Template:More footnotes Template:Infobox aircraft The Kamov Ka-92 represents a proposed high-speed compound helicopter featuring coaxial rotors, developed by Kamov in Russia. It was designed as a contender against the Mil Moscow Helicopter Plant for a Russian government initiative valued at $1.3 billion aimed at creating an advanced high-speed rotorcraft.[1][2]
Design and development
The Ka-92 is an element of a program initiated by the recently formed Russian Helicopters corporation, targeting the development of a new class of medium-sized helicopters capable of cruising near 500 km/h (312 mph) with an operational range extending up to 1400 km. Initial design concepts and some technical details were disclosed during the HeliRussia 2009 exhibition held close to Moscow.
Characteristic of Kamov’s designs, the Ka-92 is equipped with a distinctive coaxial rotors configuration. Similar to the Mil Mi-X1, it incorporates a pusher propeller; however, Kamov's approach employs two such propellers instead of one as chosen by Mil. Sergey Mikheev, Kamov’s Chief Designer, explained that conventional rotorcraft designs where the main rotor provides both lift and forward thrust are limited to speeds around 300 km/h due to retreating blade stall. He stated, "Our strategy is to separate the roles of vertical lift and horizontal propulsion between different rotor systems."
Designed to accommodate approximately 30 passengers, the Ka-92 has an anticipated maximum takeoff weight near 16 tons. The initial prototype will be powered by two Klimov VK-2500 turboshaft engines paired with an innovative gearbox system.[3][4] In the future, more powerful VK-3000 turboshaft engines delivering around 3,200 hp each are planned for integration once development by the St. Petersburg-based Klimov Company concludes. With aerodynamic enhancements and two rear-mounted counterrotating pusher propellers, the Ka-92 aims to achieve cruise speeds between 420 and 430 km/h.
Due to decreased government funding and high operational expenses, responsibility for advancing the Mi-X1 and Ka-92 projects shifted from the Ministry for Industry and Trade to the Ministry of Defence in 2015. A general from the Russian Air Force indicated intentions for a prototype flight in 2018 and anticipated commencement of production by 2022.[5][6][7]
