Russian Helicopters has not brought any of its rotorcraft to Le Bourget this year. But a few weeks before the Paris Air Show, the Russian manufacturer reported the first horizontal flight of its newest Kamov Ka-62 medium twin.

The first flight took place on May 25, more than a year after the first hover test. The Ka-62 prototype spent 15 minutes aloft, at speeds of up to 68 mph (110 kph).


Although Kamov, now a subsidiary of Russian Helicopters, is well known for its coaxial rotor military and civil helicopters, the Ka-62 became a true innovative model for the famous design house: it’s the first Kamov helicopter with a single main rotor. It’s also the first Russian rotorcraft that features a shrouded tail rotor.

The foreign contribution to Ka-62 includes the main transmission, designed by Austrian company Zoerkler, and 1,680-hp Safran Ardiden 3G turboshaft engines. The engines are expected to be certified very soon, while the helicopter will need about two years of trials to earn its basic certificate, say sources in the Russian aerospace industry.


The Ka-62 is to have a maximum takeoff weight of 13,330 lb. (6,500 kg) and can carry a payload of up to 4,859 lb. or 15 passengers inside the cabin. Russian Helicopters doesn’t have any firm orders for the type now, but expects the new model can be used for passengers, transport, offshore, medevac, search-and-rescue or patrol missions. According to Russian minister of industry and trade Denis Manturov, Ka-62 sales may reach 365 airframes through 2030. “Realization of this program will enable Russian Helicopters to capture not less than 20% of [global] intermediate class helicopter market by 2025,” he forecasted.
