Russian Medium Twin Kamov Ka-62 to Fly in One Year

By Thierry Dubois, @aerodub

The Ka-62, a civil derivative of the military Ka-60, features new elements such as Turbomeca engines, a Transas avionics suite and a crashworthy fuel tank

Russian Helicopters is planning on flying the Kamov Ka-62 medium twin in August 2013. The new helicopter, which bears some resemblance with the Eurocopter Dauphin, will be in the 12 to 15-passenger category. The manufacturer is targeting a very aggressive price, at $8.5 million.

Four aircraft will fly in the test program, according to Anatoly Mezhevov, deputy executive sales director. Interstate Aviation Committee certification is planned for the fourth quarter of 2014, just before deliveries begin in 2015. EASA certification is in the cards, too, as the company is considering it for 2018.

The Ka-62 is a civil version of the Ka-60 Kasatka military multi-role helicopter. Kamov developed the latter in the mid-1980s. It will be marketed for a range of roles, including EMS, search and rescue, law enforcement, border patrol, training and corporate/VIP transport. Offshore oil and gas passenger transportation is seen as a major application. “Evacuation is fine for 15 passengers, thanks to four large emergency exits,” Mezhevov told Rotor & Wing.

Asked about competition against the AW139, which AgustaWestland and Russian Helicopters are to produce jointly in a new factory near Moscow, Mezhevov said the Ka-62 is introducing new technology. He mentioned a built-in self-check capability for aircraft systems.

St. Petersburg-based Transas will supply the KBO-62 avionics suite. It is built around two 12.1-inch TDS-12 primary flight/navigation displays and two 8.4-inch TDS-84 multifunction displays. Also included are the TTA-12H terrain awareness and warning system, two TNC-1G flight management systems with built-in Glonass/GPS sensors and a four-axis autopilot. The helicopter will also be equipped with a health and usage monitoring system (HUMS).

A number of new elements, compared to the Ka-60, can be found on the Ka-62. Turbomeca is powering the aircraft with two Ardiden 3G turboshafts of 1,680 shp each. They are controlled by dual-channel FADECs. A fuel tank protection system helps prevent damage in case of hard landing.

Also new are the five-blade main rotor, secondary hydraulics system, energy-absorbing landing gear and seats, and reinforced fuselage and engine mounts. Both the main rotor and the shrouded tail rotor’s gearboxes will be able to run “dry” for 30 minutes. Austria-based Zoerkler will provide the gearboxes. Mtow stands at 14,300 lbs, for a maximum payload of 5,290 lbs. Maximum range is said to be 405 nautical miles. The Ka-62’s maximum cruising speed is 157 kts.
