Kamov Ka-15 Hen / Ka-18 Hog

Taking into account the experience gained in establishing helicopters Ka-8 and Ka-10, NI Kamov designed a much more practical double multipurpose helicopter Kamov Ka-15. It had a closed cab and four-wheeled landing gear. The helicopter to be used as an observer for ice-breakers, merchant vessels, and ships the Navy of the USSR.

The helicopter Ka-15 twin-preserved coaxial scheme, based on the well-established Ka-10. It was first installed engine Ivchenko AI-14V output of 168 kW (225 hp) and later - the engine Ivchenko AI-14VF turbo power of 209 kW (280 hp). In addition to producing for the Navy Soviet Ka-15 helicopter, the reports of NATO called "Hen", published serially and for civilian use under the symbol Ka-15M.

The Kamov Ka -15 stems from the Ka-10, which flew for the first time in September 1949, which was built in 12 copies. It flew for the first time in 1952, but is known in the Western world that from its operations in Aeroflot in 1955. It was built especially for the Soviet Navy, which uses it from the decks of ships for connections, comments and all other military uses, such as training personnel for example. The civilian version has been widely used for forestry and agricultural recognition of schools of fish, postal routes, monitoring missions and pipelines for small transport. Fitted with two stretchers outside, he also served as medical evacuations. The production of this helicopter purpose seems to have stopped the benefit of the Ka-26 helicopter, more modern, but its use is still widespread in the Soviet Union.

Modifying the Ka-15 with an elongated fuselage to accommodate four passengers, was the Ka-18?. The reports of NATO called "Hog". At the K-18 as the power plant used engine Ivchenko AI-14VF turbo. The Kamov Ka-18 derives directly from the Ka-15; it borrows primarily rotors and transmission. It had two coaxial contrarotating rotors. Les rotors tripales sont enti�rement articul�s. Leur vitesse de rotation est de 333 tr/mn. The three-rotors are fully articulated. Their speed is 333 rpm. The blades are made of wooden frames covered with a coating of plywood with insertion of plastic foam in the spaces left free.

The fuselage is a front structure in tubular steel welded with light alloy cladding and a rear-shaped beam, monocoque construction, light alloy. The cabin is closed and for a pilot and three passengers sitting in seats side by side and two to two. Access to the cabin is by the side doors slide backwards.

The first copy was built in 1956 and began testing in 1957. The helicopter, now gradually replaced by the Ka - 26, a 26, especially with civilian use in the Soviet Aeroflot for different missions: one as the first carriage of mail or two to three passengers, as a second ambulance with a small special loading door at the front of the fuselage to receive a stretcher and a person accompanying a third option for spreading agricultural work. The Ka-18 is also used for forestry, mineral exploration, escorting vessels in polar areas, etc ... In view of its storage vessels, the rotor blades can be made easily and lift by two people in less than five minutes.
