The plethora of rotary aircraft engines around the world
validate our concept.

Development of the Mi-38 begun in 1986 to replace the ageing fleet of Mi-8s and Mi-17s, currently in civilian and military service in Russia
and a number of other countries. The Mi-38 was expected to fly in 1993 but due to the lack of funding the project experienced considerbale delays.
The Mi-38 has a number of unique features, such as a six-bladed main rotor, extensive use of composite materials, a delta-3 type tail, CRT
cockpit displays, etc. The helicopter can carry cargo under-slung or inside the cabin, loaded via clam-shell rear doors and a loading ramp. Mil
OKB is currently cooperating with Kazan Helicopters and Eurocopter on the Mi-38 program.
"Codenamed 'Hermit' by NATO, the Mi-34 is a two/four-seat light helicopter in the same class as the Gazelle and Ecureuil, but powered by a piston engine. The first of two prototypes flew for the
first time in 1986, and the type was revealed to the West for the first time at the Paris air show in June 1987. The Mi-34 is competing against the Polish turbine-powered Swidnik SW-4 as a replacement
for the fleet of obsolete training helicopters, such as the MO, used in large numbers. However, no decision has yet been made regarding series production of the 'Hermit'. A development is also under way
to re-engine the Mi-34 with two 164-kW (220-hp) VAZ-430 rotary engines normally used to power VAZ cars, and which run on Mogas. First flight of the prototype, designated Mi-34V, is scheduled for 1993..."
