The civil version is known as Kamov Ka-62.
Design
The Ka-60 has an estimated local military market of 200 units (Army aviation units, Border Police and the Ministry of Internal Affairs).[citation needed] The Ka-60 is to be used for aerial reconnaissance, for transporting air-assault forces, radio-electronic jamming, for special-operations missions and for various light-transport missions. Variations for foreign sale are expected. Manufacture is to take place at Ulan-Ude.
The civil version, the 6.8 t (15,000 lb) Ka-62, can carry up to 15 passengers or 2–2.5 t (4,400–5,500 lb) of cargo (internally or externally), has a top speed of 167 kn (309 km/h) and a range of 380 nmi (700 km).[4] It features a five-blade main rotor and shrouded tail rotor, and is powered by a pair of Safran Ardiden 3Gs, and later by in-development Klimov VK-1600s.[4] It has a 30-minute run-dry gearbox by Zoerkler, and can operate on one engine up to 9,500 ft (2,900 m).[5]
Development
The development of the helicopter was long. The program started in 1984, but the first prototype Ka-60-01 flew in December 1998, and the second in 2007.[6]
A civil version, the Ka-62, was initially proposed when the Ka-60 programme was launched, but no production followed owing to development problems with the Ka-60's Saturn RD-600V 1500 hp engines. Instead, an agreement was signed in April 2011 to use the 1,306 kW (1,751 hp) Turbomeca Ardiden 3G turboshaft for a revised Ka-62. The main rotor will be driven via a new transmission, while the helicopter will have a revised cabin with larger windows and new avionics. First flight of the Ka-62 was planned for May 2013, with certification in 2014. Four prototypes and an initial batch of 16 Ka-62s for the Russian Ministry of Defence were planned,[7] with another 12 ordered by South American civilian customers. Russian certification was expected in 2018, with European EASA certification following in 2020.[8]
The Ka-62 was unveiled in 2012 and flight tests began in 2017.[4] After 434 test flights with three prototypes during 700h, it was certified on 30 November 2021 by Russian regulator Rosaviatsia.[4] Deliveries should begin in 2022, planned production is six units in 2022, eight in 2023 and 10 in 2024.[4] A cargo hook, a winch, a medical module and an anti-icing system should be certified until 2024.[4]
The development and certification of the Ka-62 was suspended in late 2022 due to Western sanctions and the large number of foreign-made components (including the French-manufactured engine).[9] About 60% of the Ka-62's parts had been sourced from Western suppliers, and could no longer be imported.[10]
In 2023, a spokesman for the manufacturer confirmed that design work on the helicopter type was ongoing, including a possible effort to substitute Russian-made parts for the Western parts no longer available.[10]
