Mil Mi-36

The Mil Mi-36 was a Soviet light multipurpose helicopter project started in the early 1980s, after the development of the 650 horsepower TV-O-100 gas turbine gave Soviet designers their first lightweight engine suited to a small high-performance helicopter. In July 1981 the aircraft industry asked Mil and Kamov to propose competing designs for a light helicopter to attack enemy armament, support troops with fire, carry personnel, wounded and loads, scout, direct fire and perform search and rescue, possibly working in pairs with the Mi-28. Mil proposed a single-rotor machine with two TV-O-100 engines, a three-bladed main rotor of 14.5 metres, an armoured two-seat cockpit with a machine gun and a cargo compartment for four soldiers or four stretchers. A second gun covered the rear, and detachable wings could carry up to eight anti-tank missiles. It was never built, and much of the thinking carried over into the Mi-40.
