Ka 62 and modifications

Folding to the early nineties known negative situation in the country, due to the painful period of the beginning of formation of market relations in all industrial and economic structures, almost “dead” financial flows for development.

And OKB them. N. And.Kamov with the aim of attracting investment in the initiative order in 1990 expands the work on the creation of the civilian version of the helicopter In-60 under the designation Ka-62. The leadership is entrusted to the Deputy head of technical projects OKB Gubareva B. A. and leading designer Furman Century A.

Based aerodynamic shape model glider helicopter Ka-60 is based layout helicopter Ka-62, the interior of which was performed in the cargo and passenger versions. Transport helicopter cockpit up to 6.0 m2 allowed to accommodate up to 10 passengers in economy class or 6 people in the VIP-class-coupe”, or to provide mechanized loading of cargo weighing up to 450 kg

The layout of the Ka-62 in 1991 was shown at first in Russia international aviation exhibition held at ENEA.

The cockpit of the Ka-62 was equipped with a shock-absorbing seats, and the dashboard for the first time in Russian helicopters equipped with electronic equipment on the basis of liquid crystal displays , created by a team of authors, NIIAO, including employees OKB them. N. And.Kamov √ Gubarev B. A. and Krygin Century,

In the subsequent period of the nineties OKB them. N. And.Kamov reinforced promoting helicopter Ka-62, showing the layout at all, became a regular, airshows and parallel to actively negotiating joint ventures with various Western European firms, such as the British company Rolls-Royce and the Italian firm Agusta.

The Ka-62 is the first helicopter JSC “Kamov”, made of single-rotor with tail rotor in the vertical tail. Great attention in the design of the helicopter was facing increasing its efficiency by increasing the cruising speed, reduce fuel consumption and increase of weight, and by reducing the complexity of maintenance.

Held in conjunction with the TSAGI theoretical and experimental studies have allowed us to significantly reduce the aerodynamic drag of the helicopter, and the use of improved profiles and optimize the configuration of the blades is increased relative and propulsive efficiency and achieve maximum equivalent aerodynamic quality equal to 4.

The Ka-62 is built on a single-rotor scheme with multi-blade tail rotor in the annular channel of the vertical tail. Rotor blades and airframe 60 percent by weight is made of polymer composite materials. The glider is different perfect aerodynamic shape, roomy transport-passenger cabin and a tricycle undercarriage with a tail prop. The power plant includes the engines of a new generation of modular design, development Rybinsk design Bureau motors under the direction of chief designer A. S. Novikov. Civil modification from basic military uses a high cruising speed, fuel efficiency and vehicle performance, wide doorways transport cabins on both sides of the fuselage.

The helicopter can be used for transportation of passengers with adequate comfort, transportation of cargo inside the cabin and on the external load, emergency medical care, emergency and rescue, ice reconnaissance and various patrol operations, control of water borders and border economic zones, maintenance of offshore gas and oil pipelines and other

The Ka-62 is designed taking into account the international requirements for safety. Provided flight and landing with one engine. Traumatic pilot and passengers in case of a rough landing is guaranteed by a complex of measures, including energy absorbing design of the chassis and chairs. Tail rotor in Kiel protected from accidental damage. The machine is equipped with an effective anti-icing and fire systems.

Ka-62 can have as standard equipment basic transport version for flights in visual appearance, and to pilot rotary-wing apparatus instrument in all weather conditions using satellite navigation equipment. The export variant of the helicopter may, at the request of the customer to have the engines and avionics foreign firms.

In 2012, the exhibition HeliRussia 2012 presentation layout of the Ka-62, which represents the updated design of the helicopter. External scheme and layout of the helicopter were saved, major changes have affected the chassis and engine Bay because instead of Russian turboshaft engines RD-600 machine will be installed French Turbomeca Ardiden 3G. The gearbox and transmission will deliver the Austrian company Zoerkler.

Production is planned to develop on the plants of the holding company “Helicopters of Russia”: Arsenyev aviation company Progress (build helicopters) and JSC Kumape (components main and tail rotor). At this point in Arsenyev the plant started the production of two prototypes.

Test results in 2013 helicopter demanded modifications, certification planned until 2015. Until the completion of the allocated additional funding. At the same time, test flights military version is planned to begin in March 2014. In July 2014 the Transas delivered the first integrated flight and navigation system, the LED-62 for advanced machines and flight tests. Until the first quarter of 2016 should be delivered the first seven cars for export.

“Helicopters of Russia” plan to demonstrate the first flight model of the Ka-62 at the MAKS-2013 in late August of this year.
