Kamov Ka-118

Type: Light multi-purpose turbine powered helicopter.

Program: Decision to build Ka-118, utilizing jet thruster control system developed on Ka-26SS test bed, announced at Helicopter Association International convention Dallas, Texas on February 4, 1990.

Design features:
Single main rotor, with swept blade tips, breaks with Kamov traditional use of coaxial contra-rotating rotors; jet thruster control system (similar to McDonnell Douglas NOTAR) eliminates need for tail rotor; highly streamlined, extensively glazed cabin; V tail with bridging tailplane; skid landing gear.

Four-blade rotor of composites construction.

Power plant:
Not decided early 1992; alternatives include one 530 kW (710 shp) Omsk TV-O-100 turboshaft, or one or two engines of Allison, Pratt & Whitney Canada, Rolls-Royce, or Turbomeca design; standard fuel capacity 700 liters (185 US gallons; 154 Imp gallons).

Accommodation: Pilot and four passengers in cabin.

Equipment: As necessary for day/night normal/adverse weather operation, on such duties as passenger transport, air ambulance, freight carrying, search and rescue, patrol of forests, highways, electric power lines, gas and oil pipelines.

So, the Russians did build a Little Bird-type helicopter. Or at least they proposed one.

But it looks like the lack of appropriate domestic engines was still an issue (if I'm reading it correctly those are a pair of Pratt & Whitney Canada engines)?
