Kamov design bureau resumed its program to develop medium-lift helicopter

In order to increase its market share in the civil helicopter, the Kamov design bureau resumed its program to develop medium-lift helicopter Ka-62, but even in modified form. The modified prototype of the new Ka-62 was introduced at the site of the holding company "Helicopters of Russia" at the Farnborough Air Show.

According to the chief designer of the Ka-62 Alexander Vagina, this program is a priority for the CB due to the presence of large and urgent order from the Ministry of Defense of Russia. The development program of the military option Ka-60 and its civilian version of the Ka-62 was launched in 1984, the layout of the latter was presented in Moscow in September 1990 was subsequently built two prototypes: the Ka-60-1 first flew in December 1998 g, and the Ka-60-2 in September 2007 Neither one nor the other so far do not appear in the air.

What is new is available in the Ka-62?

Due to lack of funding the development of a turboshaft engine for the Ka-60, the proposed CB "Saturn" RD-600V capacity of 1,300 liters. s. was never completed, and the project is out of date.

Instead, the upgraded Ka-62 is equipped with two turboshaft engines, French Turbomeca Ardiden 3G capacity of 1776 liters. with., and emergency power 1941 liters. s. The excess engine power to emergency mode allows you to continue flying even if one of the engines stop. Another engine which is seen as a possible power plant, is the development of the Ukrainian company "Motor Sich" MS-14 and the Canadian RT6 (Pratt &Whitney).

In April 2011, the company Turbomeca signed an agreement for the purchase of 308 engines (for the four prototypes and 150 series helicopter), the contract for the purchase of the first 40 engines Ardiden was signed May 19, 2011 According to the Vagina, the French company will deliver the first two engine December 2012

But the engine for the Ka-60 RD-600V was not the only unfinished system: transmission projects and the main gearbox also never saw the light. The destruction of the first prototype of the Ka-60-2 in June 2010 was caused by fatigue phenomena in the rear gearbox.

Accordingly, the Kamov design bureau is looking for a new producer who would be able to design and produce a new transmission for the upgraded Ka-62. Russian companies that were responsible for the initial draft of the transmission and its development is reported to have refused the offer of the Kamov design bureau. The reasons include high utilization in the performance of this order and the lack of opportunities for the production of durable transmission (of new technologies and tools).

As a result, the Austrian company has been selected Zoerkler Gears GmbH, having experience in the design and manufacture of high precision drives and gear teeth. According to Alexander Vagina, although the Austrian company has no experience in the manufacture of helicopter transmissions (except for the small helicopter UAVs), it has the necessary equipment and experience in related fields. Zoerkler Gears, in turn, with the interest for itself a new market and expects to deliver the first set of transmission to be installed on the Ka-62 in early 2013

Other changes in the project was the new passenger cabin windows, which are now all can be used as emergency exits, and this will help to meet the requirements for the safety of the helicopter. The front and rear windows of the original version of the Ka-60 were lower.

In order to improve security and speed KB narrowed fuselage and three piece mounted in a row. This configuration meets the safety requirements of the helicopter emergency exit unaided.

Basic dimensions of the passenger compartment remained the same, but the bridge separating the cockpit from the passenger compartment, was eliminated. According to the developer, the passenger cabin gives each of the 12 passengers 8.6 m3 of volume, which is the highest for the helicopter in its class. Volume luggage compartment is also located at the rear of the fuselage, where previously housed the auxiliary power unit (APU). Ardiden engine APU is required.

New impact-absorbing seats AK-2000 for the members of the crew and passengers are being tested, as well as shock-resistant fuel system manufactured by Zodiac Aerospace. In order to remain competitive with Western models of equipment on the Ka-62 is five-blade main rotor, designed to reduce noise and vibration.

The main chassis fairings is another difference between the upgraded Ka-62. In flight, the main landing gear retracted slightly in fairings and the tail wheel retracts into the fairing under the beam tail rotor.

The modernized Ka-62, the most modern avionics CWE-62 with LCD monitors production Petersburg company "Transas". Avionics has much in common with systems developed "Transas" for helicopters Mi-8, Mi-17 and Mi-38.

Besides the two pilots, the usual load for the Ka-62 is the 12 passengers that can be carried at a distance of 600 km.

Anticipated problems and production

Variants include the Ka-62 modification for VIP-transport, medical, search and rescue and patrol. Launch customer for the helicopter is the Russian Ministry of Defense, and the first copies will be used to transport troops and landings. Will then be developed special modifications, including an option for reconnaissance and targeting, as well as the marine version of the Ka-65.

The Russian Defense Ministry is counting adopt the Ka-62. Apart from the problems of pilot training, the easiest helicopter standing on the Russian Air Force, is a 11-ton Mi-8. This helicopter can take loads of up to four tons, but usually it is used to transport lighter loads weighing several hundred pounds, or only a few passengers. Half the size of the Mi-8 and Ka-62 will fulfill this role in the Russian armed forces at minimal cost.

In accordance with the state armament program for the period 2011-2020 years. The Ministry of Defence of Russia should get the first Ka-62 in 2015, and that is what caused the recent acceleration of the program.

In addition to the four prototypes for the Russian armed forces will be delivered the first batch of 16 Ka-62.

For more than 20-year history of the program Ka-60/62 production site for them has been changed several times, in the 1990s. it was considered to Ulan-Ude Aviation Plant (manufacturer of the Mi-8), followed by plant RAC "MiG" in Lukhovitsy (not previously produced helicopters), and from 2006 as featured in this plant "Progress" in Arsenyev (output leads helicopters The Ka-52).

On the basis of the contract of 2011 on the "progress" of the Kamov design bureau is the production of the first four Ka-62.

One is for the resource isytany, and three — for flight.

According to Alexander's Vagina, and if all goes well, all four helicopters will be ready in 2013 and the first flight is scheduled for May 2013 on the eve of a public debut in August at the Moscow Air Show in 2013.

The teaching of the type certificate from the Russian aviation authorities planned for the end of 2014, followed in 2017 followed by a European certificate EASA.
