The Konner Helicopter K1 is the first helicopter in the world to be produced with a turboshaft engine designed to run on diesel fuel.
Powered by the TK25 turboshaft engine, which is claimed to produce 250hp yet weigh only 55kg, the two K1 was one of the great novelties of AERO 2013, drawing large crowds to the Italian manuafacturer’s stand (although the wine and Parma ham being served up must have helped!) Fixed-wing devotees may be pleased to learn that a turboprop vesion of the engine is also available.
