Turbomeca inks contract for Ardiden engines on Kamov Ka-62 medium twin

Russian Helicopters and engine manufacturer Turbomeca announced last month that they signed contracts for the supply of “at least 308” Ardiden 3G turboshafts to be installed on the “updated” Kamov Ka-62 medium twin. The Ardiden 3G is an Ardiden 3 variant producing 1,700 to 2,000 shp.

This announcement follows the “protocol of intentions” signed in February last year. Since then, the airframer had also been considering Pratt & Whitney Canada, Motor Sich and NPO Saturn.

The contract announcement seems to kick-start the protracted program. Certification is now pegged for 2014. The 14,300-pound-mtow Ka-62 will feature a shrouded tail rotor and an anti-icing system. Half the airframe is made of composite materials.

In addition, the Fadec-controlled engines will provide what Turbomeca describes as “exceptionally low” fuel consumption. The Ka-62 can accommodate 12 to 14 passengers in the cabin or 5,500 pounds as a sling load. Cruise speed is 146 knots and range 415 nm. Russian Helicopters is saying that the new rotorcraft is designed for offshore oil operations, search-and-rescue missions and corporate transportation.

Turbomeca and Russian Helicopters also have begun developing after-sales service for Turbomeca-powered Russian rotorcraft.

The Ka-62 is something of an unexpected competitor for the 15,000-pound-class AgustaWestland AW139. In the 1990s, the Ka-62 was initially to be a joint program between the Russians and Agusta, a predecessor company of AgustaWestland. But the latter firm eventually collaborated with Bell on the AB139 joint program, .now known as the AW139.

Notwithstanding this background, Russian Helicopters and AgustaWestland confirmed in May that their joint AW139 factory in Tomilino, near Moscow, will start production this year.
