Its preliminary design and some specification data were unveiled at the HeliRussia 2009 exhibition near Moscow.
As Kamov Chief Designer Sergey Mikheev explained, the traditional design when the main rotor both lifts and pushes the aircraft forward functions only up to a speed of about 300 km/h due to retreating blade stall.
[3][4] However the designers plan to install more powerful 3,200 hp VK-3000 turboshafts as soon as the St. Petersburg-based Klimov Company finishes their development.
With improved aerodynamics and two rear-mounted counterrotating pusher propellers, the Ka-92 is expected to reach a cruise speed of 420 to 430 km/h.
A Russian Air Force general planned for a prototype to fly in 2018, with production in 2022.
