This aircraft paper model is a Eurocopter EC135 helicopter, designed by Eurocopter original site. The Eurocopter EC135 is a twin-engine civil helicopter produced by Eurocopter, widely used amongst police and ambulance services and for executive transport. It is capable of flight under instrument flight rules (IFR).
The EC135 can trace its history back to before the formation of Eurocopter. It was started as the BO 108 by MBB of Germany in the mid-eighties. A technology demonstrator ('V1') flew for the first time on 17 October 1988, powered by two Allison 250-C20R/1 engines. A second BO 108 ('V2') followed on 5 June 1991, this time with two Turboméca TM319-1B Arrius engines. Both these machines had a conventional tail rotor.
In late 1992, the design was revised with the introduction of the Fenestron tail rotor system, reflecting the creation of Eurocopter that year through the merger of Messerschmitt-Bölkow-Blohm (MBB) and Aérospatiale. The combination of lower accident potential from the enclosed rotor, and interior space, have made the EC135 popular with aeromedical helicopter operators. The EC135 is the best selling light twin of the past 10 years.
Two pre-production prototypes were built. They flew on 15 February and 16 April 1994, testing the Arrius 2B and Pratt & Whitney Canada PW206B engines, the older and less powerful Allison Model 250 powerplant having been rejected. A third helicopter followed on 28 November 1994. [Source: Wiki]
