Aerospace reference project


Helicopter transmission systems: from development to series production

For the civil Russian transport helicopter Ka-62 we were commissioned to develop a completely new transmission system. Decisive for the project award was the high technological competence of our team and the focus on highest quality and precision. The innovative drive system of the Ka-62 consists of a main and tail gearbox and main and tail rotor shaft.

The helicopter was specially designed to transport people safely across the sea on oil platforms under extreme conditions. The helicopter of the 6,5 ton class has room for 17 passengers including the pilot and is equipped with two Turbomeca Ardiden 3G engines in addition to the Austrian transmission system. The range is 750 km at a maximum speed of 310 km/h.
