Whirltowers

01Single and bi-directional operation
02Minimized structural vibrations
03Unique control and testing capabilities

Our technologies for your demands

The exact design of test rigs for helicopter main gear units (MGB) requires considerable know-how about the interface to the rotor blade system and all the loads occurring there during operation. As the market leader for MGB test rigs, RENK has a very high level of expertise in this field. It is therefore not surprising that we are also the right partner for the design and assembly of whirltowers for rotor blade testing.

Our Whirltowers can be used for the following tasks in development and production:

Blade balancing
Blade development
Main rotor hub system development
Static and dynamic performance measurements

RENK test benches are exactly tailored to individual customer requirements and can, on request, include not only the drive system with rotor head mounting, but also other required elements such as measuring equipment, power supply or special building components.

01 Single and bi-directional operation

Clockwise or counterclockwise

When designing our whirltowers, we can take into account a wide range of rotor configurations. The most common are clockwise or counterclockwise turning single rotors. But also the drive and testing of coaxial counter-rotating rotors is possible.

02 minimized structural vibrations

Minimized vibrations and best efficiency

RENK is known worldwide for using state-of-the-art calculation, simulation and manufacturing methods to minimize vibrations in powertrains and increase their efficiency. And this expertise is also particularly essential in test rig construction.

03 unique control and testing capabilities

RDDS automation system

Our RDDS test stand automation system combines control and measurement tasks in one package. Test programs can be easily prepared and then executed using graphical operator guidance. A real-time interface allows communication with the blade pitch control system to simulate specified flight maneuvers interactively and realistically. All recorded measured values can be visualized and archived online.
