-18 single wire, are included in the electrical generator and the battery voltage generating 24 V. DC system even works on one battery connected to the on-board electricity network.
The main source of electricity - generator GSR 3000m that spins the engine, near which it is located. Emergency power supply - batteries, the total capacity of which is 10 Ampere-hours.
Food and radio navigation devices that require AC converters passes through 100M and MA-PAG-1F.
To carry out radio communication with ground command posts and other helicopters and planes in the Ka-18 equipment includes VHF simplex transceiver station RSIU-3M. The frequency range in which it operates the station is 100-150 MHz. There quartz stabilized frequency transmitter and receiver, which provides secure communication during the flight.
Ka-18 (NATO code Hog - "Hog") - a multi-purpose helicopter. Sproektirvoan Kamov design bureau under the leadership of chief designer Nikolai Kamov Ilyich, direct layout Malinowski MB Is a variation of the Ka-15, which has lengthened and widened fuselage. Capacity pilot 1 and 2-3 passenger. The prototype was built in 1956.
Awarded a gold medal in Brussels 1958 at the World Exhibition.
Built around 200 machines. Ka18 located in use around 20 years. Since the beginning of 1970-x Ka18 I began actively replaced with a newer model of the Ka-26, however, some machines were in operation in the early 1980-ies.
- Passazhirskiy- luggage transportation, people, mail, various goods in the fuselage (a heating system).
- Sanitarnyy- transporting the injured and sick. (Ustanovkk is oxygen and the heating system).
Ka-18 plays a role in the film "Russian Souvenir» (1960). Pilot test Efremov Dmitry K., according to the director Grigory Alexandrov, planted on the deck river ship the helicopter, and then gallantly helped the actress Lyubov Orlova get out of the cab.
