DLR and Airbus conduct new test to reduce helicopter noise

German Aerospace Centre (DLR) and Airbus Helicopters Deutschland have carried out a test that aims to reduce noise and vibration produced by helicopters.

A part of the Scalability and Risk Minimisation of Technology (SKAT) research project, the test saw the DLR and Airbus trial active rotor control on a modern, five-blade rotor in a wind tunnel.

Through the test, DLR researchers were able to reduce vibration and noise emissions during landing approaches with the five-blade rotor.

By individually controlling the blades, researchers were also able to lower the rotor noise on the ground during the approach by up to three decibels, which is equivalent to a 30% reduction.
