Eurocopter EC135

Low operating costs, spirited performance, and what is claimed to be the lowest noise produced by any helicopter in existence make the Eurocopter EC 135 the best seller in its class. The light twin IFR rated helicopter is used in police operations, for emergency medical services, training, and utility. It can seat seven in addition to its pilot.

The Eurocopter EC 135 has an all composite four blade main rotor attached to a single piece rotor head. This is bearingless with moving components having a mean time between failure rate of a minimum of 3,000 hours. A digital electronic engine power system provides maximum power combined with efficiency.

The aerodynamic fuselage is made of a composite Kevlar material for strength, light weight, and longevity. It and all seats are made to withstand deceleration rates of 30 g. The Fenstron tail of the helicopter keeps noise low by placing its rotor blades asymmetrically. Clamshell doors in the rear storage area make access easy. The fuselage shape minimizes drag and allows more engine power to be converted to speed.

The Eurocopter EC 135 was certified in June of 1996 and ten units had been delivered by year’s end. Original production was slated at about five helicopters every three months. However, at its peak, demand had pushed production up to five helicopters every two months. More than 1,300 have been built to date.
