If there is no moulding case available, it is possible that our toolmaking section builds potting-forms. With small series this is cheaper than a die-casting
case.

Potting of piezo ceramic actuators for rotor blades of an helicopter with electric flap drive.
|
|
The control is done by three flap modules attachted to the backside edges of each rotor blade. The blades have integrated piezo ceramic actuators, which
react with a change of length to variable electric voltages. Like this the rotor flaps are moved about 15 - 40 times per second.
For the future the primary goal of this innovative control method is to reduce teh relatively high noises of the rotor blade peak vortex, which are system
related for helicopters during the flight. Even though the limits are already underbidden by today, the reduction should reach a level which is clearly below the limiting values of modern
Eurocopter-helicopters.
Contemporary the vibrations that have an effect on components and passengers should be decreased remarkable. This will increase teh flight comfort and the
limit of performance of future helicopters. Furthermore teh commercial usage of helicopters will benefit
