Kamov Ka-62 Passenger and Cargo Transport Aircraft, Russian Federation
The Ka-62 is a twin-engine medium utility helicopter being designed and manufactured by Kamov Design Bureau of Russia. It can carry out passenger and cargo transportation, medical evacuation, search and rescue, ice reconnaissance, oil and gas pipeline maintenance and highway patrolling missions.
The helicopter is derived from its predecessor Ka-60 military aircraft. Its initial operational capability is scheduled for 2014.
Variations of the Kamov Ka-62 aircraft
An advanced version of the aircraft, the Ka-62M, is planned to be built at Komsomolsk by KnAAPO for export to foreign countries. It will feature two 1,212kW GE T700 or CT7-2D1 turboshaft engines driven by a five-bladed main rotor and avionics to be supplied by Aviapribor.
Orders and deliveries of the twin-engine medium utility helicopter
The Turkish Ministry of Public Health announced its plan in April 2001 to procure six Ka-62s at a cost of $31.5m, for executing air ambulance missions.
About 200 Ka-62s were ordered by India in June 2007.
Design of the passenger and cargo transport aircraft
The Ka-62 has been designed to operate from unpaved airstrips and short runways even in hostile climatic conditions. It has been designed to meet international flight safety requirements.
The aerodynamic design of the fuselage enables the helicopter to be highly resistant to angles of attack. Approximately 60% of the airframe is made up of polymeric composite materials.
The Ka-62 features an anti-torque rotor to prevent accidental damage. It houses an advanced thermal electric anti-icing system, air conditioning system, fire prevention system, tailboom, fin, vertical stabilisers, gearboxes and rotor blades of carbon strengthened Kevlar.
The helicopter is equipped with a modern avionics suite suitable for visual flight rules (VFR) or instrument flight rules (IFR) flying conditions.
A large forward sliding door is fitted on either side of the flight deck. There are small rearward attached doors on both sides of the cabin.
Flight deck of the Kamov Ka-62
The all-digital glass cockpit of the Ka-62 accommodates two crew members.
The spacious cabin of the Ka-62 is 3.4m long, 1.7m wide and 1.3m high. It can carry 14 passengers in four rows or 2,500kg of freight. The aircraft includes a 2.16m3 baggage compartment for passengers.
The cabin can carry cargo pallets or bulk cargo on external sling when deployed as freight carrier. The helicopter can be easily reconfigured to carry a stretcher and cargo tiedowns.
It will also be available in VIP configuration with five to nine seats and a refreshment bar.
The Ka-62 is powered by two Turbomeca Ardiden 3G turboshaft engines rated at 1,306kW of output power each. It was initially powered by NPO Saturn RD-600V turboshaft engine rated at 969kW of power, but the engine was replaced due to high fuel consumption and troubles in the gear box.
In April 2011, Turbomeca was contracted to supply a 308 Ardiden 3G turboshaft engine for installation in the Ka-62.
Turbomeca obtained its first fixed firm order from Russian Helicopters in May 2011 to build and deliver 40 Ardiden 3G engines under the existing 308 engine supply contract. Deliveries of the first 40 engines will be concluded in 2013.
The Ardiden 3G is equipped with dual channel full authority digital engine control, accessory gear box, dual stage centrifugal compressor, reverse flow combustor, fuel injectors, an oil tank, single stage high pressure turbine and dual stage power turbine.
Landing gear of the Kamov Design Bureau's Russian helicopter
The Ka-62 has a tricycle type retractable landing gear fitted with a single KT-217 main wheel and twin rear wheels. The main wheel retracts inwards into the fuselage while the rear wheels retract into tailboom. It also houses shock absorber units and optional blow-up pontoons for deployment in water during emergencies.
The Ka-62 can climb at the rate of 11.7m/s. Its maximum speed is 300km/h while the cruise speed is 270km/h. Its range is 770km and service ceiling 5,000m. The maximum endurance of the aircraft is 4.3 hours.
