Bionics studies on the aerodynamics of bird flight carried out in collaboration with TU Berlin yielded insights and new ideas on minimizing turbulent drag at the wing tips. The consequent development of these ideas led to a novel shape for propellers, patented worldwide as the Bionic Loop Propeller.
The new shape reduces energy consumed and noise, especially in heavy-duty propellers
Comparison of the conventional propeller and Bionic loop propeller in wind power generation
In a comparison between a conventional propeller and a bionic loop propeller, the bionic loop propeller on average generated 30% more energy while emitting only half the noise.
